Phosphorus requirements for solar cells

MIT Open Access Articles

solar cells is formed by phosphorus diffusion. A common P diffusion method is to expose Si wafers in a furnace at about 800–900 C to an atmosphere of POCl 3 and O 2 (with N 2 as a carrier gas), forming a phosphosilicate glass (PSG) on the wafer surfaces. This process step is usually called pre-deposition, and the resulting PSG provides a
