The team was able to reach this level of efficiency through a unique combination of materials. Scientists achieve milestone ...

We show here that the argument presented by Rotenberg et al. in the preceding comment to account for the energy gap reported by us 1 in epitaxial graphene on 6H-SiC is unfounded. In our view ...

Developed by scientists in Germany, the triple-junction cell is based on a perovskite top cell with an energy bandgap of 1.84 eV, a perovskite middle cell with bandgap of 1.52 eV, and a silicon ...
