Next-gen solar cells could be improved by atomic-scale redesign Updated On Fri, Sep 15th, 2017 by Saurenergy Solar cells harness energy from the Sun and provide an alternative to non-renewable energy sources like fossil fuels. However, they face challenges from costly manufacturing processes and poor efficiency — the amount of sunlight converted to useable energy. Light-absorbing materials called organic lead halide perovskites are used in a new type of solar cells that […] Read more
