| Abstract | A two-step energy transfer was achieved in Er3+–Yb3+ co-doped transparent glass ceramics containing CaF2 nanocrystals, which involved down-conversion of an absorbed visible photon to two emitted near-infrared photons. Therefore, the Yb3+ emission centered at 980 nm was efficiently enhanced in response to the strongest absorption of crystalline silicon solar cells. The mechanisms of the two-step energy transfer mechanism were verified based on spectral and lifetime measurements, and the maximal energy transfer efficiency and corresponding quantum yield obtained were as high as 75.3% and 150.6%, respectively. As a result, near-infrared quantum cutting transparent glass ceramics will open a route to enhance the energy efficiency of silicon solar cells. |
