Synthèse et étude des propriétés optiques de Couches d’Oxydes métalliques et Applications photovoltaiques

Abstract

Studies carried out on transparent and conductive oxides TCO have attracted the attention of many researchers because of their various applications in the industry of microelectronics, mechanics, optoelectronics, surface treatment and especially in photovoltaics, etc. thanks to their double property, electrical conductivity and transparency in the visible. Metal oxide materials deposited in thin layers such as TiO2 and ZnO have been known for a long time. Zinc oxide (ZnO) is a material belonging to the family of transparent conductive oxides (TCO). The non-toxicity and abundance on earth of its components make it an ideal candidate as a transparent electrical contact for thin-film solar cells of amorphous and/or microcrystalline silicon. The fundamental objective of our research work is to optimize the basic component optical properties of ZnO/PVP-based solar cells and this according to an elaborate process, by sol-gel route of ZnO/PVP layers under different experimental conditions. To determine the structure characterize the deposits obtained and characterize their optical properties to optimize the parameters we produce our solar cells. Thanks to the framework agreement signed in 2022 between the Belhadj Bouchaib University and the Abou Bekr Belkaïd University of Tlemcen, the chemical preparations and optical characterizations of the thin layers deposited by the spin coating method are carried out at the level of the Materials and Renewable Energies Unit (URMER) from the University of Tlemcen.
