RESEARCHNovember 17, 2008Inkjet printer advances solar hydrogenRun metal oxides through the process pharmaceutical companies use to make drugs and you could come up with a breakthrough for generating hydrogen from water using sunlight.The high-throughput screening process builds a library of data by inkjet printing combinations of metal oxides onto a sheet of glass, heating the samples, then measuring their electrical properties. The library promises to make it easier to design efficient photoelectrodes for solar water splitting, which has the potential to be a clean, inexpensive way to generate hydrogen for fuel. Materials scientists are increasingly turning to the technique of making many new substances at once and rapidly testing them to catalog their properties, which makes it easier to design materials for specific uses. The technique has been used for years to develop drugs.
