Abstract |
Copper based inorganic hole transporting material (HTM) employing lead halide perovskite solar cells (PSCs) was developed by aerosol spray deposition in this work with high efficiency and remarkable long-term stability. We developed a reproducible method to deposit CuSCN layer on the CH3NH3PbI3 layer by a simple aerosol spray deposition technique, which does not appreciably damage the underlying CH3NH3PbI3 layer. Also we obtained high crystallinity CuSCN film on the CH3NH3PbI3 layer with enhanced interface which leads to higher VOC and FF. The fabricated PSC with ~50 nm-thick pristine CuSCN layer exhibited the photovoltaic conversion efficiency (PCE) of 17.10% with JSC of 23.10 mA/cm2, VOC of 1,013 mV and FF of 0.731. Comparing to the PSC employing Spiro-OMeTAD, its JSC is comparetively higher, suggesting that CuSCN is superior to Spiro-OMeTAD in transporting the holes, although its VOC is appreciably lower presumably due to the absence of additives in the CuSCN-based HTM. Furthermore, PSCs employing the pristine CuSCN demonstrate a remarkable long-term stability at ambient condition: PCE was decreased by only 5.8% after 100 days. |
