Scientists Fix a Hidden Flaw in Perovskite Solar Cells With Tiny Crystal Seeds

Tiny crystal “seeds” could solve a hidden flaw in perovskite solar cells—unlocking high efficiency at larger scales. Traditional perovskite solar cells (PSCs) are built with the electron transport layer underneath the perovskite light-absorbing layer and the hole transport layer on top. While this design has delivered strong performance in laboratories, it faces challenges when scaled […] Read More
