“…[6] Noh et al demonstrated the improved device performance of 5.2% with various percentages of YBO 3 :Eu 3þ phosphor in TiO 2 photoanode. [7] Further, the blue light-emitting CaAl 2 O 4 : Eu 2þ , Nd 3þ nanophosphor played a vital role in downconverting UV light into visible light with the emission maximum at %440 nm, to enhance the device efficiency up to 6.61%. [8] To improve the light-harvesting ability with dc luminescence process and increase the photocurrent of a device, Wu et al introduced Y 2 O 3 :Eu 3þ as a p-type dopant in TiO 2 matrix and achieved the increased PCE of 6.52%.…”

Luminescent nanophosphors as spectral converters offer immense potential for dye‐sensitized photovoltaics (DSPV) to harvest a wide range of the solar spectrum. Herein, a novel structural design of DSPV using a downconversion (dc) nanophosphor layer in the TiO2 photoanode for both indoor (ambient) and outdoor applications is demonstrated. Cubic SrF2:Pr3+−Yb3+ nanoparticles are synthesized by a template‐free hydrothermal technique. The dc nanophosphor absorbs photons of the blue region, leading to emission of a broad luminescence band (green and red), which is well matched with N719‐dye absorption. The mixed‐valence state of Pr ions (Pr3+ and Pr4+) leads to trap‐assisted transition levels, which result in a broad visible emission. For the first time, a unique Pr3+−Yb3+ codoped dc system yielding tuned and intensified luminescence by effective crossrelaxation (CR) with a back energy transfer (BET) mechanism is designed and efficient working of the dc nanophosphor‐layered DSPVs under both outdoor 1 sun (AM 1.5 G) and indoor light (Warm‐3200 K; Day‐5000 K) conditions is demonstrated. Improved efficiency of 9.07% is attained in dc‐dye‐sensitized solar cells (DSSC) compared with a control‐DSSC (8.39%) at 1 sun intensity. Under indoor low‐light conditions (1000 lux), the dc‐DSPV achieves high power conversion efficiencies (PCEs) of 14.85 and 15.9%, respectively. This approach results in a 63.44% increment in output power density for dc‐DSPV compared with the control‐DSPV under LED 3200 K irradiation. These findings suggest that this configuration of dc‐layered DSPV can provide a new strategy for future indoor electronic operations under ambient light conditions.

“…2020, 20, 65 -88 converted from UV region due to the doping of Eu ions. [68] His study also revealed that the defect related emission has decreased with increased doping concentration of Eu ions relative to defect related emission observed for undoped TiO [103] By introducing 5 wt % of YBO 3 : Eu 3 + in the scattering layer, the energy conversion efficiency of a DSC was increased resulting with an increase in J sc (11.96 mA · cm À 2 ). Subsequently, M. Zahedifar et al, investigated the influence of Dy3 + doped GdVO 4 as DC material on the photovoltaic performance of DSC and achieved an enhancement in the efficiency by 7.39 % compared to the DSC lacking DC layer (6.70 %).…”

“…Y 2 O 3 /Y 2 O 2 S: Eu 3+ nanophosphors exhibited better luminescence resulting in the enhancement of DSC efficiency mainly attributed to the light scattering effect of Y 2 O 3 /Y 2 O 2 S: Eu 3+ nanocomposites . Y. Noh et al., dispersed uniformly 0∼5 wt % of Eu 3+ doped YBO 3 nano powders into TiO 2 scattering layer and reported an increment in the PCE of 5.20 % from 5.00 % in a DSC device without YBO 3 : Eu 3+ nanopowder . By introducing 5 wt % of YBO 3 : Eu 3+ in the scattering layer, the energy conversion efficiency of a DSC was increased resulting with an increase in J sc (11.96 mA ⋅ cm −2 ).…”

Although the efficiency of Dye‐sensitized and Perovskite solar cell is still below the performance level of market dominance silicon solar cells, in last few years they have grabbed significant attention because of their fabrication ease using low‐cost materials, and henceforth these cells are considered as a promising alternative to commercial photovoltaic devices. However, third generation solar cells have significant absorption in the visible region of solar spectrum, which confines their power conversion efficiency. Subsequently, the performance of current photovoltaics is significantly hampered by the transmission loss of sub‐band‐gap photons. To overcome these issues, rare earth doped luminescent materials is the favorable route followed to convert these transmitted sub‐band‐gap photons into above‐band‐gap light, where solar cells typically have significant light‐scattering effects. Moreover, the rare earth based down/up conversion material facilitates the improvement in sensitization, light‐scattering and device stability of these devices. This review provides insight into the application of various down/up conversion materials for Dye‐sensitized and perovskite solar cell applications. Additionally, the paper discusses the techniques to improve the photovoltaic performance in terms of current density and photo voltage in detail.
