Cambridge University researchers have discovered that adding potassium iodide solution to perovskite ink can boost the material's efficiency and stability. Perovskite solar cells are known to be cheap and highly-efficient, but sensitivity issues have prevented their commercial uptake. Lead Researcher Mojtaba Abdi-Jalebi, of the university's Cavendish Laboratory, said that tweaking the chemical composition of perovskites meant they could be used as "versatile solar cells or as coloured LEDs, which are essentially solar cells run in reverse". Outlining their research in journal Nature, the Cambridge scientists added that this process was easily scalable.
