Photovoltaic: short for solar power generation system, it is a new type of power generation system that directly converts solar radiation energy into electric energy by using photovoltaic effect of semiconductor materials of solar cells. There are two modes of independent operation and grid-connected operation.
At the same time, solar photovoltaic power generation system is classified as centralized, such as large-scale northwest ground photovoltaic power generation system; One is distributed (bounded by >: 6MW), such as photovoltaic power generation system on the roof of industrial and commercial enterprises and photovoltaic power generation system on the roof of residential buildings.
Solar Photovoltaic effect, short for photovoltaic (PV), also known as photoelectric effect, refers to the phenomenon that uneven semiconductors or parts combined with semiconductors and metals generate potential difference under illumination.
Photovoltaic is defined as the direct conversion of radiant energy. In practical application, it usually refers to the conversion of solar energy into electric energy, that is, solar photovoltaic. Its realization is mainly through the use of solar panels made of semiconductor materials such as silicon, using light to generate direct current, such as solar cells that can be seen everywhere in our daily life.
