Biography
Dr Matthew Stocks has more than 25 years research and development experience in renewable energy and photovoltaics.
Since returning to ANU in 2013, I have been CI on several ARENA funded research projects, all examining aspects of renewable energy generation. These span from high efficiency solar cell concepts, including silicon based IBC solar cells and tandem solar cells comprising perovskites or GaAs with silicon as the lower bandgap device and through to studies supporting high penetration renewables including 100% renewable energy and sustainable transport.
Our work (https://re100.eng..anu.edu.au) on pumped hydro energy storage and integration of renewable energy in Australia has had wide engagement from industry, government and the general public, culminating with the award of the Eureka Prize for Environmental Science in 2018.
From 2000-2012, I gained extensive experience in research and development, and commercialisation of silicon photovoltaics. I drove the development of the cell manufacturing process at ANU from idea through to proof of concept. In 2003, I then joined Origin Energy for the design and build of the pilot facility, ultimately taking the role of Chief Technologist, overseeing the full suite of SLIVER technology R&D. I continued in this role when the joint venture Transform Solar, between Micron and Origin, was formed and manufacturing moved to the US. SLIVER commercialisation was a major endeavour with over $250M in expenditure, with more than $7M in royalties flowing to ANU. My development activities spanned the full breadth of SLIVER development, from silicon material refinement through to new product development and certification testing.
