Technology and R&D

The future of global sustainability hinges on clarity—where every tonne of carbon saved is measured, understood, and built upon. For corporations ready to lead, artificial intelligence (AI) isn’t a distant horizon; it’s the lens through which progress comes into focus.

A cancelled factory led to the sale. The solar cells produced by the equipment are “game-changing tech at liquidation values,” said the seller.

The researchers say the photo-assisted, self-chargeable aqueous Zn-ion energy storage device demonstrated a remarkable 170% increase in charge storage capacity at a constant current density of 0.02 mA/cm2 under consistent light exposure. Self-charging took 140 s to reach the potential of 0.9 V.

This is a proof-of-concept 1.22 kg laptop with a solar panel integrated into the lid, capable of absorbing enough sunlight in 20 minutes to power the device’s video for an hour.

To make it easier to adopt building integrated PV (BIPV) as a glazing material, a group within the IEA Photovoltaic Power Systems Programme (IEA-PVPS) has tackled the solar heat gain coefficient (SHGC) calculation for BIPV. It is part of IEA PVPS Task 15 international standardization efforts.

A research group in India has embedded a hybrid heterojunction solar cell as a bottom device in a four-terminal perovskite-silicon solar cell using a solution processing technique. The novel cell architecture, according to its creators, could be produced at significantly lower costs compared to conventional perovskite-silicon tandem designs.

IEA-PVPS has conceived a new test method and analysis of the impact of curvature in vehicle-integrated photovoltaics (VIPV) surfaces. Over the course of an 8-day summertime trial in south-eastern France, the researchers found that the curvature triggered irradiance and temperature non-uniformity of up to 261W/m² and 13 C, respectively.

Epsilon Group plans to invest INR 9,000 crore to set up a graphite anode manufacturing plant and INR 6,000 crore for a lithium iron phosphate (LFP) cathode manufacturing plant in Karnataka. In addition, it will invest INR 350 crore to build a battery materials and battery testing R&D and training center in the state.

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.
