Abstract:

A method of the production of polyvinyl butyral films with silver nanoparticles was developed. Properties of the resulting films as anti-reflecting coatings for silicon photovoltaic converters (photoconverters) were studied. The experiments were carried out on samples with and without Si3N4 coating. It was indicated that, at maximum concentration of silver nanoparticles (7 mmol/l), the increase in the external quantum efficiency in the spectral range from 500 to 1000 nm was more than 20 % for the samples without Si3N4 coating. In the case of the engineered functional coatings onto the photoconverters with Si3N4, the quantum efficiency increased on average by 10 % in the range from 400 to 1000 nm, and by 15–20 % in the range from 320 to 400 nm.

Abstract:

Purpose. Solar energy represents a sensible use alternative of thermal, chemical and nuclear current sources. Solar radiation can satisfy the growing needs of humanity with its energetic resources. Nowadays the actual problem is the development and production, of high-effective and economical photo converters (PC). Thus we need new technologies and materials. Semiconductor PC allows producing solar energy converting in electric with the help of homo-or heterojunctions. About 91 % of falling luminous flux energy is converted into electrical current through the charge carriers release out of semiconductor’s volume. The base of their quality raise is getting high-effective silicon nanostructures, their using will raise considerably PC efficiency. Due to their high efficiency, temperature stability, and low sensitivity to radiation exposure, heterostructure-based photoconverters are the most promising for the use. Methodology. In the article the technology of PC production on the base of silicon structures with heterojunctions ITO/n-Si/n+-Si is proposed. Getting of these layers with the pulverization method on the surface of silicon plates is based on the results of the heating temperature optimal values determination, deposition speed and ITO layer thickness, outflow speed of the gas stream from the spray nozzle, concentration of InCl3 to SnCl4 in spirit and other factors. Results. The represented conception of technology development ITO/n- Si/n+- Si junctions helped to define reasons that determine the character of ITO layer conductivity, depending on SnO2 content in it and their influence on the quality of photoelectrical converters on their base. Originality. The technological peculiarities of getting these layers with pulverization method, operational reliability and efficiency are revealed. Practical value. These tasks solution will lead to the modern technological processes modelling, to the raising of PC quality and, in the case of its consumer properties maintaining, to the use of modern supplies of silicon production and semiconductive materials.

Abstract:

Abstract This paper discusses multijunction solar cells with optically coupled p-n junctions under radiation exposure photosensitivity spectral response study. It is shown that if the measurement technique does not consider the luminescent coupling and does not track the optical coupling degradation, then instead of a decrease (which is a natural response of a photoconverter to radiation damage), an abnormal increase in the narrow-bandgap photoresponse (receiving luminescent radiation) subcell due to radiation damage can be observed. Accordingly, with an increase in the irradiation dose, an increase in the subcell photocurrent forming a “negative” degradation dependence of MJ SC being used in space applications is recorded.

Abstract:

The fluorescent protein fromDendronephthyasp. (DendFP) is a member of the Kaede-like group of photoconvertible fluorescent proteins with a His62-Tyr63-Gly64 chromophore-forming sequence. Upon irradiation with UV and blue light, the fluorescence of DendFP irreversibly changes from green (506 nm) to red (578 nm). The photoconversion is accompanied by cleavage of the peptide backbone at the Cα—N bond of His62 and the formation of a terminal carboxamide group at the preceding Leu61. The resulting double Cα=Cβbond in His62 extends the conjugation of the chromophore π system to include imidazole, providing the red fluorescence. Here, the three-dimensional structures of native green and photoconverted red forms of DendFP determined at 1.81 and 2.14 Å resolution, respectively, are reported. This is the first structure of photoconverted red DendFP to be reported to date. The structure-based mutagenesis of DendFP revealed an important role of positions 142 and 193: replacement of the original Ser142 and His193 caused a moderate red shift in the fluorescence and a considerable increase in the photoconversion rate. It was demonstrated that hydrogen bonding of the chromophore to the Gln116 and Ser105 cluster is crucial for variation of the photoconversion rate. The single replacement Gln116Asn disrupts the hydrogen bonding of Gln116 to the chromophore, resulting in a 30-fold decrease in the photoconversion rate, which was partially restored by a further Ser105Asn replacement.

Abstract:

ABSTRACT:Particular attention has been recently devoted to the development of biohybrid photoconverters based on the bacterial Reaction Center (RC) of Rhodobacter sphaeroides. This highly efficient photoenzyme has a conversion yield close to unit that makes it extremely appealing in the field of artificial photosynthesis. Isolated RCs suffer of a limited absorption cross-section in the visible spectral region that limits their applicative employment. Here we report the synthesis of two heptamethine cyanine molecules, whose photophysical properties make them potentially suitable as light harvesting antennas for the RC.

Abstract:

Fluoro-Ruby, the fluorescent tetramethylrhodamine-dextran-amine used to demonstrate anterograde axon transport, has been successfully photoconverted and subsequently localized by electron microscopy. The photoconversion was accomplished by irradiating the tissue with green light while bathing it in a solution containing DAB. The tissue could then be examined by brightfield microscopy or processed for conventional electron microscopy. Potential advantages of the technique include greater permanence and contrast at the light microscopic level and the ability to resolve synaptic connectivity at the electron microscopic level.

Abstract:

Photoconverters (PCs) of laser radiation (LR) for the range 520 - 540 nm based on GaInP/GaAs heterostructures have been investigated. It is shown that a decrease in the CuPt ordering in GaInP layers due to the introduction of antimony atoms leads to a short-wavelength shift of the absorption edge with a simultaneous increase in the open-circuit voltage. An increase in the total thickness of the photoactive layers of PC results in an increase in the spectral response. The performed optimization allows increasing the efficiency of the LR PC from 39.4% to 44.4%.

Abstract:

The paper proposes the development of new approaches to the creation of emergency response systems using non-traditional power supplies in the event of damage to traditional power supply systems.The main idea of the work is the formation of integrated approaches to alternative methods based on the phenomenon of acoustic emission (AE) using an unconventional power source based on film solar cells on flexible substrates. The creation of photoconverters based on thin films from a variety of materials and compounds is a promising direction in the development of solar energy. Unfortunately, the efficiency of these photoconverters is not yet high enough, but the cost of equipment for their creation, and hence the cost of instrument structures, is already quite acceptable.The investigated solar cells were obtained by the method of thermal vacuum evaporation using a UVN67 vacuum unit with modified internal equipment.After manufacturing, solar cells (SCs) were investigated under standard laboratory conditions adopted for the study of solar cells for ground-based use, i.e. in the AM 1.5 mode with a luminous flux power of 100 mW / cm2 and a temperature of 25 ° C. To study degradation processes in such solar cells after measuring the initial parameters The solar cells were placed in a sealed plastic box and kept for 4 years at a temperature of 15-25 ° СChecking the elements demonstrate high degradation resistance, which provides general requirements for the material and the conditions for its creation promising for use as unconventional sources of power supply for emergency response systems and ensuring the use of information and technical methods for preventing emergency situations as a result of fire in conditions of damage to the power supply of emergency response systems.

Abstract:

The possibility of lateral Ga (In) AsP nanostructures grown by a catalytic method in a quasi-closed volume from phosphorus and indium vapors on the GaAs (100) surface as an antireflection coating for photovoltaic devices is considered for the first time. It is shown that at fixed growth temperature, it is possible to control the surface morphology by changing the growth time. The surface morphology was investigated by scanning electron and atomic force microscopy. The dependence of surface reflection coefficient in the range of 400-800 nm on the surface structure is shown. The use of such coating in GaAs-based photocells demonstrated a significant increase in the external quantum yield of photoconverters.

Abstract:

Phthalocyanines are synthetic dyes which are shown to be good photoconverters which can be applied in a photoelectrochemical cell constructed of semiconducting and metallic electrodes. By means of spectroscopic investigation (absorption,fluorescence and photoacoustics) we have followed spectral properties of phthalocyanines complexed with metals dissolved in polyvinyl alcohol solution in order to determine the pathways of deactivation of their excited states. Spectroscopic investigations were accompanied with photovoltaic/photocurrent and current-voltage characteristics of the photoelectrochemical cell with dyes. It has been shown that there is a correlation between dye fluorescence feature and dye ability to electric photoconversion. The comparison of new data for metallic phthalocyanines with those obtained for porphyrins is discussed.

Abstract:

The recent development of serial crystallography has popularized time-resolved crystallography as a technique to determine the structure of protein-reaction intermediate states. However, most approaches rely on the availability of thousands to millions of microcrystals. A method is reported here, using monochromatic synchrotron radiation, for the room-temperature collection, processing and merging of X-ray oscillation diffraction data from <100 samples in order to observe the build up of a photoreaction intermediate species. Using this method, we monitored with a time resolution of 63 ms how the population of a blue-light photoreceptor domain in a crystal progressively photoconverts from the dark to the light state. The series of resulting snapshots allows us to visualize in detail the gradual rearrangement of both the protein and chromophore during this process.

Abstract:

Traumatic wounds represent a fairly common reason for the admission of dogs to a veterinary practice. In elderly patients, the management of wound healing can be challenging due to both the concurrent diseases and impaired physiological states, potentially resulting in delayed healing and chronic or non-healing wounds. The aim of this article is to describe an innovative therapy based on photobiomodulation (PBM) for the management of acute traumatic wounds with significant tissue loss in aged dogs. Two mixed breed dogs were presented with similar wounds in the cervical region and were managed with a fluorescence biomodulation system, a form of PBM, which consists of a photoconverter topical gel that is illuminated with a blue light-emitting diode lamp, applied on a weekly basis. Wound closure was achieved after 9 and 16 weekly treatments, respectively, with a complete re-epithelisation of the skin. This fluorescence-generating system is an innovative, non-invasive, wound care therapy and these results indicate it could be successfully applied in the management of acute traumatic wounds with tissue loss in dogs.

Abstract:

Both multiple exciton generation (MEG) in semiconductor nanocrystals and singlet fission (SF) in molecular chromophores have the potential to greatly increase the power conversion efficiency of solar cells for the production of solar electricity (photovoltaics) and solar fuels (artificial photosynthesis) when used in solar photoconverters. MEG creates two or more excitons per absorbed photon, and SF produces two triplet states from a single singlet state. In both cases, multiple charge carriers from a single absorbed photon can be extracted from the cell and used to create higher power conversion efficiencies for a photovoltaic cell or a cell that produces solar fuels, like hydrogen from water splitting or reduced carbon fuels from carbon dioxide and water (analogous to biological photosynthesis). The similarities and differences in the mechanisms and photoconversion cell architectures between MEG and SF are discussed.
