Airbus taps Australian researchers to develop high-efficiency solar cells for space

Airbus Defense and Space has announced it will team with researchers from the University of New South Wales on a strategic research program to fast-track the development of high-efficiency solar cells to be used in space.

Airbus Defense and Space, a division of Airbus, has selected the University of New South Wales (UNSW) in Sydney to conduct a multi-year research project that is expected to push the performance of PV cells for space to the limit, both in terms of efficiency and radiation stability.

Airbus said the 3.5-year project will focus on the solar cells that are presently used to power spacecraft. Those cells are composed of several different layers of semiconductor materials that selectively absorb different parts of the solar spectrum. This selectivity enables the cells to operate more efficiently than the standard silicon solar cells used on domestic rooftops.

Professor Ned Ekins-Daukes, a researcher from the UNSW Sydney School of Photovoltaic and Renewable Energy Engineering, said the project will explore the merit of introducing patterned, non-planar layers into the cell structure, a technique known as interstitial light-trapping, which can further confine particular wavelengths of light into particular layers of the solar cell.

“Our research on high-efficiency solar cells can help extend the operational life of a spacecraft and lead to light-weight, lower-cost solar arrays,” he said.

Ekins-Daukes, who has previously developed nanostructured, strain-balanced PV absorbers that have utility for solar power conversion in the space environment, said the partnership with Airbus has the potential to open opportunities for commercialization of this technology in Australia and internationally.

“Partnering with Airbus’ experts will help us to understand the broader aerospace industry requirements for solar power and realise the full potential for these future solar power technologies,” he said.

Airbus Defense and Space UK Managing Director Richard Franklin said the project is a perfect example of industry and academia working together to develop and commercialize technologies to benefit and support the defence and space sectors in Australia.

“This is another example of the world-class research capabilities to be found in Australia, and in partnering with UNSW Sydney, we aim to bring these leading-edge research results to applications in space,” he said.
