Design and Optimization of Nanostructured UV-Filters for Efficient and Stable Perovskite Solar Cells

摘要： The Design and optimization of a nanostructured UV-light filters, for perovskite solar cells, significantly improves the stability of perovskite solar cells in the UV-light region, where the UV-severe instability issues found in the degradation of perovskite materials under UV-light by using COMSOL Multiphysics commercial package is performed. This design is crucial for under a 50 nm bi-composite layer of TiO2 and WO3 nanoparticles. The proposed structure of TiO2, WO3, and ZnO. It is noted that the most efficient structure is a 10 nm TiO2 thin film illumination. The suggested structure is a thin film of TiO2 in conjunction with nanoparticles layers blocking properties are enhanced by about 75% compared with the solar cell without using the suggested filter design.
