Abstract: The main purpose of the work is to find an optimal way for the preparation of stable perovskite photovoltaic cell. Ten solar cells have been created with the active area consisting of CH3NH3PbI3 and CH3NH3PbI3-2Cl2 solutions. It was concluded that the CH3NH3PbI3-2Cl2 structure is more stable against environmental influences because of chlorine addition. Supplementary experiments were done to confirm the moisture influence. During the research has been found that films formed in humidity with 15 % RH have a different structure than perovskite manufactured in dry glove boxes filled with nitrogen atmosphere. We are concluding that perovskite grains have unified and their volume has increased. These processes have had a positive impact on the efficiency and stability of the cells.
Keywords: impact of moisture on perovskite; incorporation of chlorine atoms into perovskite structure; Perovskite photovoltaic cells; stability of perovskite solar cells
