A low viscosity, low boiling point, clean solvent system for the rapid crystallisation of highly specular perovskite films
Scientists at Oxford University have developed a solvent system with reduced toxicity that can be used in the manufacture of perovskite solar cells, clearing one of the barriers to the commercialisation of a technology that promises to revolutionise the solar industry. Perovskites – a family of materials with the crystal structure of calcium titanate – have been described as a ‘wonder material’ and shown to be almost as efficient as silicon in harnessing solar energy, and is significantly cheaper to produce.
By combining methylamine and acetonitrile, researchers have developed a clean solvent with a low boiling point and low viscosity that quickly crystallises perovski...
