题目:Crosslinkable fullerene derivatives for thermally stable polymer and perovskite solar cells

时间:925日(周五)上午10

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.
