A College of Sydney Professor creating innovative photo voltaic expertise has acquired $2.78 million in analysis funding from the Australian Renewable Vitality Company (ARENA) to business the concept in a partnership with Sydney startup SunDrive.
Professor Ho-Baillie, the John Hooke Chair of Nanoscience on the college’s the College of Physics and Sydney Nano Hub, is becoming a member of forces with Sydney-based SunDrive to commercialise superior photo voltaic tech utilizing perovskite-silicon cells.
The analysis mission led by Prof. Ho-Baillie, in collaboration with SunDrive, will enhance the business viability of perovskite-silicon tandem photo voltaic cells.
Whereas silicon is the semiconductor materials used presently, perovskites – crystal buildings constructed from mineral compounds – have emerged as a promising various, with the efficiencies of perovskite photo voltaic cells already approaching the silicon model
This mission will give attention to stacking perovskite on high of silicon to kind a tandem photo voltaic cell, fairly than utilizing silicon by itself.
Ho-Baillie stated thought of this stacking is to transform extra vitality from the solar to electrical energy.
“The effectivity that may be achieved by a perovskite-silicon tandem in a laboratory is now over 30%, whereas the very best effectivity for a silicon cell by itself is just under 27% within the laboratory and round 23% commercially,” she stated.
“There isn’t a lot room for silicon to enhance as a result of its theoretical restrict is barely 30% – however for perovskite-silicon tandem, it’s 40%.”
The cell design is the “future” of photo voltaic expertise, Ho-Baillie stated, nevertheless extra work on the idea is required.
“To make them the principle business possibility, we need to enhance the sturdiness of those cells – particularly underneath the mix of thermal and light-weight stress,” she stated.
“We additionally must develop industry-relevant manufacturing processes which are cost-effective.
“Lastly, we have to develop applied sciences of encapsulating and packaging the tandem cells to bigger photo voltaic panels. These panels, not simply the cells themselves, additionally should be sturdy and extremely environment friendly.”
Different investigators on the mission embrace Professor David McKenzie, Dr Jianghui Zheng and Dr Arafat Mahmud, from College of Sydney, and SunDrive cofounders Vince Allen and David Hu and Prof. Alison Lennon.
Professor Ho-Baillie additionally leads the College of Sydney’s node of the Australian Centre for Superior Photovoltaics, which just lately had its operations prolonged with $45 million in funding from ARENA for photo voltaic PV analysis to 2030.
SunDrive, based in 2015, raised $21 million in a Collection B in October final yr. The corporate was cofounded by uni mates Vince Allen and David Hu after Allen developed the concept of utilizing copper as a less expensive various to silver in rooftop photo voltaic panels whereas finding out for a PhD.
The brand new cells may very well be as much as 30% cheaper than present panels. The photo voltaic PV {industry} already makes use of round 10% of the world’s silver, and 20% of complete industrial demand. Copper is almost 100 occasions cheaper than silver and much more ample.
SunDrive’s backers embrace the CSIRO’s VC fund Important Sequence Ventures, the federal authorities’s Clear Vitality Finance Company, Atlassian founder Mike Cannon-Brookes, Blackbird, Canva founder Cameron Adams, former PM Malcolm Turnbull and Tesla chair Robyn Denholm.
The corporate has been profitable in progressing from lab-scale proof-of-concept to business, full-size photo voltaic panel fabrication and is likely one of the solely two corporations on the planet which has demonstrated full-area commercial-size cells with a licensed effectivity above 26%.
Allen, SunDrive’s CEO, stated they have been trying ahead to working with Professor Ho-Baillie and her staff.
“It’s thrilling that ARENA is supporting this mission with the objective of accelerating the event of extra progressive photo voltaic applied sciences akin to perovskite silicon tandems,” he stated .
ARENA CEO Darren Miller stated the funding goes to main universities and researchers in photo voltaic PV.
“Australia’s photo voltaic researchers have helped to make photo voltaic PV the most cost effective type of vitality in historical past, however to create a future by which Australian photo voltaic vitality provides the world with clear energy, fuels and merchandise, we have to be formidable and drive the price of photo voltaic even decrease,” he stated.
