Solar power generation is based on the photovoltaic (photovoltaic) effect, which is the phenomenon that light causes a potential difference between an uneven semiconductor or different parts of the semiconductor bound to the metal. This process, first of all, is the conversion of photons (light waves) into electrons, light energy into electrical energy process; The second is the process of forming voltage, with voltage, like building a high dam, if the two are connected, it will form a circuit of current.
