摘要

The impact of Fe, Cr, Ni, Ti and Cu is investigated in a model experiment. Impurities have been introduced to high purity feedstock to study their impact on the solar cell performance along the entire value chain. Characterisation on wafer and solar cell levels is presented. A physical model is presented and validated experimentally in order to define the impurity impact and arrive to SoG feedstock specifications.
