large wafer

Looking to answer one of the year’s big questions concerning solar technology, energy consultancy DNV GL was invited by Trina Solar to compare the performance of its modules based on the 210mm wafer with the 166mm and 182mm dimensions also introduced recently. The analysis revealed an advantage for modules incorporating the largest wafer, based on simulation of bifacial systems at two locations in Spain and the United States.

Production is set to start in the first quarter of next year at the planned fab in Greiz, Thuringia. The facility will manufacture 370 W panels featuring half cells, large wafers and nine busbars.

The latest development on the module front sees manufacturers adopting larger wafer sizes in order to reach the industry’s raised expectations for power output. Older “M2” wafers have been the standard in recent years but now appear to be on the way out. Several theories about optimal size are gaining ground, but the future direction of the standard is still far from clear.

On the first day of this year’s EU PVSEC conference, veteran solar researcher Pierre J Verlinden won the Becquerel Prize for Outstanding Merits in Photovoltaics. The award recognized more than 40 years as a leading PV researcher in academia and at leading companies including Sunpower and Trina Solar. Its recipient spoke to pv magazine about what is needed from solar to stave off catastrophic climate change.
