Multi-Junction Solar Cells: What You Need To Know
Solar cells are made of semiconductor material, typically silicon in crystalline solar cells. Traditionally, a solar cell has two layers: an n-type with a high concentration of electrons and a p-type with a relatively low concentration of electrons. When sunlight hits the n-type layer, electrons flow from that section to the second and create an electrical current that …
