Abstract
The present invention relates to a process for the production of a layered body (), at least comprising the process steps: I) provision of a photoactive layer comprising a material having a perovskite type crystal structure; II) superimposing the photoactive layer at least partially with a coating composition A) comprising an electrically conductive polymer a) and an organic solvent b); III) at least partial removal of the organic solvent b) from the coating composition A) superimposed in process step II), thereby obtaining an electrically conductive layer superimposed on the photoactive layer. The present invention also relates to a layered body obtainable by this process, to dispersions, to an electronic device, to a process for the preparation of a photovoltaic device and to the photovoltaic device that is obtainable by this process.
