The University of Newcastle (UON) has printed solar cells in Lane Cove, Sydney, which can be mass-produced using conventional printers at low cost.
UON Professor Paul Dastoor created the organic solar material, which is as thin as a plastic chip packet, lightweight, and flexible.
Costed at less than $10 per square metre to produce, the goal is for the technology to assist Australia transition to solar power.
According to Dastoor, there is currently no other renewable energy technology available commercially that can be manufactured as quickly.
“The low cost and speed at which this technology can be deployed is exciting as we need to find solutions, and quickly”.
With over 99 per cent of the panels consisting of PET plastic, the panels may be more easily recycled compared to traditional silicon panels.
“We’re currently investigating recycling processes for this material. Our hope is that we can separate the outer PET layers and reuse them to make new panels with minimal processing,” said Professor Dastoor.
Dastoor said that his team was excited to take the printed solar cells to the streets as it has made significant progress to commercial readiness.
“Globally, there’s been so few of these installations, we know very little about how they perform in a public setting. This installation is the next critical step in accelerating the development and commercialisation of this technology. It presents a new scenario for us to test performance and durability against a range of new challenges” said Dastoor.
Professor Dastoor hopes that the public installation of the printed solar cells will generate conversion about energy as the Federal Government considered submissions to its technology investment roadmap.
“The government is seeking to bring down carbon emissions over the next 30 years and the community has been very engaged on this subject. Globally, there are many research groups like ours working on sustainable energy technologies and now, via the technology investment roadmap, is our opportunity to ensure we invest in and deliver clever solutions” said Dastoor.
He also hopes that the installation inspires young people to pursue STEM career pathways.
“As an educator and a father my greatest hope is that we may, through this public display, inspire young people interested in STEM to imagine the exciting new career possibilities that will exist for them, brought about through new industries like these,” said Dastoor.
“Young people inspired by this demonstration could become our first pivotal wave of high tech workers helping to bring printed solar to fruition - that’s an incredibly exciting idea”.
The next step for Dastoor and his team will be the establishment of an advanced manufacturing facility for printed solar in NSW that can handle industrial-scale production.
His long term goal is to coat as many surfaces as possible with the material, with many applications identified.
This includes for disaster relief and recovery applications; retractable recharging systems for electric vehicles, caravans/camping and the defence industry; floating covers for dams and pools; yacht sails; smart blinds for residential and high-rise buildings; and greenhouse covers.
