Abstract :
Abstract: Perovskite solar cells have become an attractive subject in the solar energy
device area. During ten years of development, the energy conversion efficiency has been
improved from 2.2% to more than 22%, and it still has a very good potential for further
enhancement. In this paper, a numerical model of the perovskite solar cell with the
structure of glass/ FTO/ TiO2/ H3NH3PbI3/ HTM/Au by using Silvaco Atlas software is
presented. The effect of hole transport material characteristics, including hole mobility
and band gap offset of organic and inorganic HTM layers such as Spiro-MOeTAD, CuO
and Cu2O on the performance of PSCs are investigated. The simulation results reveal that
with 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 like
CuO and Cu2O as hole transport layer, than by using Spiro-MOeTAD, particularly the
efficiency reaches 22.12% when Cu2O is used.
