Abstract

we investigate the potential and stability of perovskite(MaPbI3) as the hole-selective contact materials for silicon solar cells because perovskite has excellent carrier transport properties for both electrons and holes. We have overcome the problem of forming a continuous perovskite thin film on silicon due to low surface energy by engineering the silicon surface roughness and native oxide. As a result, the short-circuit current density (Jsc) of the device with the perovskite layer increases by 0.6mA/cm2 from 27.73 to 28.32 mA/cm2 and the open-circuit voltage (Voc) increases by 5mV from 517.36 to 512.50 mV, reaching a power conversion efficiency of 10.53%. The solar cell with the perovskite(MaPbI3) hole selective layer exhibits better performance than the reference counterpart. Future work will be focused on tuning the composition of the PbBr2 and PbI2 to modify the work function and enlarge the hole selectivity.
