Perovskite solar cell built with slot die coating achieves 19.17% efficiency

A team from Jeonbuk National University in South Korea used slot die coating (SDC) to produce uniform high-quality perovskite films, which they used in a perovskite solar cell that achieved 19. 17% efficiency and lab cell-sized modules that achieved 17. 42% efficiency. A team from Jeonbuk National University in South Korea investigated the use of slot die coating (SDC) to make uniform high-quality perovskite films as a step towards large-area perovskite device manufacturing. The scientists found that SDC increased the roughness of the hole transport layer (HTL) interface, which improved the wettability ...
