Inverted Perovskite Photovoltaics using Flame Spray Pyrolysis Solution based CuAlO2/Cu-O Hole Selective Contact
2019
We present the functionalization process of a conductive and transparent copper aluminum oxide, copper oxide alloy. The copper aluminum oxide, copper oxide powders were developed by flame spray pyrolysis and their stabilized dispersions were treated by sonication and centrifugation methods. We show that when the supernatant part of the treated copper aluminum oxide, copper oxide dispersions is used for the development of hole transporting layers the corresponding inverted perovskite solar cells show improved functionality and power conversion efficiency with negligible hysteresis effect.
