Efficiency enhancement in solar cells using photon down-conversion in Tb/Yb-doped tellurite glass
(2016-12-01)
Management of the solar spectrum incident on a solar cell was studied using tellurite glasses doped with Tb3+ and Yb3+ ions as a cover slip. From the transmittance measurements through the doped glass, a red-shift of the ...
Down-conversion process in Tb3+-Yb3+ co-doped Calibo glasses
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The down-conversion process in Tb3+-Yb3+ co-doped Calibo glasses was studied. The emission, excitation and time-resolved measurements indicated the existence of an energy conversion through the excitation of Tb3+ ions to ...
