As per the results, the new lattice-strained perovskite material achieved an open-circuit voltage of 1.30 volts, an impressive 93.5 percent of its theoretical maximum and one of the lowest energy ...

EPFL boosts efficiency. Researchers at EPFL, Lausanne, Switzerland, have found a way to significantly reduce energy loss and boost efficiency of perovskite solar cells by incorporating rubidium using ...

They used lasers to imitate a crystal lattice and ultra-cold atoms of rubidium-87 to imitate the electrons in the lattice. Then, they accelerated the rubidium atoms into a singularity in the energy ...

Physicists in Austria have created a new type of stable bound state made from two atoms that repel each other. This counterintuitive result – normally we think that two objects need to attract each ...

For instance, a plot of the band structure of silicon crystal, a common material used to make rooftop solar cells, shows a forbidden energy range—also known as a band gap—that is 1.1 electron ...

Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving ...
