Review of Laser Doping and its Applications in Silicon Solar Cells
Abstract: Laser-doped selective emitter diffusion techniques have become mainstream in solar cell manufacture covering 60% of the market share in 2022 and are expected to continue to grow to above 90% within the next five years (ITRPV). This was a very rapid uptake of technology, coming from only ∼10% penetration in 2018, and has enabled over …

Emitter Diffusion
The emitter diffusion process is performed in a variety of ways. In this case a phosphorus containing coating is applied to the surface. The wafers are then put in a belt furnace to diffuse a small amount of phosphorus into the silicon surface.
