Diagram of a solar cell showing labeled layers, including a front electrical contact grid, antireflection layer, absorber layer, back junction layer, and back electrical contact layer, with arrows indicating light entering and terminals connecting to a circuit. — solar cell A commonly used solar cell structure. In many such cells, the absorber layer and the back junction layer are both made of the same material.

When connecting solar cells in parallel, the primary purpose is to increase the total electric current produced by the assembly.12

While individual solar cells typically generate only a small amount of power, they are often combined in different configurations to meet specific electrical requirements. Connecting them in series is used to boost the voltage, whereas a parallel connection is specifically utilized to increase the current output of the solar panel.12
