Photoelectric converting device

摘要

Organic photoelectric converting devices used for photovoltaic power generation or a photovoltaic power generating system has a photoelectric converting layer comprising a block copolymer constituted by at least a polymer unit having an electron-donating molecular structure and a polymer unit having an electron-accepting molecular structure. The photoelectric converting layer can suppress macro phase separation of the donor and the acceptor, leading to efficient charge separation and has excellent carrier mobility.
