The paper presents the results of the investigation on flexible photovoltaic structures based on CdTe/CdS semiconductor compounds. The aim of conducted research was focused on adjusting of manufacturing technology used for rigid CdTe/CdS solar cells for flexible substrates requirements. The production technology of cadmium telluride based photovoltaic cells, used by authors previously for rigid cells, requires high temperatures which are not acceptable for standard flexible substrates. Thus, the technology process parameters must have been changed in order to match the temperature resistance of the substrate. Additionally, this technology change must include the conservation of obtained layers’ parameters. After a lot of experiments, such a compromise has been finally achieved.
