The work, carried out as part of the Energy Department's Sunshot initiative, has also led to development of a method to stabilise the crystalline structure of all-inorganic perovskite material at room temperature rather than only high temperatures, a key step in commercialisation of the concept.
"Most research into perovskites has centred on a hybrid organic-inorganic structure. Since research into perovskites for photovoltaics began, their efficiency of converting sunlight into electricity has climbed steadily and now shows greater than 22% power conversion efficiency.
"However,
