Solar polysilicon prices jumped by a further 4% this week, fuelling industry assessments that prices will soon jump above the RMB300/kg (US$44.74/kg) barrier.
Researchers at EPFL’s Photovoltaics and Thin Film Electronics Laboratory and CSEM’s Sustainable Energy Centre have claimed an efficiency of over 30% for perovskite-on-silicon-tandem solar cells, establishing “two world records”.
