| Abstract: | Two perylene bisimides based non-fullerene small molecules, H-DIPBI and B-DIPBI, are applied into inverted planar heterojunction perovskite solar cells. The power conversion efficiency up to 11.6% has been achieved for device with B-DIPBI, indicating that non-fullerene acceptor can function as the electron transport layer to replace PCBM in perovskite solar cells. |
