Coal India Ltd (CIL) will develop 2.5–3 GW of solar power capacity and 1.5–2 GW of wind power to supply renewable energy to AM Green’s upcoming green ammonia production facilities.

An international research team has developed a metallization technique for TOPCon solar cells that can reportedly reduce silver usage in the devices’ rear side by 85%. The scientists replaced the commonly used Ag fingers with intermittent Ag dashes for contact formation and Ag-free fingers and busbars for electrical conduction.

Experts set to speak at the NetZero Milan Expo-Summit 2025 on May 15 have told pv magazine that tunnel oxide passivated contact (TOPCon) will remain the dominant cell technology in the near term due to ongoing advancements, despite rising competition from back-contact and heterojunction technologies.

Bouygues Construction Australia and Equans Solar and Storage are trialling an autonomous piling system machine to build French renewable giant ENGIE’s 250 MW Goorambat East Solar Farm in northern Victoria.

Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a contactless method to measure the performance of back-contact solar cells, enabling in-line assessment of key parameters such as efficiency, fill factor, and current-voltage characteristics.

As hydrogen production scales, a pressing challenge emerges: how do we transport it efficiently and safely over long distances? This is where pipeline infrastructure, once the backbone of the oil and gas economy, must evolve to support the hydrogen economy of the future.

Fraunhofer Institute for Digital Media Technology IDMT has developed a solar module cleaning system that uses structure-borne sound and targeted mechanical vibrations to dislodge dust. Researchers will present the technology at Intersolar Europe in Munich from May 7 to 9.

Power-related incentives worth $38 billion account for 63% of the total state-level support potential for green hydrogen.

Scientists have developed a system that harvests rainwater running off PV panels for household use or hydrogen production. Their analysis showed that, in the southern Sahel, the system can meet both the energy and water requirements for electrolysis, with surplus rainwater covering up to 50% of a household’s daily water demand.

Researchers at the German research institute have demonstrated that the so-called EpiWafers could be used directly for solar cell fabrication without needing a pre-gettering step. Their experiments provide a proof of principle* for epitaxially grown silicon wafers from German wafer manufacturer NexWafe GmbH.
