New record efficiency for flexible perovskite solar cells
Porous planar electron transport layer boosts power conversion efficiency in flexible perovskite solar cells to 20.7%
Scientists have developed a material for flexible perovskite solar cells that uses sunlight-generated electrons more effectively, obtaining a new record efficiency of 20.7%. The material includes a porous planar electron transport layer that improves the interaction between its electrodes and perovskite layer, increasing performance to nudge the concept closer to real-world applications.
