Mercedes to bolster PV system at manufacturing facility with SolidFlow battery

The goal is to have a green energy source that runs around the clock.

Triple-junction solar cells have technical potential to reach 44.3% efficiency

A research team has investigated the optical properties of perovskite/perovskite/silicon triple-junction cells and has found these devices may have a practical efficiency potential of 44.3% assuming idealized electrical parameters. These cells may also potentially achieve a fill factor of 90.1%.

How safe are LFP batteries?

Researchers found that nickel manganese cobalt (NMC) batteries generate larger specific off-gas volumes, while lithium iron phosphate (LFP) batteries are a greater flammability hazard and show greater toxicity, depending on relative state of charge.

Power Electronics plans 20 GW inverter factory in U.S.

Spanish inverter manufacturer Power Electronics has an annual inverter production capacity of 30 GW, but it now plans to build a new 20 GW manufacturing facility in the United States.

U.S. steel solar module frames have one tenth embodied carbon of Chinese aluminum alternatives

An independent study commissioned by Origami Solar and conducted by Boundless Impact Research & Analytics found that U.S.-made recycled steel module frames show a 90.4% reduction in greenhouse gas emissions compared to traditional virgin material aluminum module frames shipped from China.

Charged by the IRA, U.S. expected to outpace Europe in lithium-ion battery cells

Global manufacturing of lithium-ion battery cells is expected to triple between 2022 and 2025, according to a report from Clean Energy Associates.

First Solar unit achieves world record CIGS solar efficiency of 23.64%

The new solar cell achieved a maximum power conversion efficiency of 23.75% and a certified efficiency of 23.64%, thus beating the previous world record of 23.35% achieved in 2019 by Japan’s Solar Frontier. The result was confirmed by the Fraunhofer ISE.

The impact of climate-based PV panel degradation rates on inverters

New research from Belgium shows the importance of assessing inverter reliability by including climate-based PV panel degradation rates. The scientists found that, especially in hot and arid climates, PV inverters should be designed with parameters above the standard value.

Fraunhofer ISE, Oxford PV produce 25%-efficient perovskite-silicon tandem PV module

Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) announced today that it had produced at 421 W perovskite-silicon tandem glass-glass module measures 1.68 m2.

Meyer Burger to cease PV module production in Germany

Meyer Burger, a Switzerland-based heterojunction cell and panel manufacturer, says it will stop making PV modules in Germany, but it will continue to produce solar cells in the country to support its panel production operations in the United States.
