Solar Cell design and selection of components
Solar cell is a kind of effect will use photovoltaic solar energy directly into electrical energy devices. The photovoltaic effect in solids, especially in the semiconductor, high energy conversion efficiency, it is also known as solar cells, semiconductor solar cells. A solar cell works Solar energy is converted into electrical energy to energy conversion, solar cells based on the working principle of semiconductor PN junction photovoltaic effect. In the pure silicon crystal, the number of...
