UPCONVERSION

Untapping solar energy resources

Nature Photonics volume 14, pages 528–530 (2020)Cite this article

Subjects

The photovoltaics market has long been dominated by silicon, but further improvements of these solar cells require novel approaches. Now, triplet–triplet annihilation photon upconversion has been used to harvest photons from below the bandgap of silicon, extending the spectral response and potentially improving the efficiency of these cells.
