Fabrication and TCAD Simulation of TiO2 / ZnO Nanorods Electron Transport Layer based CH3NH3PbI3 Perovskite Solar Cell

Abstract

The worldwide increase in energy consumption has motivated scientists to explore the potential of solar energy. At present, solar energy harvesting is carried out mostly (more than 90%) by the inorganic crystalline silicon (Si) solar cells. Moreover, Si-based solar cells are now approaching their maximum theoretical limiting efficiency of ~29.43%. The latest advancements in technology and materials have led to the development of novel photosensitive materials that enabled the fabrication of low cost and highly efficient photovoltaic devices. The state of the art growth in various perovskite materials like inorganic (CsPbX3: X=I, Cl, Br) and hybrid (ABX3; A= organic compound, B= inorganic compound, and X= halides) have attracted huge interest among the researchers. Recently, methylammonium lead halides (CH3NH3PbX3) have shown highly encouraging photosensitive for photovoltaic application, which gained immense research attention since its discovery and has boosted hopes for new photovoltaic technologies.
