Background. It is known that the usual sources of energy will soon be exhausted, as they are being restored at a very low rate, and the demand for them is increasing every year. In this regard, the urgent task is to create easily reproducible, environmentally friendly and energy-efficient substitutes. The aim of the work is to describe the method of obtaining functional layers of solar cells based on hybrid organo-inorganic perovskites, and also to diagnose the structural elements.
Materials and methods. The implementation of the tasks was achieved through the use of simple and accessible methods, such as the sol-gel method and the roller method. With the help of a scanning electron microscope Vega3 Tescanand a laser microcontrolograph-profilometerMitaka, photographs of the investigated films were obtained.
Results. Both types of coatings are of good quality and can be used as a functional word for solar cells based on hybrid organo-inorganic perovskites.
Conclusions. The analysis of the obtained results has shown the high efficiency of the methods described in the work, therefore, this technique is suitable for the creation of energy-efficient solar cells.
