Perovskite Solar Cells Exceed 20 Percent Efficiency
Ecole Polytechnique Fédérale de Lausanne researchers are currently working on pushing the limits of perovskite solar cell performance by exploring new ways to grow these unique crystals. Michael Graetzel and his team discovered that by reducing the pressure for brief periods of time while fabricating perovskite crystals, they are able to reach much better performances. These …
