The research group led by Professor Martin Green has published Version 66 of the solar cell efficiency tables. There are 17 new results reported in the new version.

Japan’s Sekisui Solar Film and the Netherlands’ TNO have signed a letter of intent to explore collaborations related to flexible perovskite solar PV. Talks will be initiated on a potential perovskite module factory in Brabant and the exchange of relevant information.

A team of São Paulo-based researchers have found incorporating formamidinium cations into methylammonium-based lead iodide perovskite films increases the durability of perovskite solar cells when fabricated and measured under ambient conditions.

India’s AM Green and the Port of Rotterdam have signed an agreement to develop a supply-chain corridor for exporting green hydrogen, green ammonia and sustainable aviation fuels from India to Europe.

Lithium-ion batteries are everywhere, powering everything from consumer electronics to electric vehicles, residential PV storage systems, and, more recently, mitigating curtailment in large-scale wind and solar power plants. EVs are driving large-scale demand for Li-ion batteries which will result in substantial volumes of spent batteries in the near future. This scenario highlights the potential for repurposing EV batteries for second-life stationary applications, which could maximise their value before recycling. However, to fully realise this opportunity, several economic, technical, and regulatory challenges must be addressed and resolved.

Scientists have placed mist nozzles inside a bifacial PV module and measured it under an extremely hot climate. The module was found to generate up to 37% more electricity on sunny days and up to 46% more on cloudy days compared to standard monofacial panels.

While generation capacity from renewables has grown steadily, and commendable strides have been made to reduce the cost of solar PV cells for example, our ability to store, intelligently manage and distribute that energy still remains a massive challenge. This gap isn’t just a technical bottleneck, but also a strategic vulnerability that requires much attention across the entire renewable energy value chain.

Hitachi Energy India has reported a revenue of INR 1,921.9 crore in January–March 2025, a YoY growth of 13.1%. Profit after tax is 61.8% up YoY at INR 183.9 crore.

Building India’s hydrogen economy requires strategic infrastructure planning, targeted investments, and supportive policies. As industrial leaders continue demonstrating the viability of renewable energy transitions, the groundwork for hydrogen infrastructure follows naturally.

Larsen & Toubro has won Indian Oil Corp.’s tender for a green hydrogen production plant with a capacity of 10,000 tonnes per annum at a competitive bid of INR 397/kg.
