Dr Shuaifeng Hu, Post Doctoral Fellow at Oxford University Physics, examining the new thin-film perovskite material. Scientists at Oxford University Physics Department have developed a revolutionary approach which could generate increasing amounts of solar electricity without the need for silicon-based solar panels. Instead, their innovation works by coating a new power-generating material onto the surfaces of everyday objects like rucksacks, cars and mobile phones.
