Abstract
We optimized morphology of the active layer of organic solar cells based on poly(3-hexylthiophene-2,5-diyl) (P3HT) and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) bulk heterojunction. The optimization process includes a 20min solvent annealing followed by a 5min thermal annealing at 110 °C. After such a procedure a ~3% power conversion efficiency (PCE) was achieved. Adding of gold plasmonic nanoparticles (0.1wt%) resulted in external quantum efficiency improvement.
