These solar cells are flexible, cheap to produce and could even be sprayed on to buildings – and now engineers at UNSW are smashing new world records. The new cells were made out of perovskite, named after Russian mineralogist Lev PerovskI which can be produced at lower temperatures and are 200 times thinner than traditional silicon cells.
Dr Anita Ho-Baillie, a Senior Research Fellow at the Australian Centre for Advanced Photovoltaics (ACAP) and her team at UNSW said the versatility of the material means it’s even possible spray or paint on solar cells
“Imagine being able to cover every surface of buildings, devices and cars with solar cells,” Dr Ho-Baillie said.
The UNSW team has managed to achieve the highest efficiency rating with the largest peroskovite solar cells to date.
“Perovskites came out of nowhere in 2009, with an efficiency rating of 3.8 per cent, and have since grown in leaps and bounds,” she said.
“These results place UNSW among the best groups in the world producing state-of-the-art high performance perovskite solar cells,” she said.
The new goal for the team is to lift perovskite solar cell efficiency to 26% and make it more durable.
The Australian Centre for Advanced Photovoltaics is a national research collaboration based at UNSW. Research partners in the project include the University of Queensland, Monash University, the Australian National University, the University of Melbourne and the CSIRO Manufacturing Flagship.
