Swiss-based solar simulator equipment supplier Alfartec has had its new generation of module tester, BlueSky MT240 certified by China’s 3rd party lab, NIM at a ‘Silicon Module Super League’ (SMSL) member at a c-Si module manufacturing plant in China.

PV Tech reached its own little milestone of having reported and analysed the R&D spending habits of the same 12 key PV module manufacturers for 10 years. The results have just been published in sister technical journal Photovoltaics International as part of the annual leaders and laggards of R&D spending for 2016.

A key factor in the strong growth of the PV industry in 2017 is the Silicon Module Super League (or SMSL), comprised of the seven companies that will each ship in excess of 4GW of modules this year, well above all other module suppliers to the industry.

Nanoelectronics research centre imec has taken a perovskite/silicon tandem mini-module-on-cell stack to a record 23.9% conversion efficiency, significantly exceeding its 20.2% efficiency figures reported in 2016.

Specialist semiconductor and PV equipment supplier Intevac expects to start shipping its largest ever single tool order to a customer in China planning to ramp N-type mono IBC (Interdigitated Back Contact) solar cells and modules, including bifacial modules in the second half of 2017.

US-headquartered high-efficiency PV module producer SunPower reported a first quarter 2017 net GAAP loss of US$134.5 million, while guiding further losses of between $110 million to $135 million for the second quarter of the year as the company transitions its business model.

‘Silicon Module Super League’ (SMSL) member Trina Solar has reported a verified N-type monocrystalline Interdigitated Back Contact (IBC) solar cell with a conversion efficiency of 24.13%. Japan Electrical Safety & Environment Technology Laboratories (JET) verified the results.

The Solar Energy Research Institute of Singapore (SERIS) at the National University of Singapore (NUS) has developed the world’s first full-sized Interdigitated Back Contact (IBC) bifacial solar module using International Solar Energy Research Center (ISC) Konstanz, ‘ZEBRA’ solar cells.

China-based PV manufacturer Yingli Green Energy and industrial technology partners, Dutch research centre ECN and equipment manufacturer Tempress, a subsidiary of Amtech Systems have fabricated their first IBC (Interdigitated Back Contact) n-type solar cells on 6-inch monocrystalline wafers at the manufacturer's pilot line in China.

High-efficiency PV module producer and project developer SunPower has reached a production average cell conversion efficiency of 25% at its Fab 4 facility in the Philippines, the highest in the industry.
