The most popular organic-hybrid solar cells are known to be perovskite solar cells with methyl ammonium lead iodide (MAPbI3) phase. This is due to the unique properties and high efficiency of perovskite solar cells. However, perovskite solar cells show a loss of efficiency shortly after their production. Production methods are cited as one of the reasons for this loss of efficiency. When perovskite production methods are examined, spin coating, thermal evaporation and thermal chemical vapor deposition (Thermal CVD) are seen as the most used methods. The drop casting method is seen as an effective method in the production of crystals locally. In this study, MAPbI3 films were produced by using chemical vapor deposition and drop casting methods together. The morphological and structural properties of the films obtained were determined by using SEM and XRD methods. The produced perovskite films were exposed to water vapor. Aging processes in materials due to water vapor have been characterized by electrical conductivity methods.
