IBM Boosts Solar Cell Efficiency Using Magnifying Trick

IBM's researchers have been busily beavering away trying to improve solar power technology, and they've just come up with a neat solution that uses a surprisingly simple technique: concentrator photovoltaics. In much the same way as kids use magnifying glasses to focus the sun on things to burn them (we all did that,… » 5/16/08 10:15am 5/16/08 10:15am
