Abstract

Usually, there are some discrepancies between simulations and measurements in Perovskite solar cells (PSCs). This is partially due to ignoring defects in transporting layers. In this work, realistic simulations were undertaken to study the effects of bulk defects in cuprous oxide (Cu2O), the Hole Transporting Layer (HTL). Firstly, two different cell absorbers namely, the Br doped formamidinium tin iodide (Br-FASnI3) and the methylammonium lead iodide (MAPbI3), were considered. The thicknesses of the absorber, the electron transporting layer (ETL) (SnO2), and the HTL (Cu2O), were optimized, leading to 24.34% and 20.30% power conversion efficiencies (PCE) for MAPbI3 and Br-FASnI3, respectively. Furthermore, ETL doped antimony (Sb–SnO2) showed better performance in MAPbI3-based PSCs while multiple functional group organic molecule of 3-(formamidinothio)-1-propanesulfonic acid (FTPS) as additive to SnO2 (FTPS–doped SnO2) was better for Br-FASnI3-based solar cells. Secondly, the impact of defects in Cu2O was considered. In Br-FASnI3 devices, the acceptors largely influence the PCE. So, by enhancing the open circuit voltage VOC, especially the shallower level (0.16 eV), the PCE reached 27.97%. Their effect is less pronounced when they are deeper (1.3 eV). As for the donors, they tend to reduce VOC. On the other hand, because in the MAPbI3-based solar cell the ETL is already thin, the photogenerated electrons will be almost directly extracted, which reduces the collected current density JSC and therefore the PCE. As for the HTL donor traps, their effect is similar to that in the Br-FASnI3 solar cell, where they drastically reduce the PSC performance via the recombination process.
