Knowledge expansion
Photovoltaic, or photovoltaic power generation system, is a power generation system that uses the photovoltaic effect of semiconductor materials to convert solar radiation energy into electrical energy. The energy of photovoltaic power generation system comes from inexhaustible solar energy, which is a clean, safe and renewable energy. The photovoltaic power generation process does not pollute the environment and destroy the ecology.
Photovoltaic power generation system is divided into independent photovoltaic system and grid-connected photovoltaic system. Photovoltaic power generation system consists of solar cell array, storage battery, charge and discharge controller, inverter, AC distribution cabinet, sun tracking control system and other equipment.
history
Heinrich? Hertz first discovered the photoelectric effect in 1887, Albert? Einstein explained this phenomenon in 1905. Photovoltaic (PV) system uses the photoelectric effect of semiconductor materials to directly convert light into electric energy. The composition of semiconductor and the intensity and wavelength of effective solar radiation received by photovoltaic equipment will affect the power generation of photovoltaic equipment (Hz,1887; Einstein, 1905).
1954, three researchers from Bell Laboratories developed the first practical "solar cell". This battery can convert 6% of the incident solar energy into electric energy (Pedin, 2004). With the continuous progress of research and development, the conversion efficiency of photovoltaic devices has also improved.
