The wafers are usually flippantly p-kind-doped. A floor diffusion of n-variety dopants is carried out about the front aspect in the wafer. This varieties a p–n junction a couple of hundred nanometers underneath the area. Monocrystalline solar cells and Polycrystalline solar cells differ during the composition on the silicon alone. https://aikido-history05825.blogdal.com/39001487/a-simple-key-for-solar-cell-unveiled
