Texto completoThin-film crystalline silicon solar cells are promising candidates for future developments in the photovoltaic industry, through expected costs reductions and applications in flexible modules. To be competitive, thin-film monocrystalline silicon solar cell technology must differentiate itself from conventional ones. It is generally based on the epitaxy of high-quality layers and then on the transfer of these layers onto a mechanical support to complete the manufacture of the cell and reuse the growth substrate. The aim of this thesis is to find the technological associations that make it possible to realize high-efficiency photovoltaic cells from thin and ultra-thin layers of monocrystalline silicon. The work presented focuses on two main axes: the development and control of technological processes for the fabrication of thin-film solar cells and the optimization of high-performance thin-cell architectures.In this framework, the development of manufacturing techniques began with the development of thin-film transfer processes: low temperature laser welding technology and high temperature fast annealing welding technology. In order to increase conversion efficiency, we have developed surface patterns using the nano-photonics concepts to improve the absorbency of thin films. With an interferential lithography at 266 nm and dry etching by RIE and wet etching by TMAH (Tetramethylammonium Hydroxide), we can produce high-performance photonic crystals on epitaxial layers of silicon. Finally, we were able to design optimized architectures of thin solar cells with homo-junction of silicon and hetero-junction amorphous silicon / crystalline silicon more efficient electrically, thanks to electro-optical simulation tools. Our theoretical approach has also led us to explain the electrical phenomena specific to thin films, and to demonstrate the full potential of thin photovoltaic cells made of monocrystalline silicon

Texto completoIn this thesis, heterojunction interface behavior, grain growth process and alternative buffer layer of Sb₂Se₃ based solar cells were investigated. The absorber quality and the band alignment are identified as key parameters for reducing defect density and for facilitating the separation and the transport of photogenerated charge carriers. A strategy of Al³⁺ doping into the CdS buffer layer was introduced in Sb₂Se₃ solar cells. The band alignment and the interface quality have been significantly improved. A “spike-like” structure was obtained for the best device with an efficiency of 8.41%. Secondly, a rapid thermal annealing process has also been developed and optimized in order to improve the quality of Sb₂Se₃ absorber film with reduced defect density. The efficiency of the Sb₂Se₃ solar cells is increased to 9.03%. In addition, we have tried to replace the toxic CdS buffer layer with an environmentally friendly ZnSnO film with moreover a wider band gap. An interesting power conversion efficiency of 3.44% was achieved for the Cd-free Sb₂Se₃ thin-film solar cells

Texto completoIn the future, the world has to face up to major challenges: increasing the energy production, reducing the environmental impact, moving towards sustainability in energy, etc. Renewable energies such as photovoltaics can meet these challenges. This thesis concerns hybrid halide perovskite materials and their use in solar cells. These materials have recently attracted a lot of attention owing to their direct bandgaps, strong light absorption, large carrier diffusion lengths, tunable optoelectronic properties, and their facile and low-cost fabrication In few years, their energy conversion efficiency has rapidly increased from 3.8 % in 2009 to 22.7 % in 2017, hence approaching efficiencies of crystalline silicon based-devices which represent 90% of commercial photovoltaic cells. In the design of perovskite cells, the perovskite photoabsorber is generally sandwiched by two interfacial layers that yield selective charge collections: the hole and electron transport layers (HTM and ETM). Good quality and adapted interfacial layers are required to obtained high efficiency cells. In this thesis, both the perovskite material and the interfacial layers are investigated

Texto completoDue to their promising functional properties, ternary oxide thin films based on Vanadium have gained much research interest in photovoltaic technologies.During this work, we first studied the possibility to use the strongly correlated metal SrVO3 as a transparent conducting oxide (TCO). For this reason, we have studied the optoelectronic properties of SrVO3 under different growth conditions. Second, our study was focused on making band gap-graded design solar cells based on oxide heterostructures. LaVO3 is particularly interesting due to its optical band gap localized in the optimal range for harvesting solar light. Accordingly, the LaVO3 was synthetized on SrTiO3 substrate under different growth conditions. Optical measurements reveal that LaVO3/SrTiO3 heterostructure grown at low oxygen pressure possess a band gap of 1.18 eV in the ideal energy range for photovoltaic. Electrical properties show that the interface LaVO3/ SrTiO3 is conducting, serving as an electrical contact for solar cells. Another interest of LaVO3 is its crystalline structure offering the possibility to combine it with other structurally compatible transition metal oxides with larger band gap such as LaFeO3 (2.2 eV) in order to enhance the optical absorption at high energy. Once the optoelectronic properties have been established, the LFO/LVO heterostructure was synthetized on SrTiO3 substrate at low oxygen pressure. The physical properties of our system have been also investigated for different LaFeO3 thickness but, to date, no photoconductivity was obtained

Texto completoLa première partie de notre travail porte sur la réalisation et la caractérisation d'une cellule photovoltaïque à base du composite poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4-phenylenevinylene (MEH-PPV) et [6,6]-phenyl C61 butyric acid methyl ester (PCBM). L'insertion des couches interfaciales, le traitement de surface et l'amélioration de la morphologie de la couche active nous ont permis d'accroître significativement les performances photovoltaïques de la structure par rapport aux performances antérieures.
Les deuxième et troisième parties portent, respectivement, sur l'évaluation de nouveaux matériaux organiques dans les cellules à base de composite et sur le développement d'une nouvelle structure de cellules photovoltaïques améliorant leur stabilité.

Texto completoThis PhD thesis deals with the implementation of the epitaxial lift-off (ELO) process from an InP substrate allowing the detachment of active layers and the substrate recycling. The final target is to realize multi-junction solar cells in an economically competitive way for concentrated photovoltaic. The ELO process consists in the under-etching of a sacrificial layer inserted between the substrate and the active layers. It is well known and mastered on a GaAs substrate with the use of a sacrificial layer of AlAs with a thickness of about 5 nm. Such a layer is not usable on an InP substrate due to the high lattice mismatch between AlAs and InP. In order to adapt the ELO process to an InP substrate, this work aimed to develop a specific sacrificial layer based on an AlAs/InAlAs superlattice. Thus, it is possible to circumvent problems related to the lattice mismatch and to the strained layer growth. After optimization of growth conditions of this superlattice, using this type of sacrificial layer, we achieve a sufficient thickness and therefore a sufficient under-etching rate in order to meet the requirements of the ELO process. Then, the transfer and lift-off of thin crystalline film based InGaAs solar cells have been developed. This kind of solar cells showed performances similar to those obtained with a standard epitaxial growth on an InP substrate, or even better under concentration due to optical confinement effects. Finally, the recycling of the InP substrate carried out by a process using only two wet chemical cleaning steps made it possible to produce InP surfaces of sufficient quality to achieve a promising second epitaxial growth

Texto completoCu(In,Ga)Se2 (CIGS) thin film solar cells are a very promising technology for high efficiency energy conversion. Several techniques are used to synthesize CIGS absorbers. Magnetron reactive sputtering is an attractive deposition technique for depositing CIGS absorbers because of its potential for providing uniform coatings over large areas, thus offering the possibility for more competitive industrial scale-up. The objective of this work is to develop and optimize a hybrid alternative co-sputtering/evaporation CIGS deposition process. To meet this goal, various studies have been conducted to ensure control of the various deposition parameters. Initially, plasma was studied with Optical Emission Spectroscopy in order to establish correlations between plasma species and thin film composition, structure and morphology. This has allowed to establish in-situ calibration curves for monitoring the deposited layers composition and their homogeneity, and to determine the existence of different sputtering modes, linked to the selenium evaporation temperature. Then, different CIGS absorbers were synthesized with the stabilized hybrid process. These absorbers were deposited in one and three stages to analyze the influence of composition gradients on their morphological, structural and optoelectronic properties. A CIGS absorber giving a maximum conversion efficiency of 10.4 % was fabricated with a one step process. A 9.3 % efficiency solar cell was obtained with a three-stage deposition process
