Tom Fontaine Greatcell Energy

First of all, how are you and your family doing in these COVID-19 times? 

Tom Fontaine: Not bad. I have 6 kids, and they’ve all done well. We are lucky in Perth. After a serious lockdown and hard borders, businesses have been open now for a while. 

Tell us about you, your career, how you joined Greatcell Energy.

Tom Fontaine: I’m an engineer with 30 years’ experience in starting and building companies. The company Greatcell Energy was listed on the Australian stock exchange, with a Market Cap of $67M, but it went bankrupt in Dec 2018. A group of us rescued the company, as it has a great 3rd generation solar technology that has the potential to disrupt the renewable energy industry. 

How does Greatcell Energy innovate? 

Tom Fontaine: We are world leaders in making solar cells from perovskite materials. It has the potential to provide solar power at a fraction of the cost of current solar technologies.  

How the coronavirus pandemic affects your business, and how are you coping?

Tom Fontaine: We had to stop production and operations for 6 months. Some of our operations are in Italy. We are now slowly getting back to the lab and setting up a production facility in New South Wales.  

Did you have to make difficult choices, and what are the lessons learned?

Tom Fontaine: Yes. Learned to work much more effectively remotely.  

How do you deal with stress and anxiety?

Tom Fontaine: Meditation. Going for walks.  

Who are your competitors? And how do you plan to stay in the game?

Tom Fontaine: Oxford PV. Saule Technologies. This technology area is such a new field that there are very few commercial products. 

We are working towards developing some of the first commercial perovskite-based products.
