Upgrades needed to process larger wafers, says VDMA

In an update to its International Technology Roadmap for Photovoltaics, German engineering association the VDMA notes standardization of wafer size is a topic of great interest to the country’s PV equipment manufacturers, and modifications to lines will be needed to process wafer pieces larger that 161mm.

UK scientists observe LID in action

A team of researchers from Manchester University claims to have identified the dominant process causing light-induced degradation in silicon solar cells. The process, termed “trap-assisted auger recombination”, arises from a defect in the bulk of the silicon material which lies dormant until exposed to sunlight.

Open letter: German government must protect its solar industry

In an open letter, more than 30 German PV companies and research institutes demand an industrial strategy to retain a domestic solar industry. According to the signatories, that means increased co-operation with France and the consideration of sustainability criteria for PV tenders

Rena and Aiko Solar Energy to collaborate on plating technology

Rena and Aiko Solar Energy will expand their collaboration into electroplating cell metalization technology. Germany’s Rena has already delivered some 4 GW of wet chemistry tooling to the Chinese PV producer, and will now deliver one of its InCellPlate to Aiko’s new Yiwu production facility, in the Zhenjiang province.

Natcore achieves 20.7% efficiency on silver-free back contact cell

The latest efficiency milestone for Natcore’s Foil Cell is verified by the NanoPower Research Lab at Rochester Institute for Technology. The result was achieved on the Natcore Foil Cell, which utilizes a lasering process and novel metallization strategy, eliminating the need for costly silver.
