A new catalyst for lithium-air batteries

Scientists in the United States demonstrated a lithium-air battery with improved energy and stability performance, thanks to the use of molybdenum triphosphide as a catalyst for both charge and discharge reactions.

India ranked the world’s most attractive PV market by Ernst & Young

The latest edition of the accountant’s renewables attractiveness index has placed the nation in top spot for photovoltaics, helping it to fourth spot for overall clean energy investment. Mexico has been hammered by the government’s attitude to clean power and France has also slipped, four places.

New manufacturing process for 15.5% efficient perovskite solar panels

Stanford scientists have used a robotic device with two nozzles to quickly produce thin films of perovskite. With these films, they have manufactured perovskite cells and modules with efficiencies of 18% and 15.5%, respectively. According to them, this technique may enable the production of perovskite modules at a cost of around $0.25 per square foot.

pv magazine video: How quality can lower solar risk and insurance rates

This year’s pv magazine Quality Roundtable USA looked at extreme weather, and how resiliency can be built through modern O&M. Representatives from DuPont, Stäubli, Nextracker and RETC took to the virtual stage to discuss weather-related damages, and how to harness quality materials and workmanship to industry’s advantage, particularly when it comes to insurers. Ariel Re and NovaSource, meanwhile, looked at issues like risk management insurance solutions and asset stabilization. Case studies and presentations on the field performance of PV modules, and extreme hail and fire, were also included.

Massive corporate solar deal for the world’s largest telecommunications company

US giant AT&T has signed an agreement with Invenergy to purchase 500 MW from the upcoming 1.3 GW Samson Solar Energy Center in Texas. The deal will make AT&T one of the largest purchasers of corporate solar in the world.

Five pro-renewable energy actions to expect from President-Elect Joe Biden

As the U.S. economy continues to recover from its Covid-19-induced recession, it’s likely that Congress and the president will put together a multi-trillion dollar relief package, similar to the one that lifted the economy out of its doldrums following the 2008 economic crisis.
