Alloy Acceptor: Superior Alternative to PCBM toward Efficient and Stable Organic Solar Cells
The alloy acceptor (indene-C-60 bis-adduct (ICBA)/[6,6]-phenyl-C-71-butyric acid-methylester (PC71BM)) is employed to replace the widely used fullerene acceptor (PC71BM) in organic solar cells based on five different polymer donors, which exhibit a higher efficiency and much better device stability than the PC71BM counterpart.
