Abstract

Abstract : In this research, electrodeposited Cu2 O is introduced as a hole-transport layer (HTL) in inverse perovskite (PVK) solar cells, by which the power conversion efficiency of 2.14% has been achieved. Appropriate energy levels for carriers transferring in ITO/Cu2 O/PVK/PCBM/Au cell configuration had been evaluated by Mott-Schottky; however, energy dispersive X-ray spectroscopy indicated some chemical reactions happened between layers. Ambient Kelvin Probe has been used to evaluate the work function of Cu2 O and Cu2 O deposited by PVK. The dissimilar work function for these two layers provoked some chemical reactions. Based on our results, the probable occurrence of discarded interfacial chemical reactions significantly affects solar cell performance.
