Plastic Solar Cells

摘要

Recent developments in conjugated-polymer-based photovoltaic elements are reviewed. The photophysics of such photoactive devices is based on the photo-induced charge transfer form donor-type semiconducting conjugated polymers to acceptor-type conjugated polymers or acceptor molecules such as Buckmisnterfullerence, C_60. This photo-induced charge transfer is reversible, ultrafast (with 100 fs) with a quantum efficiency approaching unity, and the charge-separated state is metastable (up to milliseconds at 80 K).
