Zusammenfassung

Gettering of impurities is an important task in p-type mc-Si solar cell production. Phosphorus diffusion via POCl₃ is currently the most common way to achieve this. We report about the gettering efficacy of a co-diffusion in which POCl₃ is not used. Phosphorus and boron containing glasses are both deposited prior to the diffusion via atmospheric pressure chemical vapor deposition (APCVD). The presented APCVD glasses based co-diffusion allows a loading without spacing and therefore has the potential for a very high throughput. As we demonstrate in this work, the overall gettering efficacy in different kinds of stacks is similar to the gettering efficacy in non-stacked APCVD glasses based diffusions. The reduction of interstitial iron in the analyzed lifetime samples is ascribed to phosphorus diffusion gettering and works in stacks just as well.
