Abstract

High Resolution Image Download MS PowerPoint Slide 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.
