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

By Chinese Academy of Sciences - Published on 27 February 2026

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 [...]
