We present a high efficiency (η∼18.5%) mono-crystalline Si solar cells (A=15.6×15.6cm2) with a selective emitter structure using a conventional diffusion process (POCl 3 ) and screen printed contact. Especially, in this paper, we focus on the imp

In this work we evaluate the implied open circuit voltages (iVoc) at various stages of production of laser doped selective emitter (LDSE) solar cells using photoluminescence (PL) imaging The change of the iVoc values after the laser doping (LD) has s

Aside from having very good optical properties, the good ARC needs passivation effect (Si dangling bonds reduced) and thermal stability (during the firing of screen-printed metal contact). SiNx and SiO 2 are the most popular films as ARC and have bee
