ABSTRACT: Perovskite solar cells are the subject of numerous studies. These studies concern among others the optimal thickness and doping of the perovskite and the choice of charge transport materials. This work investigates the SCAPS simulation of a perovskite solar cell using separately SPIRO-OMeTAD, PEDOT:PSS, P3HT and Cu2O as the hole transport layer. The cell is completed with hematite as an electron transport layer. Thus, the simulation shows that the optimal thickness of the perovskite is around 700 nm and the optimal doping is 1020 cm−3. Regarding the hole transport layers, we designed the influence of the thickness between 5 nm and 20 nm of these layers. It appears that over this range of thickness, the four HTLs contribute to obtaining almost equal performance of the cell with 35.21%, the maximum efficiency (PCE) obtained with PEDOT:PSS and 35.16%, the minimum PCE obtained with SPIRO-OMeTAD. However, this efficiency can reach over 42% by doping the perovskite layer at 1020 cm−3 NA. These promising results open the way to experimental trials to determine the real limits for this cell.
