FYI,

Not necessarily new tech., but innovative uses of existing technology
will lower the cost of building solar power satellites.

: For her 10th birthday, Nicole Kuepper received an inspirational
: present from her parents - her first solar-energy kit.

: It sparked a fascination with solar technology that last night led
: to Ms Kuepper, 23, winning two Australian Museum Eureka Prizes for
: her scientific research.

: She has developed a simple, cheap way of producing solar cells in a
: pizza oven that could eventually bring power and light to the
: 2 billion people in the world who lack electricity.

: Ms Kuepper is a PhD student and lecturer in the school of
: photovoltaic and renewable energy engineering at the University of
: NSW.

: "I love working with passionate people who want to help address
: climate change and poverty by thinking and experimenting outside
: the square," she said.

: Today's photovoltaic cells that convert sunlight to electricity are
: expensive and need sophisticated, "clean" manufacturing plants.

: Ms Kuepper realised a new approach would be needed if affordable
: cells were to be made on site in poorer countries: "What started
: off as a brainstorming session has resulted in the iJET cell
: concept that uses low-cost and low-temperature processes, such as
: ink-jet printing and pizza ovens, to manufacture solar cells."

: While it could take five years to commercialise the patented
: technology, providing renewable energy to homes in some of the
: least developed countries would enable people to "read at night,
: keep informed about the world through radio and television and
: refrigerate life-saving vaccines".

: Ms Kuepper said that the solar cells should be of high enough
: quality to be used anywhere in the world, including Australia.

: An advocate of green technology, she gives talks about solar energy
: to the public, has held miniature solar car races to teach
: indigenous children about renewable energy, and was a delegate at
: the 2020 Youth Summit in Canberra in April.

: Ms Kuepper was awarded the British Council Eureka Prize for Young
: Leaders in Environmental Issues and Climate Change and a $10,000
: study tour to Britain.

: She also won the People's Choice Award, in which almost 16,000
: members of the public voted for their favourite scientist out of
: six finalists. Twenty Eureka Prizes worth $200,000 were awarded
: last night at a ceremony at Royal Randwick Racecourse.
