Solar power usage is growing in the United States, Europe, and Australia, but what about developing areas that don’t even have access to basic electricity? Now that University of NSW PhD student Nicole Kuepper has developed a cheap and simple way of producing solar cells in a pizza oven, these areas might get a chance to use solar power too.
Photovoltaic cells are generally expensive to produce and require large manufacturing plants. But Kuepper’s technology needs relatively low-cost items such as ovens, ink-jet printers, and nail polish. Her iJET solar cells also use a low-temperature process.
The technology will most likely be ready for commercialization in 5 years. Kuepper speculates that the iJET could be used on-site in poor nations to provide otherwise scarce energy.
While I am interested to know exactly how efficient these low-cost solar cells are, they will be of limitless value to those who don’t have any electricity at all.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
