Polymers are an exciting prospect for use in solar cells because their manufacture is cheap, easily processed at low temperatures and can be scaled up for industrial production. A key drawback is their relatively low power conversion efficiency. A better understanding of light absorption and charge transfer dynamics in these materials is needed for their efficiency to match that of the more conventional silicon-based devices.
