| Abstract |
Background. At present, the problem of obtaining clean and renewable energy is more acute than ever. It is well known that modern energy sources, such as oil, gas and coal, are not endless. At the moment, the main solution to such problems is the production of
solar panels. One of the most promising types of solar cells are now solar cells of a new generation based on hybrid organic-inorganic perovskites. The purpose of the work is to develop and research methods for managing the quality of the technological process of synthesizing functional layers of solar cells (based on Ishikawa diagrams and Pareto diagrams).
Materials and methods. Methods of quality control, such as Pareto charts and Ishikawa, were used to solve the set tasks. Using these methods, transparent conductive coatings and metal oxide layers of solar cells based on perovskite were investigated.
Results. Cause-effect diagrams of Ishikawa and Pareto have been developed, which made it possible to identify the following main problems of obtaining functional layers of solar cells based on hybrid organo-inorganic perovskites: defects in the morphology of the film surface, deviations from a given thickness, unit failures. These three categories account for 80 % of all faults associated with the production of functional layers of such solar cells.
Conclusions. It is proved that the use of quality control methods allows to improve the quality parameters of coatings of solar cells. The main causes of defects were identified. These include the wrong choice of technological regimes and methods of obtaining,
as well as improper handling of equipment and materials. Actions aimed at eliminating these causes of defects are a priority.
