Abstract:
Abstract: Perovskite solar cells have become an attractive subject in the solar energydevice area. During ten years of development, the energy conversion efficiency has beenimproved from ۲.۲% to more than ۲۲%, and it still has a very good potential for furtherenhancement. In this paper, a numerical model of the perovskite solar cell with thestructure of glass/ FTO/ TiO۲/ H۳NH۳PbI۳/ HTM/Au by using Silvaco Atlas software ispresented. The effect of hole transport material characteristics, including hole mobilityand band gap offset of organic and inorganic HTM layers such as Spiro-MOeTAD, CuOand Cu۲O on the performance of PSCs are investigated. The simulation results reveal thatwith increase of hole mobility in hole transport layer, the cell efficiency is increases.Meanwhile, the solar cell exhibits a better performance by using inorganic materials likeCuO and Cu۲O as hole transport layer, than by using Spiro-MOeTAD, particularly theefficiency reaches ۲۲.۱۲% when Cu۲O is used.
