generation in binary and ternary blend organic solar cells were studied with
photoluminescence measurements. Specifically the influence of adding the polyfluorene
copolymer poly (9, 9-dioctylfluorene)-2, 7-diyl-alt-[4, 7-bis (3-hexylthiophen-5-yl) 2, 1, 3-
benzoth iadiazole]-2′, 2 ″-diyl)(F8TBT) to poly (3-hexylthiophene)(P3HT):[6, 6]-phenyl-C
61-butyric acid methyl ester (PCBM) blends was investigated. This third constituent (F8TBT) …
