Abstract: In this article, we have evaluated the performance of inverted organic solar cells (OSCs) fabricated under ambient air and inert environment. Here, poly([4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b′]dithiophene-2,6-diyl]{3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) (PTB7) donor with [6,6]-phenyl C70-butyric acid methyl ester (PC71BM) acceptor were employed… read more here.
