Abstract
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.
Gianluca Coletti is senior scientist at ECN solar energy where leads research projects in the area of solar cell technology and Si material and coordinates the PV silicon material area. He has more than 10 years experience in PV with 45 publications in various scientific journals (like Advance Functional Materials, JAP, APL and Progr. in PV) and conferences. Invited speakers at several international PV conferences, he is considered leading expert in the area of silicon materials for PV.
