As always we have a selection of technical papers from some of the industry’s leading minds. Radovan Kopecek and Joris Libal from ISC Konstanz tackle one of the biggest issues impeding the rollout of bifacial cell and modules, how to standardise their measurement. As long as there is no commercially available means to measure their gain, bifacial modules will struggle to improve their market penetration. The materials section includes an excellent paper from Fraunhofer THM examining the optimization of diamond wire sawing. The method is becoming increasingly predominant with some equipment manufacturers shelving their slurrybased tools. Here Fraunhofer assesses how to squeeze even more efficiency out of diamond wire saws. CSEM meanwhile explores the required metallization and interconnection process changes required to enable a production-scale shift to silicon heterojunction PV. Mark Osborne provides his latest capacity expansion report as upgrades to higher efficiency lines continue to drive planned investments.
