Boron emitter

WebThe two-step selective boron emitter is achieved by a combination of ion implantation and atmospheric pressure chemical vapor to fabricate n -type Cz front junction Si solar cells … WebIn the first step, the emitter (p–n junction) was formed by thermal solid phase diffusion of boron atoms at 900 C, for 30min, in N2 ambient. The doping precursor was coated and prebaked to form boron silicate glass (BSG) on the surface. After thermal solid-phase diffusion, laser irra-diation was applied to the diffused emitter surface at room
