Film structures with domains that form elements with complementary functions of (a) solar cells, obtained using electron-donating polyfluorene copolymer APFO-3 and electron-accepting fullerene derivative PCBM and (b) of electronic circuitries using conjugated poly(3-alkylthiophene) P3AT and dielectric polystyrene PS. 

Polymeric cathodes have been studied as cathodes in molten salt systems, mainly by Koura and Osteryoung specifically polypyrrole [161-163], polythiophene [164], polyfluorene [165,166], polyanUine [167-172] and polyanUine polystyrene sulfonate [173] were evaluated. In many cases, the cathodes have been synthesized in the ionic liquids as weU. These cathodes can be used with several anodes, even aluminum. Such systems have low to moderate specific...
