Semiconductor based PV cell is an optimized photovoltaic device that absorbs sun light and converts it to electricity. This well known photovoltaic effect that converts solar energy to electricity is the mechanism used by BIG SUN's major product, which is a crystalline silicon based solar cell. The structure of the PV cell is basically a large area of PN junction, where electrons and holes are created when solar energy is absorbed.

Power Generation by PV Cell : 01. Utilization of electron-hole pairs generated at silicon wafer when exposed to solar light
02. eparation of electrons and holes by internal electric field
03. Generation of electric power by the current and voltage created by the movement of electrons and holes

The benefits of Solar Energy are mainly in that the sunshine can be gathered almost everywhere on earth. Currently, the advanced Solar Energy System can also efficiently provide enough electricity power under the place where only has short duration of sunshine. Except the well know knowledge of non-polluting and non-damaging to the environment from Solar Energy,

High efficiency Solar Systems can also help to lower traditional electricity costs such as Fuel Energy. Additionally, Solar Energy can be the best solution to be used in rural areas or in suburb with limited access to power grids.
