Researchers at Stanford University and the US Department of Energy’s SLAC National Accelerator Laboratory have explored the potential recovery of lost capacity in lithium batteries by using an extremely fast discharging step to reconnect an island of inactive lithium with the anode. Adding this extra step slowed the degradation of their test battery and increased its lifespan by nearly 30%.

GAF Energy manufactures its Timberline solar tiles at a new facility in California. It claims that the Timberline Solar roof system is unique because it directly integrates solar technology into traditional roofing processes and materials.

Elsewhere, the ‘world’s first hydrogen racing truck’ has set out on this year’s Dakar Rally, with sponsorship from Saudi Aramco, and French hydrogen equipment business McPhy has been selected as preferred supplier for the GreenH2Atlantic project in Portugal.

An international research team has tested a holographic film based on prismatic concentrators that was presented by Russian scientists last year and is claimed to significantly reduce the operating temperature of solar modules, including that of thermal-photovoltaic devices. According to the new findings, the film is able to lower the operating temperature by around 3.5 degrees Celsius.

Growatt has been on an upward trajectory, recording an over 60% revenue increase in 2021, despite the many challenges posed in the solar industry. Lisa Zhang, global marketing director tells pv magazine how the Chinese PV inverter manufacturer overcame semiconductor chip shortages and rising costs amidst a global pandemic in addition to discussing key markets and new inverter products.
