Presented at: 25th European Photovoltaic Solar Energy Conference and Exhibition - 5th World Conference on Photovoltaic Energy Conversion, Valencia, Spain, 6-10 september 2010.
Abstract:
We present the status of our process development of n-base silicon solar cells, and progress towards its industrial implementation. Independently confirmed efficiencies for Cz of 18.65% (239 cm2) have been obtained, and cells since then have already shown further improvement to more than 19%. To our knowledge these are the highest stable efficiencies obtained with industrial processing on 6 inch n-type wafers. We present an update of our process development, including efficiency improvements, transfer to 6 inch size, and key features of the current cells. Results are illustrated with data from Yingli PANDA pilot production.
