The structure of solar cellThe most popular structure, including the joint ligament of semiconductor p Semiconductor the cheapest and most on the world is silicon, was built by the silicon solar cell to smelting, and through the process of purification Until the crystals. And it was through a diffusion process seepage additives to create boundaries P. n. When the fill dopants phosphorus. A semiconductor type ligaments. (because of conductivity with an electron a negative charge) and when adding boron dopants are semiconductor type. (because of conductivity with hole, which has positive charge). So when the semiconductor type P and ligaments together, there will be a joint P n, structure of solar cell silicon. There may be a circle or square shape sheet thickness (mm) 200-400 micron 0.2-0.4 matte light is absorbed with electrical conductivity, diffusion layer The front electrode receiving light will look like a fishbone to obtain light area most. The rear electrode is full metal electrode surface.
