EPFL researchers are pushing the limits of perovskite solar cell performance by exploring the best way to grow these crystals. Michael Graetzel and his team found that, by briefly reducing the pressure while fabricating perovskite crystals, they were able to achieve the highest performance ever measured for larger-size perovskite solar cells, reaching over 20% efficiency and matching the performance of conventional thin-film solar cells of similar sizes.
This is promising news for perovskite technology that is already low cost and under industrial development.

However, high performance in pervoskites does not necessarily herald the doom of silicon-based solar technology...

Thin films of crystalline materials called perovskites provide a promising new way of making inexpensive and efficient solar cells. Now, an international team of researchers has shown a way of flipping a chemical switch that converts one type of perovskite into another — a type that has better thermal stability and is a better light absorber.
