EPFL researchers are pushing the limits of perovskite solar cell performance by exploring the best way to grow these crystals.
Professor Michael Graetzel and his team found that by momentarily reducing the pressure during part of perovskite crystal formation, they were able to attain the highest performance ever measured for larger size perovskite solar cells with over 20% efficiency, matching the performance of conventional thin film solar cells of similar sizes. Their results are published today in Science.
