Researchers at Cambridge, Imperial and Singapore have developed a method to print ultrathin coatings on next-generation solar cells, allowing them to work in tandem with silicon solar cells to boost efficiencies.
A team of researchers from Cambridge’s Department of Materials Science and Metallurgy led by Professor Judith Driscoll and Dr Robert Hoye, working with Imperial College London and the Solar Energy Research Institute of Singapore, have developed a method to ‘print’ a protective coating of copper oxide over the perovskite device. They have shown that only a 3-nanometre thick coating is sufficient to prevent any damage to the perovskite after depositing the transparent top electrode.
