Photovoltaic power generation is a technology of directly converting light energy into electric energy by using the photovoltaic effect of a semiconductor interface. The solar energy power generation system mainly comprises a solar panel (assembly), a controller and an inverter, and the main components are electronic components. The solar cells are connected in series and then are packaged and protected to form a large-area solar cell module, and then the photovoltaic power generation device is formed by matching with components such as a power controller and the like. The photoelectric effect is a phenomenon that a potential difference is generated between different parts of an uneven semiconductor or a semiconductor and a metal by light irradiation. Firstly, converting photons (light waves) into electrons, and converting light energy into electric energy; second, a voltage forming process.

A large number of production practices show that photovoltaic modules placed in the open air tend to accumulate contaminants such as dust on the light-passing surfaces after being used for a period of time. The accumulation of dust obviously reduces the luminous flux of the photovoltaic module, and further obviously reduces the electric energy output capacity of the photovoltaic module. Quantitative analytical tests showed that dust accumulation of 4g/m reduced the efficiency of photovoltaic module power output by 60%. What is more, the accumulation of large dust or pollutants, such as leaves, bird droppings, etc., can generate a hot plate effect, resulting in local high temperature of the photovoltaic module until the photovoltaic module is burnt out and scrapped.
