Disorder-Engineered Inorganic Nanocrystals Set New Efficiency Record for Ultrathin Solar Cells

An international team of researchers from ICFO, University College London, and Imperial College London, report on a novel disorder-engineering technique for inorganic solar cells that achieves a record-breaking power conversion efficiency. Displayed over roof tops and in solar farms, silicon-based solar cells are, so far, one of the most efficient systems in generating electricity from sunlight, but their fabrication can be expensive and energy demanding, aside from being heavy and bulky. ...
