India, July 16 -- The Indian Institute of Technology (IIT) Bombay has developed a solar cell that could play a vital role in India's clean energy future. The innovation comes from the Advanced Renewable Tandem-Photovoltaics India (ART-PV India), a start-up incubated at IIT Bombay (IIT-B).

Called the 4-terminal Silicon/CdTe-Perovskite tandem solar cell (one on top of the other), the technology has achieved a remarkable 29.8% conversion efficiency of sunlight to energy, one of the highest ever recorded in India. It is seen as a breakthrough that could push solar cell efficiency beyond 30%, significantly outperforming current technologies.
