摘   要：

The narrow range of solar light absorption facilitated by the photoactive organicdyes has been restricting the significant development, and large-scale applicationsof dye-sensitized solar cells (DSSC). The major problem that limits thepower conversion efficiency (PCE) of DSSC is the limitations of the organic dyes(light absorbers in DSSC) to absorb beyond the visible region of solar spectrumthat resulting in lower PCE (≈13%) as compared with the commercializedtechnologies. Hence, the focus on developing efficient strategies to harvest theultraviolet and infrared light regions of the solar spectrum and effective conversioninto the absorption limit of dyes and thereby increasing the deviceperformance and stability is the emerging technological development in DSSCs.Rare earth ion-doped upconversion (UC) and downconversion (DC) phosphorsare the most promising solutions for the prevalent issues of the liquid junctionsolar cells. This review will focus on the emerging strategies for the PCEenhancement of DSSC with UC and DC materials. An exclusive review on thefacile approach of simultaneous usage of both the UC and DC phosphors and theeffective positioning of these spectral conversion phosphors, to achieve highlystable DSSCs with superior PCE is provided.
