Perovskite Solar Cells reaches over 20% efficiency Updated On Fri, Jun 10th, 2016 by Saurenergy Researches at Ecole Polytechnique Fédérale de Lausanne (EPFL) are pushing the efficiency limits of perovskite solar cell by exploring the best way to grow these crystals. EPLF in a statement said researchers’ team headed by Michael Graetzel has found that, by briefly reducing the pressure while fabricating perovskite crystals, they were able to achieve the […] Read more
