With up to 80 million tons of solar photovoltaic panels expected to hit landfills globally by 2050, the national lab has taken a look into refining how crystalline silicon module recycling is done — in order to establish a circular market.
Also in the brief: IREC on energy storage interconnection, Wunder Capital and partners to invest more than $100 million in U.S. commercial solar, Photosol buying land rights near coal plants with eye toward transmission, and NREL on recycling solar panels.
Also in the brief: nearly 1 MW of solar has been installed on the roof of a 300,000-square-foot Kroger bakery facility, a big-rig driver installing solar on his truck, camouflage for solar panels and more.

A U.S. research group has developed a new solar cell, based on six active photoactive layers, to capture light from a specific part of the solar spectrum. The scientists claim that they could potentially reach a 50% efficiency rate with the new cell.

The US National Renewable Energy Laboratory examined five-year data to observe the most common system failure points and how to prevent them. Researchers considered residential, commercial and utility scale plants and found interesting results. While failures cannot be avoided completely, a key takeaway was that close monitoring and timely repair can effectively mitigate the financial effects of failures.
“Electricity providers will have to treat renewable energy customers as cost-conscious customers once these customers can look at data across the board.”
Getting the most out of a bifacial module requires a rethink at almost every level of system design and the industry is hungry for field data generated by such systems to better inform energy yield modeling and define the best approaches to maximizing yield at minimal cost. NREL’s three-year study into bifacial performance is beginning to yield results.
Although, the author of this article sees a path below 15¢ per watt. Researchers at MIT, working with financial modeling teams at NREL, have projected the electrical losses and financial gains of thinning solar cells from the current 160 micrometers to 50 micrometers.
