Photovoltaic properties of nanocrystalline CuInS2/methanofullerene solar cells
First attempts were made to use nanocrystalline CuInS2 with the fullerene derivatives to form flat interface donor-acceptor heterojunction solar cells. We synthesized nanocrystalline CuInS2 in a colloidal route, the particle surfaces were shielded by an organic surfactant. We present photovoltaic data ofnanocrystalline CuInS2 Schottky diodes in comparison with heterojunctions of CuInS2 and methanofullerene derivatives. Flat interface heterojunction solar cells show significant better photovoltaic response than solar cells consist of nanocrystalline CuInS2 single-layers. In comparison to the single-layers, anincrease of cell efficiency about factor 25 is received.
