“…Some materials exhibiting quantum-cutting with quantum efficiencies well above 100% were already reported, however only for a narrow range of excitation wavelengths, not absorbing significantly the ∼150 W/m 2 available. This kind of material would act mostly as a UV protective layer for specific applications [26].…”

“…Recent works have proposed P r 3+ -Y b 3+ co-doped materials to convert UV/Blue to near infrared photons [26,27,28,29,30]. By populating the 3 P n excited state of P r 3+ (∼ 20000 cm −1 ), the energy can be transferred to a neighbor Y b 3+ , ideally resulting in two Y b 3+ at the excited state 2 F 5/2 (∼ 10000 cm −1 ) [26,27,28]. This process can efficiently produce near infrared photons matching the peak of spectral sensitivity of the silicon cell [3].…”

Spectral converters are known to increase photovoltaic energy conversion by minimizing losses due to fundamental non-absorption and thermalization processes, and have been suggested to surpass the Shockley-Queisser efficiency limit in single junction solar cells. Here we present a detailed spectroscopic study of photoluminescence in tellurite-tungstate glasses doped and codoped with P r 3+ − Y b 3+ and Ag nanoparticles. The energy transfer mechanisms between P r 3+ and Y b 3+ are discussed based on the near infrared emission under excitation at 442 nm and on the upconversion emission under excitation at 980 nm. Fluorescence quenching of 2 F 5/2 level of Y b 3+ is observed by increasing the concentration of P r 3+ , as well as by the addition of Ag nanoparticles. In addition, a discussion on the potential of this glass to increase energy production in spectral converters is presented. The results suggest that the few undesirable energy transfer processes occurring in this material are difficult to be controlled or eliminated properly, resulting in intrinsic losses. This discussion is extended to the potential of glass science to enhance energy production in solar cells, showing that newer designs such as

Realizing an excellent spectral response by utilizing the ultraviolet parts of solar radiation is an important focus for enhancing the performance of photovoltaic cells (PCs). Pr 3þ and Eu 3þ ions co-doped multifunctional transparent GdPO 4 glassceramic is successfully prepared using a conventional melting quenching technique. In GdPO 4 : Pr 3þ -Eu 3þ , ultraviolet to visible downshifting is realized via the remarkable energy transfer from Pr 3þ to Eu 3þ ions by bridge Gd 3þ ions. Introducing the spectral conversion material by converting ultra-violet photons into visible photons is considered a very promising route; it can be applied to perovskite PCs by reducing the photo-degradation and enhancing the light harvesting, and it can be applied to hydrogenated amorphous-silicon carbide PCs by reducing the solar energy losses associated with spectral mismatch of the spectral response and energy. The development of downshifting Pr 3þ -Eu 3þ co-doped glass-ceramics might open up a new approach to achieving a better performance of photovoltaic devices.
