Polycrystalline panels are comprised of many polycrystalline fragments melted together, resulting in their unique checkerboard look. Any area passivation layer has to be removed ahead of implementing the electrodes – for instance by laser ablation (see under). The cells must work properly beneath large irradiance situations, implying high electrical current https://byd47147.blogginaway.com/36426142/not-known-factual-statements-about-solar-cell
