Researchers discovered new method for improving perovskite solar cell performance
(WorldNews Finland)

With humidity assisted thermal treatment the overall efficiency increases almost 45 per cent. The Aalto-developed treatment builds on previous breakthroughs improving the efficiency and longevity of perovskite solar cells using established printing methods (carbon back contact based perovskite solar cells or CPSCs). These findings make it possible to further enhance the efficiency of these types of solar cells. Perovskite solar cells are solar cells where the light harvesting layer consists of lead halide with perovskite crystal structure. Globally, perovskite cells are studied intensively since they might prove to be an alternative to silicon cells that require a lot of...
