…the most production-viable being laser-induced melting of predeposited impurities (LIMPID), using either a residual phosphorous layer (typically the PSG layer) or an extra dopant film. Consequently, the equipment choice for c-Si cell production has never been more varied than on show at this year's EU…

…Laser-doping.· Within each also, there are different approaches. For example, laser-doping can be introduced via diffusion of phosphorous within the PSG layer prior to removal, or by the introduction of a phosphorous-containing layer after or during the SiNx deposition stage. Variants exist combining…
