Efficiency boost in Si-based solar cells using tellurite glass cover layer doped with Eu3+ and silver nanoparticles

Designing a novel Eu2+-doped hafnium-silicate phosphor for an energy-down-shift layer of CsPbI3 solar cells

“…However, for the EDS layer, the characteristic emission of Eu 3+ could increase the efficiency of the solar spectral conversion for solar cells. 39–41 The PL spectra of various concentrations of Eu 2+ doped K 2 HfSiO 5 are shown in Fig. 4(c).…”

Sulfophosphate Glass Doped with Er3+ and TiO2 Nanoparticles: Thermo-Optical Characterization by Photothermal Spectroscopy

“…Embedding metal or semiconductor nanoparticles in different rare earth ion-doped glasses could be offered as an approach to overcome the limitations related to the narrow optical band of rare earth ions at high concentration [14,15]. Over decades, several research efforts have been dedicated for determining the effects of noble metal NPs (Ag and Au) and TiO 2 semiconductor on the emission of various rare earth ions [16][17][18][19][20][21][22][23]. All these studies suggested that the metal NPs and TiO 2 semiconductors enabled intense local fields in the proximity of the Ln 3+ s. The subsequent energy transfer between them inside varied glass hosts improved the photoluminescence properties.…”

Glass engineering to enhance Si solar cells: a case study of Pr$^{3+}$-Yb$^{3+}$ codoped tellurite-tungstate as spectral converter

“…On the other hand, Ag nanoparticles (NP) may enhance the local field of the rare-earth ion site and the energy absorbed by surface plasmon resonance of the electrons in the NP can be transfered to the rare-earth [13,14,15,16,17,18,19,20,21,22]. Lima et al [23] and Garcia et al [24] have studied tellurites as downconverters based in Eu 3+ doping and Ag nanoparticles codoping, where UV/Blue photons are converted to orange photons, which are better suitable to generate current in the silicon SC.…”
