超过18%效率!光交联聚酯助力高效柔性钙钛矿太阳能电池
低温制备给了柔性器件钙钛矿电池很大机遇,然而柔性器件的机械稳定性一直存在问题。苏州大学王照奎,廖良生联合柏林亥姆霍兹材料与能源中心Antonio Abate团队采用光交联的聚酯(C-PCBOD)用于改善MAPbI3钙钛矿膜的机械稳定性。此外,证明了C-PCBOD可以钝化钙钛矿的晶界和减少陷阱态,并增强了MAPbI3的稳定性。因此,在刚性和柔性基材上制备MAPbI3钙钛矿太阳能电池,效率分别为20.4%和18.1%。 Li, M., Yang, Y.‐G., Wang, Z.‐K., Kang, T., Wang, Q., Turren‐Cruz, S.‐H., Gao, X.‐Y., Hsu, C.‐S., Liao, L.‐S., Abate, A., Perovskite Grains Embraced in a Soft Fullerene Network Make Highly Efficient Flexible Solar Cells with Superior Mechanical Stability.
