Optical-electrical direct conversion method This method uses the photoelectric effect to directly convert solar radiation energy into electrical energy. The basic device of optical-electrical conversion is solar cells. A solar cell is a device that directly converts sunlight energy into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, solar panel the photodiode will turn the sun’s light energy into electrical energy to produce Current. When many batteries are connected in series or in parallel, solar panel it can become a solar cell array with relatively large output power.
Solar cells are a promising new type of power source, solar panel with three major advantages of permanence, cleanliness and flexibility. Solar cells have a long life, as long as the sun exists, solar cells can be invested in one time and used for a long time; and thermal power generation, nuclear power generation In contrast, solar cells do not cause environmental pollution; solar cells can be large, medium and small, solar panel as large as a million kilowatt medium-sized power station, as small as a solar battery pack for one household, solar panel which is unmatched by other power sources.
