Conception de contacts oxydes et de pérovskites à cations mixtes pour des cellules solaires hautement efficaces

Abstract : Perovskite-based solar cells (PSCs) have emerged as the most promising new generation of photovoltaic technology.Organometal trihalide perovskite solar cells (PSC) have aroused widespread academic and commercial interests due to rapid increase in efficiency, which has boosted from 3.8%4 in 2009 to 20.1%5 in 2014. These great achievements are mainly attributed to the unique characteristics of perovskite materials, such as low cost, high photo-to-electric conversion efficiency, high light absorption properties, direct bandgap, high charge- carrier mobility and long electron-hole exciton transport distance (more than 1 µm). 6-8 Perovskite material is soluble, which makes it quite easy and cheap to prepare perovskite solar cells.
