Sol–gel processible organosilicate material based on dialkylviologen (1,1-(bis-trimethoxysilane)-[4,4′]bipyridium dibromide (bis-trimethoxypropylsilane)-yl-viologen, PV-Si) was synthesized and used as an interfacial layer material for polymer solar cells based on poly(3-hexylthiophene): [6,6]-phenyl-C 61 -butyric acid methyl ester (P3HT:PCBM). PV-Si is very good soluble in polar protic solvents...
The power conversion efficiency (PCE) of bulk hetero-junction type polymer solar cells (PSCs) based on poly(3-hexylthiophene) and (6,6)-phenyl-C61-butyric acid methyl ester can be enhanced by insertion of the thin layer of phenothiazine (PT)-based conjugated polymer electrolytes (CPEs), poly{10-[4-(N,N,N-trimethylammonium)butyl]-10H-phenothiazine} bromide (PHPT) and poly{10-butyl-10H-phenothiazine-alt-10-[4-(N,N,N-trimethylammonium)butyl]-10H-phenothiazine}...
