In the work were presented preparation and research techniques of the electrical properties of the perovskite solar cells, in which ZnS, ZnSe and ZnTe thin films were applied. Using these layers as the electron transport layer (ETL), a power conversion efficiency (PCE) of about 2.57% was obtained, and cells with hole transport layer (HTL) the PCE achieved a maximum 2.14%. By doping ETL and HTL with chalcogenides a maximum yield of 3.98% was obtained. Preparation of solar cells with two layers of ETL or HTL increased of PCE to 7.40% maximum. By doping bulk heterojunction of perovskite with the calcogenide thin layers has increased PCE of cells up to 13.84%., Popa, Mihail.
