Perovskite solar cells have new potential

Researchers in Saudi Arabia have used computational modelling to determine the best materials for perovskite solar cells, an advance that could add commercial viability to the promising power source.
Perovskite solar cells can be cheaper and easier to produce compared to silicon solar cells, but they lack long-term stability, and this has hindered their progress. The most-studied perovskites for solar applications comprise a negatively charged lead-halide inorganic skeleton, partnered with posit
