Scientists in China built a four-terminal perovskite-CIGS tandem solar cell based on a top semi-transparent perovskite device with an efficiency of 21.26% and a high bifaciality factor of 92.2%. They used a solvent-annealing strategy to produce a perovskite film with full coverage, larger grains, superior crystallinity and free of detectable lead iodide impurity.

Avaada Group has collaborated with Switzerland-headquartered ammonia technology specialist Casale to develop a 1,500 tons per day (tpd) green ammonia plant in Gopalpur, Odisha.

Researchers at the University of New South Wales have used a 1 µm copper plating layer on the front silver grid of a TOPCon solar cell to create a protective barrier that reportedly reduces corrosion susceptibility. The cell showed significantly lower contaminant-induced degradation that unprotected reference devices.

Bharat Battery Show, part of the Bharat Mobility Global Expo 2025, saw participation of one hundred startups. Many of these startups are seeking funding from major conglomerates and investment firms.

Mellow Energy claims its ML-Flex panel is currently the world’s largest flexible perovskite solar module. Available in five versions with power output ranging from 260 W to 300 W, the module measures 1,200 mm x 1,600 mm and weighs only 2.04 kg.

Artificial intelligence (AI) and Data Analytics are transforming energy operations by introducing capabilities that were once unimaginable. These technologies provide actionable insights, automate processes, and enable real-time decision-making, making energy systems smarter and more resilient.

While China, South Korea, Europe, and the United States are also engaged in active development of all solid-state batteries, Japan is leading the charge, offering generous subsidies to technology proponents.

AM Green has partnered with DP World to jointly develop logistics and storage infrastructure to facilitate the global export of 1 million tonnes per annum (mtpa) of green ammonia and 1 mtpa of green methanol from its plants in India.

Techno-economic analysis conducted by NREL researchers has shown how perovskite-silicon tandem solar modules could currently hardly compete in cost with incumbent PV panels. Production costs for U.S.-made tandem products were found to range between $0.29/W and $0.42/W, with module efficiencies ranging from 25% to 30%.

Researchers from Belgium and the University of Cyprus have completed outdoor stability tests of perovskite solar mini-modules providing two-years of data on stability performance. The tests showed that the modules’ performance loss rates during the burn-in period of perovskites ranged between 7% and 8% per month.
