Investigation of Busbar Effect on Performance of Solar Cells

The transformation of solar radiation into electricity in the solar cells of the photovoltaic panel is the most commonly used and renewable energy production method. A photovoltaic system is the heart of solar module. Many solar cells are combined with solder to form a photovoltaic module. Electricity generation in the module is produced by solar cells consisting of multi-layered semiconducting material. When the sun’s rays reach their cells, the electromotive force between these layers occurs and the electric current flows. The higher the intensity of solar radiation, the higher the electric current flow. In this study, the effect of the number of busbar in the solar cell on the electricity production performance of different solar radiation values was modeled using MATLAB program and the effect was investigated in detail with experimental results. With this study, it is aimed to clarify the effect of the busbar of solar cells on electricity generation and to direct the researchers working in this area. In addition, in solar energy applications, it will be possible to increase the electricity production performance by passing to very coherent solar cells, as well as to reduce the negativity that occurs in the solar cells over time. Both simulation and experimental results are compared; it is showed that the voltage values are nearly close but the current values are approximately different. This difference is related to the resistance characteristics
