Solar semiconducting polymers

Ultrafast photoinduced electron transfer in semiconducting polymers mixed with controlled amounts of acceptors this phenomenon has opened the way to a variety of applications including high-sensitivity plastic photodiodes, and efficient plastic solar cells ... 

The choice of the D/A pair (energetics determine the open-circuit potential). In addition, the bandgap of the semiconducting polymer should be chosen to ensure efficient harvesting of the solar spectrum.

The first solid-state dye-sensitized heterojunction of Ti02 and a semiconducting polymer was reported by Murakoshi and coworkers [19, 7]. They formed a solid-state heterojunction by photoelec-trochemical polymerization of pyrrole into a nanoporous Ti02 film, sensitized with Ru(dcbpy)2(SCN)2. Direct contact of polypyrrole and the FTO back contact was suppressed by electrodeposition of a thin Ti02 film before the adsorption of the dye onto the nanocrystalline Ti02 electrode. The doping density of the polymer was controlled electrochemically. Solar energy conversion efficiencies were somewhat...
