Highly Stable and Enhanced Performance of p-i-n Perovskite Solar Cells via Cuprous Oxide Hole-Transport Layers.

ABSTRACT: Solar light is a renewable source of energy that can be used and transformed into electricity using clean energy technology. In this study, we used direct current magnetron sputtering (DCMS) to sputter p-type cuprous oxide (Cu₂O) films with different oxygen flow rates (f_O2) as hole-transport layers (HTLs) for perovskite solar cells (PSCs). The PSC device with the structure of ITO/Cu₂O/perovskite/[6,6]-phenyl-C₆₁-butyric acid methyl ester (PC₆₁BM)/bathocuproine (BCP)/Ag showed a power conversion efficiency (PCE) of 7.91%. Subsequently, a high-power impulse magnetron sputtering (HiPIMS) Cu₂O film was embedded and promoted the device performance to 10.29%. As HiPIMS has a high ionization rate, it can create higher density films
