Researchers in South Korea improved the performance of tin monosulfide (SnS) solar cells with a potassium fluoride-assisted post-treatment and a vapor transport deposition process. The treated solar cells had a power conversion efficiency of 4.10% and reduced recombination sites, compared to 3.42% for untreated devices.

The South Korean giant said its new EHS All-in-One provides air heating and cooling, floor heating, and hot water from a single outdoor unit. It can supply hot water up to 65 C in below-zero weather.

Envision Energy has launched a fully integrated energy storage solution combining hardware, software, and market-facing AI to optimize performance, safety, and trading. Its “Physical AI” platform embeds intelligence across cells, systems, and operations, enabling predictive maintenance and real-time market participation.

GIST researchers have developed a perovskite mini-module with 22.56% efficiency by improving the SnO₂ electron transport layer with PEI, reducing defects and electron loss. The module retained 94% of its performance after 500 hours, highlighting potential for scalable, stable perovskite solar cells and modules.

Swiss connector manufacturer Stäubli invested $10 million to expand its manufacturing facility in Bengaluru to increase production of PV connectors for domestic and global solar markets.

The Bangladesh Power Development Board (BPDB) has signed power purchase agreements with seven solar projects totaling 523 MW, marking a renewed push for utility-scale solar following the reinstatement of previously canceled approvals.

China installed a record 315 GW (AC) of new solar capacity in 2025, lifting cumulative installed PV capacity to 1.2 TW and pushing non-fossil power sources past thermal generation for the first time.

A report by energy think tank Ember finds India’s system operator regularly had to curtail solar generation as an emergency measure to maintain grid security, as other resources were already flexing to their maximum capabilities.

India’s Waaree Renewable Technologies has approved the acquisition of an approximately 55% stake in power transmission and distribution contractor Associated Power Structures Ltd for INR 12.25 billion ($133.6 million), subject to due diligence and closing conditions.

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.
