Photovoltaic energy has established itself as the most powerful source, even taking space away from the dreaded nuclear power. However, there is still a challenge ahead, and that is to make way for a new generation of solar panels that produce more electricity (i.e., have higher efficiency). A group of experts has succeeded in creating the first photovoltaic ceramics, with unprecedented potential and an unsolved problem: it defies the laws of physics with an incredibly small size.
