With a recent spate of new solar cell records announced for PERC-based architectures pushing conversion efficiencies past 24%, it is a good time to reflect on the pioneering work at SolarWorld – the first to commercialise and ramp PERC to volume production. A special in-depth paper from former members of SolarWorld’s R&D and manufacturing team should be a compelling read and a leading reference paper in the future. Adding to the PERC-based theme is the paper from ISC Konstanz, providing further real world insight into achieving manufacturability of nPERT cells with conversion efficiencies approaching 23%.
