Australian-designed technology will soon be responsible for 5% of all solar energy produced globally. And it's thanks to the PERC cell.
In the 1980s, a global race was underway: to find a more efficient way of converting energy from the sun into electricity.
Some 30 years ago, our research team at the University of New South Wales (UNSW) came up with a breakthrough, called the PERC silicon solar cell. The cells have become the most widely deployed electricity generation technology in terms of capacity added globally each year – comfortably exceeding wind, coal, gas, hydro and others.
PERC stands for Passivated Emitter and Rear Cell. By the end of this year, PERC technology will be mitigating about 1% of global greenhouse gas emissions by displacing coal burning. Assuming that its rapid growth continues, it should be reducing greenhouse gas emissions by 5% by the mid-2020s and possibly much more in later years.
The terrible bushfires in Australia this summer, enhanced by the hottest and driest year on record in 2019, underline the need for urgent reductions in greenhouse gas emissions. By far the most effective way is driving coal out of electricity systems through very rapid deployment of solar and wind.
Soon, our Aussie invention will be generating half the world’s solar power. It is a pertinent reminder of Australia’s capacity for finding transformative technical solutions to address climate change. But we need the right government support.
I am passionate about porridge. I eat it every day and it is the king of breakfasts.
It is also a malleable breakfast. It's convenient. If your office or home has a microwave you are only five minutes away from a delicious hot meal that will sustain you until lunch and beyond.
I am a porridge samurai. I've been cooking porridge in a microwave practically every working day for the past three years. During this time I have sharpened my sword. Today I would like to share with you my techniques.
