Comprehensive design analysis of electron transmission nanostructured layers of heterojunction perovskite solar cells
Abstract
A comprehensive design and optimization analysis of different nanostructured electron transmission layers for perovskite solar cells is performed. COMSOL Multiphysics commercial package is used to model and simulate a single layer, bi-layer, and a sandwich structures that can be used as electron transport layers. Different materials namely; ZnO, TiO2, and WO3 nanostructured layers are used in the suggested structures. The study revealed the best materials, structure, and thicknesses to be used in the implementation of the electron transport layer. From this design, it is found that a single layer of ZnO with thickness (∼50 nm) is the best option. On the other hand, the sandwich structure of TiO2/ZnO/TiO2 was the least efficient to transmit light to the perovskite layer.
