Full textThe public mind is aware of electronics drawbacks, the costs of development and production are important and the environmental impact can be denied. In order to solve those downsides, the organic electronics is studied and developed. This electronics have been introduced with the discovery of conductive polymers by the Nobel prices of chemistry from the year 2000, Alan J. Heeger, Alan G. MacDiarmid et Hideki Shirakawa. Since then, this technology has been widely developed and nowadays OLED (Organic Light Emitting Diode) screens as well as others devices like MEMS (Micro ElectroMechanical System), systems connecting electronics and mechanics, are commercialized. Those organic MEMS are more and more studied and developed due to a better flexibility of the organic semiconductors compared to the inorganic ones. However, even if the research on the polymer mechanics and semiconductor electronics is advanced, the electromechanical interaction of the organic semiconductors is poorly studied. Nevertheless, it is necessary to understand this interaction in order to develop the flexible electronics of tomorrow. Thus, this work has been focused on investigating the electromechanical interaction inside the organic semiconductors and developing tools/methods usable to study with ease new molecules. To better understand the electromechanical interaction between molecular structure and electrical response, the semiconductors are shaped into single crystals, in order to study a perfect molecular layout, without imperfections, in the three space dimensions. Hence, in the first instance, the influence of the molecular structure on the charge mobility was studied on rubrene. Even if is commonly assumed that the variation of the intermolecular distance causes the mobility changes inside rubrene, it turns out that this electrical variation is due to a reorganization of the molecules and variations of multiples inter/intramolecular parameters which modify the electronic coupling. In the second instance, the electromechanical response of air-gap transistors based on rubrene has been studied. In this more complicated systems, multiple parameters variate during the deflection. With the use of Gauge factor, it is possible to prove that the electromechanical response of those systems depends mainly on the mechanical and electrical modification of the interface electrodes/semiconductor. The high improvement of the electrical response of those air-gap transistors has been used to fabricate pressure sensors capable to detect forces as small as 230 nN. Finally, the methods developed during the previous works have been used to start the synthesis and characterization of hybrid perovskite transistors in order to study the electromechanical interaction of those emerging materials

Full textThis study focuses on organic semiconductors based on perylene derivatives for electronic applications, especially in the fabrication of organic field effect transistors (OFETs). The main objective is the synthesis of perylene based molecules, taking advantage of its specificities, and their electrical characterization through the realization of test transistors. First, various perylene derivative architectures were achieved by direct reaction from the tetracarboxylic dianhydride acid pérylène or with by direct functionalization of the core. Then, using electrochemical technics, we determined the energy levels of our molecules. The knowledge of these levels is essential for therealization of high performance transistors. Finally, test transistors were fabricated using some perylene based semiconductors, and their output current/voltage characteristics were measured in order to evaluate the molecule electrical dehavior

Full textAt a time when new technologies emerge every day, a specific domain stands out: the organic electronic. Through its low cost processing or even its utility, the organic electronic constitutes a very promising future.In order to improve the fabrication process and the lifetime of the devices, the work of this thesis was focused on the synthesis of copolymers with various architectures based on poly(3-hexylthiophene) (P3HT). After a first part where main issues and objectives are presented, the synthesis of different P3HT-based precursors is described in a part which could be considered as the heart of these works. Starting with appropriated precursors, the optimization of rod-coil diblock copolymer synthesis was performed following a strategy designed specifically for organic electronic application. Moreover, the precursors were used for the conception of new semi-conducting materials with a variety of architectures, such as graft and star copolymers. Finally, the last part deals with the integration of the P3HT-b-Poly(4-vinylpyridine) copolymer into organic solar cell as an additive of the active layer. This approach turns out to be powerful, especially allowing decreasing the time and the energy cost by avoiding the key step of the fabrication process of those devices, the annealing step

Full textThe aim of this thesis is to develop efficient semi-conducting organic materials for organic photovoltaics. This work is focuses on the optimization of electron-donor organic semiconductors for the preparation of bulk heterojunction devices, in blend with a fullerene derivative used as electron-acceptor material. More specifically, it is to perform a systematic optimization study of two reference families (macromolecular and molecular respectively) from the laboratory, which have already led to interesting photovoltaic performances. For this, we followed a structured and systematic approach targeting the most relevant chemical parameters to be varied. To determine the properties of new materials synthesized, spectroscopic, electrochemical, structural, charge transport and photovoltaic characterizations were systematically made

Full textThe current context of strong growth in energy demands in the world requires diversification of its production, in particular towards renewable sources while limiting as far as possible the emission of greenhouse gases. Among the most promising and abundant renewable energies is solar energy and it is evident that solar, thermal or photovoltaic energy represents a crucial issue to reduce the consumption of fossil energy. Currently 90% of the solar generators are made of crystalline silicon, which poses a problem of supply of raw material, as silicon producers did not know how to anticipate the strong expansion of the solar sector. Innovative concepts present a high potential in terms of cost of production and application, in particular organic and hybrid (organic / metal oxide) dies. In Europe, France is very active in this area of research, particularly with regard to the use of new organic nanostructured materials or hybrid structures. This is why Disasolar, a French start-up specializing in flexible photovoltaics, wants to develop this activity by developing flexible solar modules by inkjet printing. The objectives of this thesis are to study new printable interface materials and to evaluate the effect of nanoparticle size on the topology and performance of devices. And secondly, the study will focus on the printing of interface materials and the stability of organic solar cells

Full textOrganic solar cells are often called “polymer” solar cells. This term comes from the fact that the active layer of such solar cells have been widely made with a donor polymer. The use of polymer inthe active layer gives interesting filming properties that can be used to produce these solar cells industrially with a high speed printing process. Yet, another type of donor materials exists: the small molecules. Deposited by thermal evaporation, this type of materials can allow to reach high efficiency solar cells. Because of their poor filming properties, small molecules were not a good candidate for an industrialization using high speed printing. However, in 2012 several solution processable small molecules were proven particularly promising by demonstrating high efficiency at a laboratory scale.These encouraging results let imagine that it could be possible to produce organic solar cells with such materials. This PhD work has been done in collaboration with ARMOR, a company highly implied in the commercialization of organic solar cells, in order to evaluate if small molecules materials could be use dindustrially with a high speed printing process. The p-DTS(FBTTh2)2 has been chosen for this study. It has been shown that it is possible to reach efficiencies as high as 2 % with such a material, using non toxicsolvents and by making the solar cell in the air with a Doctor Blade. Nevertheless, the industrialization ofthe p-DTS(FBTTh2)2 has not been pursued due to the rapid degradation of this molecule in the air. This work presents a method that can be used to evaluate the industrialization of other efficient small molecules

Full textIn the field of organic photovoltaic, conjugated electron donor polymers with improved optoelectronic properties are highly needed. Therefore, that research work is focused on the design and investigation of a new family of donor-acceptor alternating low band-gap copolymers, using 2,1,3-benzothiadiazole as electron-deficient unit, and thieno[3,2-b]thiophene and alkylthiophenes moieties as electron-rich units. By the inclusion of fused thiophene rings we intend to enhance the hole carrier properties. Various alkyl side-chains are introduced onto different positions along the conjugated backbone in order to reach efficient solubility in common organic solvents and simultaneously allow investigations of structure/properties relationships. We have also studied the effect of conjugation length and planarity on the optoelectronic properties. In the first section we discuss the synthesis methods of the monomers which involve several organic and organometallic reactions. Then, the copolymers have been synthesized by Stille or Suzuki cross coupling polycondensation. In the second part, special focus is devoted on how modifications in the conjugated backbone length and conformation (side chains length and positioning, coplanar units) are affecting the related material properties (electrochemical, UV-vis absorption, microstructure and charge carrier mobility). Finally, we have elaborated bulk heterojunction solar cells based on copolymer:C60-PCBM blend and correlated the OPV device performances with the optoelectronic properties of the polymers

Full textOrganic solar cells appear as a promising technology to meet future energy requirements, owing to their low production costs, their great flexibility and their ability to be integrated into light devices. Currently, they exhibit modest performances in photoconversion, thus new active molecules with optimized structural properties need to be developed. This work comes in that aim: on the basis of theoretical calculations with density functional theory, new organic semiconductors have been designed and synthesized. For this, the more economical and cleaner syntheses techniques have been employed. Thus, the coupling of the benzothiadiazole with thiophene carboxhaldehyde via direct heteroarylation without additive nor ligand is performed with success for the first time. According to green chemistry techniques, five molecules are thus isolated in only two steps. The study of their optical and electronic properties by means of different spectroscopic techniques (UV/vis, fluorescence) and electrochemistry, of their thermal properties, and of their ability to self-organize have revealed their promising abilities for use in organic photovoltaics. A series of small molecules based on dithienosilole (DTS) core have also been designed via DFT computations. The calculations show their considerable low bandgap. Their syntheses have been conducted. It anticipates their promising potential for organic photovoltaic applications. Finally, a purely theoretical work has been completed on molecules derived from boron subphthalocyanines. The calculations predict interesting electronic properties for these new materials that may lead to promising performances in organic photovoltaics, paving the way for innovative materials
