Inverted Perovskite Photovoltaics Using Flame Spray Pyrolysis Solution Based CuAlO(2)/Cu–O Hole-Selective Contact

[Image: see text] We present the functionalization process of a conductive and transparent CuAlO(2)/Cu–O hole-transporting layer (HTL). The CuAlO(2)/Cu–O powders were developed by flame spray pyrolysis and their stabilized dispersions were treated by sonication and centrifugation methods. We show th...

Sumario:[Image: see text] We present the functionalization process of a conductive and transparent CuAlO(2)/Cu–O hole-transporting layer (HTL). The CuAlO(2)/Cu–O 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 CuAlO(2)/Cu–O dispersions is used for the development of CuAlO(2)/Cu–O HTLs the corresponding inverted perovskite-based solar cells show improved functionality and power conversion efficiency of up to 16.3% with negligible hysteresis effect.
