Scientists at the Indian Institute of Technology, Bombay, (IIT Bombay) have developed a new material that can convert sunlight into heat energy with unprecedented efficiency.

IIT Bombay Develops Nanostructured Material With Highest Solar Heat Absorption Research reveals that nanostructured hard-carbon florets can raise the temperature of the surrounding air from room temperature to 60 degrees Celsius.

IIT Bombay's Marigold-like nanostructured material demonstrates the highest solar heat absorption The material converts over 87% of light falling on it into usable heat energy

Researchers at IIT-Bombay have developed a groundbreaking nanomaterial designed to create eco-friendly solar heaters, offering troops stationed in northern regions a clean and efficient method to keep their tents and hutments warm.

Tiny carbon flowers turn light to heat at unrivalled efficiency, IIT team finds Carbon nanoflorets made by IIT Bombay researchers can convert incident sunlight to heat with 87% efficiency.

A Game-Changer in Sustainable Heating Solutions | IITBombay has unveiled an innovative solar-thermal technology, Surya Shakti, at the IInvenTive 2024

Newly designed Marigold-like nanostructured material shows record high efficiency of converting sunlight to usable heat — absorbing more than 97% of sunlight and converting it at over 87% solar-thermal efficiency.

IIT Bombay’s NCF Green Energy recognised as a ‘League of 10’ winner at the NASSCOM Emerge 50 Awards 2024, for its sustainable heating technology built on Nano Carbon Florets.

IIT scientists introduce new nano material for faster conversion of sunlight to heat. One metre square of NCF coatings converts 5 litres of water in an hour — five times greater than commercial solar stills.

Nanostructured porous hard-carbon florets demonstrated as an effective solar absorber with 87% photon thermalization efficiency, delivering bacteria-free hot water at 42 L m⁻² day⁻¹ with the lowest CO₂ footprint of any existing approach.
