dc.description.abstractUpgraded metallurgical-grade silicon (UMG-Si) offers benefits in costs and energy consumption, although the actual low silicon price enhances the need to reach the same level of solar cell efficiency and long-term behaviour as electronic-grade silicon. Especially boron and phosphorus are hardly removable from the UMG silicon feedstock. Therefore, also the purity of the feedstock is relevant. This work shows the progress on this route for two ingot suppliers. The usage of UMG material from different suppliers allows a direct comparison of material quality and solar cell performance. Additionally, a selection of solar cells from different height positions was cut up into small stripe-like cells with the intention of receiving an improved spatial resolution in electroluminescence, dLIT, bulk resistivity and IV measurements.eng
