When someone of the stature of Martin Green says the cost of solar PV technology will halve again by the next decade, you sit up and take notice. Even more so when he says solar will be the world’s most popular energy source by 2050.
For the University of New South Wales’ Prof. Martin Green is considered one of the world’s leading PV researchers. His department’s technological breakthroughs in silicon cell efficiency have not only given us the solar panels we know today but also put Australian PV research at the centre of world PV technology.
“The costs of solar will halve again by 2025 is my prediction,” he told a conference in Sydney on Wednesday. “We are at 60 cents per watt manufacturing now but we will get down to 30 cents per watt some time before 2025.”
