Fast Solid‐State Chemistry: Reactions under the Influence of Microwaves

Solid‐state synthesis by microwave irradiation allows the “fascinatingly simple” preparation of crystalline CuInS2 from the elements. The product is not of “semiconductor quality” and can therefore not be used directly for solar cells. The method, however, which has been established for a long time in solvent and molecular chemistry, should rapidly find wider applications in solid‐state chemistry.
