Capturing 'invisible' light from the sun to produce power

post-image

Most solar power devices are made from silicon, which cannot respond to light less energetic than the near infrared. So some parts of the light spectrum are going unused when it comes to solar power. But clever researchers at UNSW in Australia have worked out how to combine semiconductor quantum dots to absorb low energy light with molecular oxygen to transfer light to organic molecules - making it possible for normal silicon devices to operate.
