This work deals with the development of stable perovskite solar cell structure. In the research, two sets of perovskite photovoltaic cells were manufactured with a different way of their production. In the first series, an active perovskite layer CH3NH3PbI3-xClx was applied in a glovebox with N2 atmosphere. In the second series was used glove box filled with air with controlled 15% relative humidity. Perovskite solar cells were analyzed for the most frequent degradation mecha-nism, which is moisture. XRD measurements revealed decomposition of the ac-tive perovskite structure with lead iodide increase. XRD measurements, along with EDS analysis, have also confirmed that chlorine is not in the perovskite structure and applies only during the manufacturing process. According to the output parameters of the cells, along with the changes in the perovskite structure, it was found that solar cells manufactured in the controlled humidity environment are more stable. However, they do not achieve such conversion efficiency as cells produced in an inert atmosphere.
