WebMay 27, 2024 · The downshifting process is a single photon process in which a high energy absorbed photon is converted into a low energy photon. This process is governed by the Stokes law. Luminescence of an optical material is ruled by the energy transfer process involved between acceptor and donor ions. WebAs an effective solution, the use of the luminescence down-shifting (LDS) technique is an important way to improve the short-wavelength response of a solar cell by shifting high-energy photons to the visible range. help desk tools troubleshooting
