Abstract
A method can be used to produce a photovoltaic cell. A first transparent electrically conductive layer is deposited over the substrate. A metal oxide layer is deposited over a surface of the electrically conductive layer facing away from the substrate. The metal oxide layer is subdivided into a number of metal particles by a thermal decomposition. A second transparent electrically conductive layer is deposited over the metal particles.
