We report that device performance of organic solar cells consisting of zinc phthalocyanine and fullerene (C(60)) can be enhanced by insertion of a perylene derivative interfacial layer between fullerene and bathocuproine (BCP) exciton blocking layer (EBL). The morphology of the BCP is influenced by the underlying N,N'-dihexyl-perylene-3,4,9,10-bis(dicarboximide) (PTCDI-C6), which promotes migration of the cathode metal into the BCP layer. Insertion of a PTCDI-C6 layer between fullerene and BCP layers enhances the power conversion efficiency to 2.5%, an improvement of 32% over devices without PTCDI-C6 layer. The enhancement in device performance by insertion of PTCDI-C6 is attributed to a reduction in series resistance due to promoted metal migration into BCP and optimized optical interference effects in multilayered devices.
我们报告说，通过在富勒烯和苯并二噻吩（BCP）激子阻挡层（EBL）之间插入苝衍生物界面层，可以提高由锌酞菁和富勒烯（C（60））组成的有机太阳能电池的器件性能。BCP 的形态受到底层 N，N'-二己基-苝-3,4,9,10-双（二羧酸酰亚胺）（PTCDI-C6）的影响，这促进了阴极金属向 BCP 层的迁移。在富勒烯和 BCP 层之间插入 PTCDI-C6 层将功率转换效率提高到 2.5％，比没有 PTCDI-C6 层的器件提高了 32％。通过插入 PTCDI-C6 提高器件性能归因于由于促进了金属向 BCP 的迁移而降低了串联电阻，以及多层器件中优化的光学干涉效应。
