Should the industry be alarmed at the potential degradation susceptibility of tunnel oxide passivated contact (TOPCon) solar cells? Or are the problems easily addressed and more a reflection of rushed-to-market products? pv magazine contributor and consultant Götz Fischbeck reports.
Researchers from Germany’s Fraunhofer ISE developed new techniques to reduce silver consumption in tandem perovskite silicon solar cells and heterojunction silicon PV devices. The new processes relate to cell metallisation and module interconnection.
Australia’s solar market and pricing has been shaken up in recent months with the entrance of Tongwei Solar. Compounding this is the global free fall in panel pricing, which solar analyst Warwick Johnston says is yet to properly hit Australia. “There’s super cheap panels that are coming through and everyone will have to adjust their prices accordingly,” he says.
PV manufacturers, developers, and component suppliers have spent years negotiating a bewildering array of wafer and panel formats but recent developments in China hold the promise of long-awaited standardisation, as Vincent Shaw reports.
Indian scientists have produced high-purity polysilicon ingots from recycled solar cells using “spark plasma sintering” (SPS), and claim they may achieve a purity level comparable to commercially available products.
