Towards high performance inverted polymer solar cells

[摘要] Attempts to develop inverted polymer solar cells (PSCs) as required for achieving high efficiency and good stability have, however, met with limited success. Here, we report that a high efficiency of 8.4% was achieved for inverted PSCs. This high efficiency was obtained through interfacial engineering of solution-processed electron extraction layer, leading to facilitate electron transport and suppress bimolecular recombination. These results provided an important progress for solution-processed PSCs, and demonstrated that the inverted PSCs are comparable with the conventional PSCs.
