It's estimated that about two billion people in the world live without reliable electricity. Solar power has been discussed as one possible solution, but harnessing the sun's energy is costly, tricky and beyond the reach of most developing countries. A young Australian scientist hopes to change that. She's developed the iJET, a new type of solar cell that's cheap and easy to make, requiring not much more than a pizza oven, some nail polish remover, and a common inkjet printer. Her name is Nicole Kuepper. She is a 23-year-old Phd student at the University of New South Wales who has just won a couple of top Australian science awards.
