摘要：
The fullerene derivatives containing cross-linkable styryl or epoxy groups were synthesized and used to fabricate high efficient bulk heterojunction PSCs. The cross-linkable fullerene derivatives are also used to fix the morphology of bulk heterojunction (BHJ) layer so as to improve the stability of PSCs. A new cathodic buffer layer consisting of a cross -linked [6,6]-phenyl-C61-butyric styryl dendron ester (C-PCBSD) matrix and an ionic FPI dopant was developed. The incorporation of FPI can improve the electron mobility via an anion induced charge transfer mechanism while maintaining the solvent-resistant property of the crosslinked layer. The ZnO combined with C-PCBSD/FPI layer can effectively and universally improve the performance of bulk-heterojunction polymer solar cells (BHJPSCs), planar heterojunction polymer solar cells and perovskite solar cells (OMPSCs). Furthermore, the insertion of C-PCBSD/FPI layer can improve the thermal stability of the device by preventing the residue moisture in ZnO from diffusing into the CH3NH3PbI3 layer in OMPSCs.
