Overview of the Solar Power Generation
The solar power generation is a type of power generation that converts the sunlight directly into electric energy using a solar battery without power generators.
The solar power generation system, or photovoltaic system, consists of a solar battery, storage battery, and power converter. When a solar battery is put together with a P-type semiconductor and a N-type semiconductor is exposed to sunlight, holes and electrons are generated in the solar battery through light energy. At this moment, the holes and the electrons are gathered toward the p-type semiconductor and toward the n-type semiconductor respectively to create an electric current through the potential difference.

Thanks to the advantages, the solar power generation has been emerging as an alternative to the thermal power generation or nuclear power generation, which display the risks of energy depletion, environmental pollution, and serious accidents. In Germany and other European countries, about 2% of the total power supply is covered by the solar power generation. It has such a bright future as the proportion is expected to reach more than 10% by 2050.
