US Patent 9112163 Photoactive component having a plurality of transport layer systems

A photoactive component has an electrode and an opposing electrode. The electrodes have at least one organic layer system arranged between them, also having at least two photoactive layer systems and, between the photoactive layer systems, at least two different transport layer systems have the same charge carrier type. In this case, one transport layer system matches one of the two photoactive layer systems in energy terms, while the other transport layer system is of transparent design.
