Photovoltaic, also known as solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert sunlight radiant energy into electrical energy. The development of the photovoltaic industry is stemming from the growing demand for energy. The traditional fossil energy is faced with the problems of resource depletion and environmental pollution, prompting people to seek renewable and environmentally friendly alternative energy. Since the discovery of the photovoltaic effect of liquids by French scientist E.Becquerel in 1839, the development of solar energy in the world has a long history of more than 160 years. The United States is one of the earliest countries in the world to develop the photovoltaic industry, and the silicon photovoltaic cells invented by scientists in the 20th Gibel Laboratory laid the foundation for the development of the photovoltaic industry.
