Abstract
The disclosed invention consists of high efficiency organic solar cells (0) with a multi layer structure, consisting of cathode layer (1), organic acceptor layer (2), organic donor layer (3), conductive anode layer (4) and a substrate layer (5), where an adjustment of electronic levels of separated layers is achieved by introduction of at least one intermediate matching layer (x). In conjunction with the selection of active layer (3) consisting of cyanine dyes with appropriate counterions (e.g. hexafluorophosphate), high performance organic solar cells with long lifetimes can be fabricated with a fast and simple manufacturing method.
