IIT Bombay has marked a major milestone in India’s clean energy journey through a breakthrough by its start-up, Advanced Renewable Tandem-Photovoltaics India (ART-PV India). The team has successfully developed a four-terminal Silicon/CdTe-Perovskite tandem solar cell. It delivers a conversion efficiency of 29.8%—one of the highest ever recorded in India. The innovation is set to surpass the 30% efficiency barrier and significantly outperform current solar technologies.
Backed by the Government
Recognizing the strategic importance of this development, the Ministry of New and Renewable Energy (MNRE) has extended its full support. During a visit to the National Centre for Photovoltaic Research and Education (NCPRE) at IIT Bombay, minister Pralhad Joshi announced a grant of ₹83 crore to ART-PV India. The funding will enable the establishment of a pilot solar cell manufacturing facility within the IIT-B campus.
A Step Towards Aatmanirbhar Bharat
The minister highlighted the critical role of home-grown innovation in achieving India’s renewable energy goals. He urged IIT-Bombay and ART-PV India to accelerate the transition from lab-scale success to commercial deployment. He also emphasized the need for stronger integration with industry to support the nation’s self-reliance agenda under the Aatmanirbhar Bharat mission.
Towards Commercialization and Global Competitiveness
As reported by projectstoday.com, with the new pilot facility, ART-PV India is now set to bridge the gap between research and scalable production. Once commercially viable, the high-efficiency tandem solar cells could transform India’s solar manufacturing landscape. They could also enhance the country’s competitiveness in the global solar market.
