UNSW professor Martin Green, who revolutionised photovoltaics, says sun’s power is ‘the best option out there’
The “father of PV” – University of New South Wales professor Martin Green – has become the first Australian to win the global energy prize from a shortlist that included Tesla’s Elon Musk.
UNSW said Green had been selected from 44 contenders from 14 countries by a committee of leading scientists to share the $820,000 prize with Russian scientist Sergey Alekseenko, an expert in thermal power engineering.
It said Green was honoured for revolutionising the efficiency and cost of solar photovoltaics, and making it the lowest-cost option for bulk electricity supply.
Green, the director of the Australian Centre for Advanced Photovoltaics, is a leading specialist in both monocrystalline and polycrystalline silicon solar cells.
In 1989, his team supplied the solar cells for the first photovoltaic system with an energy conversion efficiency of 20%. In 2014 he headed the development team that first demonstrated the conversion of sunlight into electricity with an efficiency of 40%.
Green also invented the PERC solar cell, which accounted for more than 24% of the world’s silicon cell manufacturing capacity at the end of 2017.
The research group he founded at UNSW – the largest university-based PV research group in the world – is broadly credited with driving the enormous reductions in costs in solar PV, largely through the work of Green’s students in establishing manufacturing centres in Asia.
“Not everyone would agree with that attribution,” said Green in an interview with RE on Friday, adding that Tesla’s Musk would have been his pick for the prize for his crucial work of putting electric vehicles on the agenda.
Green was keen to pay tribute to his UNSW solar stablemates, Zhengrong Shi, who left Australia to form Suntech Power in the US, and Stuart Wenham – the “Einstein” of the solar world, who died, aged 60, in December 2017.
