Solar cell technology is the fastest-growing power generation technology in the world. As a result of the fact, solar cells with a conversion efficiency of more than 40% are becoming available.
Photovoltaic cells are also known as solar cells. It is a semiconductor device that uses the photoelectric effect to convert sunlight into direct current. In fact, all solar cells are photodiodes made from semiconductor materials such as silicon. Solar cells work in three steps:
Photons in sunlight hit solar cells and are absorbed by semiconductor materials.
The negatively charged electrons fall off their atoms and begin to flow in the same direction to generate current.
Typical silicon solar cells can generate currents of up to 0.5 V and currents up to 6 A. Therefore, its maximum power is 3W.
Because the output of a single solar cell is so small that a large number of solar cells are interconnected to form a solar module, the combination of solar modules is called a panel, and the combination of panels is called a solar array. This is done to obtain the required power output from the photovoltaic system.
