Abstract A Comprehensive Electrical modeling analysis of Heterojunction Perovskite Solar Cells by using different nanostructures Electron transport layers is accomplished. COMSOL Multiphysics commercial package was used to design and analyze an optoelectronic model of different device structures of the electron transport layers of Perovskite Solar Cell; mainly single layer, bi-layer, and sandwich structures. This was achieved by investigating three metal oxide materials namely: ZnO, TiO2, and WO3. The results show an enhancement in the device performance by using the sandwich structure of TiO2/ZnO/TiO2 at thicknesses of (10/50/20) nm with a power conversion efficiency of 19.26 %. While the study revealed that the least efficient electron transport layer is a single tungsten oxide layer at a thickness ∼ 10 nm) with a power conversion efficiency of 12.14 %.
