Silicon-perovskite tandem cells with a whooping 32.5 per cent efficiency

29, 30, 32... -- these are not random numbers, but the efficiency of solar cells, measured by the percentage of incidental sunlight they convert into electrical power. The ellipsis at the end of the line is also not a coincidence, as the efficiency of tandem solar cells has already exceeded 32%.
