ABSTRACT: The understanding and therefore the optimization of n+-emitter formation in crystalline silicon using POCl3-diffusion requires a more detailed knowledge of the dopant source: the PhosphoSilicate Glass (PSG) layer. The growth of PSG during the phosphorus diffusion process depends on. .
(IBC) solar cells is presented. We use a stack of doping glasses deposited by atmo- (BSG) and phosphosilicate glass (PSG) on Czochralski-grown (Cz) silicon substrates. from the BSG layer into the underlying molten Cz-Si substrate. Simultaneously, the BSG-PSG stack is removed by laser ablation. In a. .
ABSTRACT: Phosphorus diffusion process for forming P-N junction is the heart of the silicon solar cell fabrication. One of the most important parameters that controls the diffusion profile of phosphorus into the silicon wafer is the temperature. This study focused on the influence of diffusion. .
Phosphorus silicate glass (PSG) etching represents the most challenging process step, since it has to be etched fast and residual free, without damaging the underlying emitter layer. In this paper we present a process sequence which meets all this requirements. With different CF-containing etch gas.
