EU-funded scientists have successfully developed a tandem solar cell capable of converting over 9 % of solar energy into hydrogen. This could prove a real breakthrough as it tackles one of the biggest energy challenges: grid-scale energy storage.
Solar energy is found abundantly in nature, yet a major obstacle to tap into the full potential of this energy source is that it is intermittent. For renewable energy to take hold on a larger scale, efficient and economical ways to store the Sun’s energy are needed.
