Also known as photovoltaic Volter, referred to as photovoltaic (Photovoltaics (Photo- “light,” Voltaics “Volt), refers to a facility that uses photovoltaic semiconductor materials to transform solar energy into DC power energy. The core of photovoltaic facilities is solar panels. The semiconductor materials used for power generation are mainly: single crystal silicon, polysilicon, amorphous silicon, and cadmium cadmium. As countries have been actively promoting the application of renewable energy in recent years, the development of the photovoltaic industry is very rapid. [1]
As of 2010, solar photovoltaics have been put into use in hundreds of countries around the world. Although its power generation capacity still accounts for a small part of the total human power consumption, since 2004, the photovoltaic power generation connected to the power grid increased at an average annual rate of 60%. By 2009, the total power generation capacity has reached 21GW, which is the current fastest energy source. It is estimated that there is no photovoltaic system that has not been connected to the grid, and the capacity is about 3 to 4GW.
The photovoltaic system can be installed on the surface as a photovoltaic power station on the surface. It can also be placed on the roof or outer wall of the building to form a photovoltaic building integration.
Since the advent of solar batteries, the use of materials, technical progress, and maturity of the development of the manufacturing industry have driven the price of photovoltaic systems to become cheaper. Not only that, many countries have invested a large amount of R & D funding to promote the conversion efficiency of photovoltaics and provide financial subsidies for manufacturing companies. More importantly, policies such as the subsidy policy of the Internet -on electricity price and the standards of renewable energy proportions have greatly promoted the widespread application of photovoltaic photovoltaic in various countries.
