New, inexpensive materials have been successfully used to create solar-powered fuel. The sun’s rays can drive reactions to create fuels such as hydrogen, but the cost of efficient materials has been far too high to compete with conventional petrol.
But Professor Kyoung-Shin Choi has used the same process employed to make gold-plated jewellery or surface-coat car bodies to create cheaper solar conductors.
The technology is not only much more affordable, but has also boosted the available surface area of the conductor.
