Printed solar panel gets real-world test

Elizabeth Gracie
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.

In 2016 I published a blog article titled Moonshots for Australia: 7 For Now. It’s one of many I have posted on business and innovation in Australia. In that book, I highlighted a number of Industries of the Future among a number of proposed Moonshots. I self-published a book, Innovation in Australia – Creating prosperity for future generations, in 2019, with a follow-up COVID edition in 2020. There is no doubt COVID is causing massive disruption. Prior to COVID, there was little conversation about National Sovereignty or supply chains. Even now, these topics are fading, and we remain preoccupied with productivity and jobs! My motivation for this writing has been the absence of a coherent narrative for Australia’s business future. Over the past six years, little has changed. The Australian ‘psyche’ regarding our political and business systems is programmed to avoid taking a long-term perspective. The short-term nature of Government (3 to 4-year terms), the short-term horizon of the business system (driven by shareholder value), the media culture (infotainment and ‘gotcha’ games), the general Australian population’s cynical perspective and a preoccupation with a lifestyle all create a malaise of strategic thinking and conversation. Ultimately, it leads to a leadership vacuum at all levels. In recent years we have seen the leadership of some of our significant institutions failing to live up to the most basic standards, with Royal Commissions, Inquiries and investigations consuming excessive time and resources. · Catholic Church and other religious bodies · Trade Unions · Banks (and businesses generally, take casinos, for example) · the Australian Defence Force · the Australian cricket teams · our elected representatives and the staff of Parliament House As they say, “A fish rots from the head!” At best, the leadership behaviour in those institutions could be described as unethical and, at worst….just bankrupt! In the last decade, politicians have led us through a game of “leadership by musical chairs” – although, for now, it has stabilised. However, there is still an absence of a coherent narrative about business and wealth creation. It is a challenge. One attempt to provide such a narrative has been the Intergenerational Reports produced by our federal Government every few years since 2002. The shortcomings of the latest Intergenerational Report Each Intergenerational Report examines the long-term sustainability of current government policies and how demographic, technological, and other structural trends may affect the economy and the budget over the next 40 years. The fifth and most recent Intergenerational Report released in 2021 (preceded by Reports in 2002, 2007, 2010 and 2015) provides a narrative about Australia’s future – in essence, it is an extension of the status quo. The Report also highlights three key insights: 1. First, our population is growing slower and ageing faster than expected. 2. The Australian economy will continue to grow, but slower than previously thought. 3. While Australia’s debt is sustainable and low by international standards, the ageing of our population will pressure revenue and expenditure. However, its release came and went with a whimper. The recent Summit on (what was it, Jobs and Skills and productivity?) also seems to have made the difference of a ‘snowflake’ in hell in terms of identifying our long-term challenges and growth industries. Let’s look back to see how we got here and what we can learn. Australia over the last 40 years During Australia’s last period of significant economic reform (the late 1980s and early 1990s), there was a positive attempt at building an inclusive national narrative between Government and business. Multiple documents were published, including: · Australia Reconstructed (1987) – ACTU · Enterprise Bargaining a Better Way of Working (1989) – Business Council of Australia · Innovation in Australia (1991) – Boston Consulting Group · Australia 2010: Creating the Future Australia (1993) – Business Council of Australia · and others. There were workshops, consultations with industry leaders, and conferences across industries to pursue a national microeconomic reform agenda. Remember these concepts? · global competitiveness · benchmarking · best practice · award restructuring and enterprising bargaining · training, management education and multiskilling. This agenda was at the heart of the business conversation. During that time, the Government encouraged high levels of engagement with stakeholders. As a result, I worked with a small group of training professionals to contribute to the debate. Our contribution included events and publications over several years, including What Dawkins, Kelty and Howard All Agree On – Human Resources Strategies for Our Nation (published by the Australian Institute of Training and Development). Unfortunately, these long-term strategic discussions are nowhere near as prevalent among Government and industry today. The 1980s and 1990s were a time of radical change in Australia. It included: · floating the $A · deregulation · award restructuring · lowering/abolishing tariffs · Corporatisation and Commercialisation Ross Garnaut posits that the reforms enabled Australia to lead the developed world in productivity growth – given that it had spent most of the 20th century at the bottom of the developed country league table. However, in his work, The Great Reset, Garnaut says that over the next 20 years, our growth was attributable to the China mining boom, and from there, we settled into “The DOG days” – Australia moved to the back of a slow-moving pack! One unintended consequence of opening our economy to the world is the emasculation of the Australian manufacturing base. The manic pursuit of increased efficiency, lower costs, and shareholder value meant much of the labour-intensive work was outsourced. Manufacturing is now less than 6% of our GDP , less than half of what it was 30 years ago!
