Researchers at Hebrew University of Jerusalem have demonstrated 9.2% efficient printable semi-transparent, flexible halide perovskite solar cells with tunable color and transparency.

New documents reveal US government found only two cases of communications in Chinese inverters that differed from official documentation. The discrepancies were deemed “non-malicious” and “non-intentional” by investigators.

Sodium‑ion batteries are emerging as a safer, lower-cost alternative to lithium‑ion, with a recent international study highlighting their competitiveness in stationary energy storage. The research shows that ongoing investment and supply-chain development could enable broader adoption within the next decade.

A team of scientists has developed a novel hydrogel solar panel coating that is reportedly capable of lowering hot spot temperatures by up to 16.2 C, outperforming conventional hydrogels. The hydrogel also demonstrated superior durability and improved power output by up to 13%, according to the research group.

Shenzhen-based SolaEon has reported a 27.87% efficiency for a single-junction perovskite solar cell on a 0.076 cm² lab device, certified by China’s National Photovoltaic Industry Metrology and Testing Center.

Hongyuan Green Energy says it has produced a first batch of 40 µm monocrystalline silicon wafers that support full-size and half-cut formats, with slicing completed using the company’s in-house wafering equipment.

Pilot long-duration energy storage (LDES) project uses low viscosity, denser-than-water fluid. RheEnergise is panning for future projects in 10 MW to 100 MW range, with six to 20 hours of storage capacity.

Researchers in Hong Kong have developed a hybrid-energy heat pump that seamlessly combines absorption and compression cycles using crystallization-free ionic liquids, improving efficiency and reliability across varying solar conditions. Simulations in multiple Chinese cities show the system can significantly cut electricity use and cooling costs, making it promising for sustainable building cooling and future commercial scaling.

SunWiz market data ranks the manufacturer as the top energy storage supplier in Australia, Ireland, and South Africa.

Researchers have studied the potential of combining photovoltaic systems with compressed air energy storage (CAES) to power a commercial building in South Africa. They found that a co-optimized system could lower total capital costs by 15–20% compared to traditional sequential sizing approaches.
