BESSt announced that its new redox flow battery technology delivers 20 times the energy density of conventional vanadium flow storage systems. The battery is based on a zinc–polyiodide redox flow chemistry developed by the Pacific Northwest National Laboratory.

A Chinese-US research group claims to have achieved a power conversion efficiency of over 50% in an n-type single-junction solar cell by inhibiting light conversion to heat at extremely low temperatures. The result was achieved at temperatures of 30-50 Kelvin, which are a few tens of degrees above absolute zero.

The price of silver rose above $44 per ounce this week after gaining more than 30% in six months, with silver expert Philip Newman telling pv magazine it could exceed $50 per ounce next year, raising pressure on PV module makers to curb silver use.

Nuclear plants generated a record amount of power in 2024, surpassing record set in 2006, but industry optimism is not backed by economic data or investment, says the World Nuclear Industry Status Report 2025.

A research team from the U.S. National Renewable Energy Laboratory has analyzed n-type modules deployed in a 3 MW commercial PV project in an effort to assess the high degradation rate reported by the plant owner. The scientists found that ultraviolet-induced degradation (UVID) was a major factor affecting the facility’s performance.

Jetson said its new heat pump system has a coefficient of performance of up to 4.1 and an energy efficiency rating of up to 11.7. The new product integrates air quality sensors, an energy monitor, and a “smart” thermostat.

The U.S. Federal Highway Administration (FHA) has warned that cellular radios have been found in unspecified foreign-made inverters and batteries used in PV highway infrastructure, according to Reuters. pv magazine speaks with cybersecurity expert Uri Sadot about the risks.

Sandia National Labs researchers have created a new dataset on the rates and types of rooftop PV connector failures. Their analysis has shown that tight wire bending radius, extra dirty connectors, and loose nuts are the most common failure causes in 6,276 connectors deployed between 2014 and 2017 across seven U.S. regions.

Scientists from Japan, Saudi Arabia and the United States have investigated existing back-contact perovskite solar cell architectures and have proposed a strategy to help reach commercial production.

The National Renewable Energy Laboratory and Sandia National Labs have created a new nomenclature for PV connectors to reduce confusion amongst installers and developers, while improving deployment practices. They catalogued a sampling of twenty-five commercially available 4 mm connectors.
