We report polymer solar cells with a polymer blend nanolayer (film) that consists of two electron-donating polymers and one electron-accepting polymer. Regioregular poly(3-hexylthiophene) (P3HT) and poly[2-methoxy-5-(3',7'-dimethyloctyloxy)-1,4-phenylenevinylene] (MDMO-PPV) were employed as electron-donating polymers, whilst poly(9,9-dioctylfluorene-co-benzothiadiazole) (F8BT) was used as an electron-accepting polymer. Two kinds of solvent and film thickness were applied to examine their effect on the device characteristics. Results showed that the device performance was better when p-xylene was used as a solvent, whilst thicker blend films exhibited better power conversion efficiency. A nanohole morphology found in the blend film made using chlorobenzene, compared to the blend film made using p-xylene, was assumed to be responsible for the relatively poor device performance in spite of higher absorption in the longer wavelengths. Still low efficiency of present devices was attributed to the existence of charge blocking resistances in the bulk polymer nanolayer.

Ternary blend polymer solar cells combining two electron-donor polymers, 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) and poly[2,5-bis(3-dodecylthiophen-2-yl)thieno[3,2-b]thiophene] (pBTTT) and [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM), as electron-acceptor, were fabricated. The power conversion efficiency of the ternary cells was enhanced by 18%, with respect to the reference binary cells, for a blend composition with 25% (wt%) of pBTTT in the polymers content. The optimized device performance was related to the blend morphology, nonrevealing pBTTT aggregates, and improved charge extraction within the device.
