Organic Photovoltaic / Organic Solar Cell
Organic photovoltaics use organic materials to generate electricity from light. Because of their flexibility, light weight, and high performance in low or variable light situations, organic photovoltaics may be used as sources of electricity for portable electronic devices, or in a variety of markets such as building integrated systems, signage, packaging and smart fabrics. The primary photovoltaic device mechanism that has been utilized is that of photoinduced charge transfer between an electron donor and acceptor. Typical solar cells use organic polymers or small molecules for light absorbtion and charge transport to produce electricity from sunlight by photovoltaic effect.
