Multicrystalline solar grade silicon solar cells from metallurgical process route and small Cz-Si test ingots have been investigated to further understand the impact of compensation and related reduced majority carrier mobilities. A possible PB complex which may prevent BO2i complex formation has been discussed recently by different research groups in several contributions. Our low temperature PL...
The focus of this work is the development of large area industrial type screen printed silicon solar cells made of 100% solar grade silicon (SoG-Si). The feedstock under investigation is produced by 6N Silicon Inc. from metallurgical grade silicon with a lower cost low energy refining technique compared to the Siemens process. Solar cells were processed at ISC Konstanz with industrial type process...
