Abstract: | The application of up-conversion nanomaterial particles (UCNPs)in enhancing photoelectric efficien-cy in solar cells can be mainly realized by promoting the luminescence efficiency of UCNPs.UCNPs could convert two or more low energy photons into a higher energy photon which is visible,this property is utilized to realize the light re-sponse range of solar cells increasing which would reach to the aim of promoting the photoelectric efficiency.It men-tioned the luminescence mechanism of up-conversion and the selection of host matrix materials.The synthesis of UC-NPs as thermal decomposition synthesis,hydrothermal methods and other synthetic methods are reviewed.The appli-cation of up-conversion nanomaterials in Si solar cells and dye-sensitized solar cells is emphasized.The trend to pro-mote up-conversion solar cells through the perspective of enhancing up-conversion luminescence is pointed out,mea-sures like heterogeneous ions doping,surface plasmon coupling and quantum dots sensitizing are highly recommended, and dye-conjugated,active-shell of lanthanides applied in core-shell structure may have huge potential for enhancing up-conversion luminescence in future research. |
