Inverted Perovskite Photovoltaics Using Flame Spray Pyrolysis Solution Based CuAlO₂/Cu-O Hole-Selective Contact.

ABSTRACT: We present the functionalization process of a conductive and transparent CuAlO₂/Cu-O hole-transporting layer (HTL). The CuAlO₂/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 CuAlO₂/Cu-O dispersions is used for the development of CuAlO₂/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.
