Human hair can boost perovskite solar cell performance, new study finds



If you had your hair cut at a barber’s somewhere in the vicinity of a Queensland University of Technology campus sometime last year, there’s an outside chance you could have contributed to the advancement of cutting edge Australian solar technology.

Researchers from QUT have used human hair snippets gathered from a Brisbane barber to create carbon dots – zero-dimensional carbon-based materials the size of a few tens of nanometers – which are in turn being used to improve the performance of perovskite solar cells.

Perovskite solar cells have shown great promise in the eternal global quest to deliver even lower-cost and higher efficiency solar PV electricity, but still face a number of key hurdles to commercial viability,…
