Features of Degradation of Silicon-Based Solar Photovoltaic Cells

Abstract

The article substantiates the need for the development of solar power plants in the energy system of various countries. Currently known solar cells have limited band gaps which makes their efficiency not very high. It has been observed that in long-term operation, degradation is the most important factor limiting the efficiency of photovoltaic cells, which is already low. Various factors caused by nature that reduce the efficiency of solar energy systems are mentioned. So, this work intends to present a method for efficient analysis of the photovoltaic cells degradation data. The necessity of developing methods for modeling the efficiency of a solar power plant for the photovoltaic cells degradation study has been proved. The calculation results for the rates of Si photovoltaic cells degradation are presented for different countries. It was noted that the main factor in the degradation process formation is manufacturing technology of photovoltaic cells.
