French solar energy institute INES has developed new PV modules with thermoplastics and natural fibers sourced in Europe, such as flax and basalt. The scientists aim to reduce the environmental footprint and weight of solar panels, while improving recycling.

Scientists in Iraq have applied an amorphous carbon nitride (CNx) thin film as an anti-reflective layer in commercial crystalline silicon solar cells. They claim they were able to improve their efficiency from 5.52 to 13.05%.

Researchers in China have developed a four-junction tandem perovskite/CIGS cell. They claim it is the most efficient device of its kind with an n-i-p structure thus far. They used a novel surface passivation strategy to improve the perovskite cell efficiency and fill factor.

Researchers from Australia’s University of Wollongong presented a study for alkaline electrolysis where the liquid electrolyte is continuously drawn up a separator, leading to bubble-free operation at the electrodes. Meanwhile, Korean researchers developed a novel heterostructured catalyst, Argentina’s province of Tierra del Fuego presented its hydrogen strategy, Lhyfe and shipyard Chantiers de l’Atlantique are working on the world’s first offshore renewable hydrogen production demonstrator, and Saudi Aramco outlined its hydrogen targets in its first sustainability report.

Taiwanese analyst TrendForce said it expects global energy storage capacity to reach 362 GWh by 2025. China is set to overtake Europe and the United States is poised to become the world’s fastest-growing energy storage market.

UK scientists have developed a process using laser and x-ray pulses to observe what happens in the initial fractions of a second after light hits a solar cell. By applying the technique to various organic PV materials, they expect to gain insights that could quickly the improve the efficiency of such materials.

Scientists in China have developed a new recycling process for PV modules that can recover intact silicon cells from end-of-life products, and process them back into wafers. As part of the recycling process, the wafers are purified and surface-treated, making them suitable for integration into new, high-efficiency cells and modules.

The US National Renewable Energy Laboratory has made a tandem perovskite solar cell that can retain 80% of its original efficiency after 1,500 hours of continuous operation, or more than 62 days. To improve its stability, they used a hole-transporting material made of phenethylammonium iodide and guanidinium thiocyanate.

Azure Power has agreed to invest in a 1.25 GW mono PERC cell and module production facility that Premier Energies plans to open in India.
