Norway-headquartered REC Silicon has revealed plans to halt operations at its Moses Lake facility in the U.S. in 17 days’ time. The company says it has taken the decision to maintain liquidity for its semiconductor business with American workers set to pay the price for President Trump’s trade war with China.

Belgian research institute imec has developed a new simulation framework it says can calculate the expected output of a bifacial PV system. The model could help improve developer understanding of the best system configurations for bifacial, and foster confidence among investors by providing a precise prediction of energy yields.

Chinese PV manufacturer Hanergy Thin Film Power Group today announced it has achieved 24.23% cell efficiency using its silicon heterojunction technology. The efficiency has been confirmed by Japan’s Electrical Safety & Environment Technology Laboratories.

Chinese solar giant JinkoSolar says it has put its products through a new set of standards testing for light-elevated temperature induced degradation, with the new examination regime set to be adopted as an industry standard.

Scientists at France’s Alternative Energies and Atomic Energy Commission, working with Swiss equipment supplier Meyer Burger, have hit 23.9% efficiency in large-scale production of heterojunction cells. The team also combined HJT cells with other technologies to produce a module with a 348 W power rating.

Having quickly proven their performance-boosting potential and durability, anti-reflective coatings are now found on the majority of modules rolling off the world’s production lines. Today, coating suppliers are looking to tackle losses from soiling as well as reflection, and working to keep up with cost reductions and extended lifetime expectations at module level. Older modules, installed without a coating, could also be set to benefit from the latest innovations.

Alcazar Energy has announced the start of commercial operation for a project at Benban, in Egypt. Alcazar says it is the first of more than 30 planned projects in the second round of the mammoth solar park to achieve grid connection, and one of four similar sized projects the company is working on at the site.

Global technology giant Google this week announced that it has signed an agreement to purchase the output from a 10 MW PV installation in Tainan City, Taiwan, to power its Changhua County data center on the island’s west coast. The agreement represents Google’s first move to procure renewable energy anywhere in Asia, and the first agreement made since a recent change to Taiwan’s Electricity Act allowed non-utility companies to buy renewable energy directly.

Scientists at the Okinawa Institute of Science and Technology have developed a process for the creation of perovskite cells with better than 20% efficiency. The cells use a tin-oxide electron transport layer, which the scientists say can triple their operational lifetime.

Quality assurance provider PI Berlin has found the solar industry has made significant improvements to module quality in the past six years and that, perhaps surprisingly, manufacturers in China and South East Asia are setting the standard by producing higher quality modules, on average, than other regions.
