Low-bandgap conjugated polymer for high efficient photovoltaic applications.
We investigate the morphological and performance of organic photovoltaics based on blended films of alternating poly(thiophene-phenylene-thiophene) and [6,6]-phenyl-C(71)-butyric acid methyl ester (PC(71)BM). The resulting fine-scale phase separation leads to enhanced performance and the highest power efficiency (6.4% under AM 1.5G (100 mW cm(-2))) when we use solvent annealing process.
