Recent developments on low-cost industrial processing of n-type silicon solar cells
conference paper
We present the status of our process development of n-type silicon solar cells, and progress towards its industrial implementation. For cells with a so-called H-pattern front side metallization independently confirmed efficiencies for Cz wafers of 18.65% (239 cm2) have been obtained, and since then, cells 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 bifacial cells with H-pattern metallization. Results are illustrated with data from Yingli PANDA pilot production.
