Implication

This analysis demonstrates energy level alignment in perovskite solar cells, suggesting improved efficiency.

Abstract

Hole-collecting monolayers (HCMs) have attracted considerable attention in p-i-n (inverted structure) perovskite solar cells. Although HCMs show superior performance to widely used polymers, there is confusion in the understanding of...
