ARC Discovery Early Career Researcher Award (DECRA) recipient, Professor Baohua Jia, has led a group of researchers at the Swinburne University of Technology, The University of Sydney and The Australian National University in a collaboration to develop a solar absorbing, ultrathin film with unique properties that has great potential for use in solar thermal energy harvesting.

The 90 nanometre material is 1000 times finer than a human hair and is able to rapidly heat up to 160°C under natural sunlight in an open environment.The graphene-based material is expected to have applications in thermophotovoltaics (the conversion of heat to electricity), solar seawater desalination, and as a multitude of tunable light sources and photodetectors. The research collaboration has been funded through a Discovery Projects grant.
