Vinay Rustagi, Chief Business Officer at Premier Energies Ltd, a solar cell and module manufacturer, believes that in just three to four years, the market will see solar cells with conversion efficiencies above 30 per cent, compared with about 25 per cent today. The efficiency here indicates how much of the sunlight falling on the solar cell is converted into electrical energy. But cost efficiency arising from improvements in cell efficiency (cells are assembled into modules) also played a significant role. I am pretty optimistic that by 2028 or 2029, there will be commercially available tandem solar cells with efficiencies above 30 per cent,” he told businessline. Kabra believes silicon–perovskite tandem cells will certainly enter the market before 2030.
