Photovoltaic cell

摘要

Photovoltaic cell comprises a photoactive layer (4) made up of a conjugated polymer component as electron donor and a fullerene component as an electron acceptor. Both components and their mixed phases in sections of the photoactive layer have an average largest grain size of less than 500 nm. An independent claim is also included for a process for the production of a photovoltaic cell comprising applying a mixture of the conjugated polymer component and the fullerene component with a solvent to a carrier layer (1) provided with an electrode layer (2). The solvent is chlorobenzene.
