Researchers in China have fabricated a perovskite-silicon tandem solar cell that utilizes an indium oxide sputtering buffer layer to protect the perovskite absorber and the electron transport layer from potential damages arising from the electrode deposition process. The new layer not only ensured this protection but also showed strong optical and electrical properties.

ICRA, an Indian credit rating agency, says India could add 22 GW of solar capacity in fiscal 2025 and 27.5 GW in fiscal 2026, pushing the nation’s total installed PV capacity to 131.5 GW by March 2026, up from 82 GW as of March 31, 2024.

Sunways’ new three-phase inverters have efficiency ratings of up to 98.6% and European efficiency ratings of 98.2%. They are available in five versions, with power outputs ranging from 15 kW to 30 kW.

Scientists in Malysia have tested a system that combines a PV panel and thermoelectric generators (TEGs) and have found it offers potential for “moderate” nighttime power generation. It is suitable for small household applications such as LED lights, laptops, phone chargers, and wireless routers.

JA Solar says it has launched a hydrogen business with the establishment of JA Hydrogen, a new unit based in Beijing with CNY 100 million ($13.8 million) of registered capital.

China has reduced the export tax rebate for solar products, lowering refunded taxes for Chinese PV exporters and eating into their profit margins. The move might force some companies to increase export prices to mitigate potential financial losses.

Thornova Solar has started producing solar modules in Indonesia. The company says the move is in line with changing US market regulations. It plans to supply customers with modules from Indonesia or the United States by mid-2025.

Lithuania has decided to tighten its cybersecurity laws, banning manufacturers from countries deemed national security threats, including China, from remotely accessing management systems of solar, wind, and storage facilities. The European Solar Manufacturing Council has backed the move.

The Chinese manufacturer said the device is based on dense passivating contacts that reduce parasitic light absorption and improve passivation. It used a streamlined manufacturing technique that is reportedly about one-third more effective than TOPCon mainstream technology.

Taiwan-based electronics manufacturer Para Light Electronic has launched a compact solar LED streetlight with integrated PV panels and battery to provide up to 15 hours of area-lighting for pedestrian walkways and roads.
