Colloidal upconversion (UC) nanocrystals were explored as energy relay materials for dye-sensitized solar cells for the 1st time. The use of colloidal UC nanocrystals was found to significantly enhance the upconversion efficiency and improve the photocurrent of the cells for low IR irradn. intensity. UC nanocrystals of small size favor infiltration into a TiO2 film and bring higher relay efficiency. Finally, UC nanocrystals can serve as a scattering material to increase the light absorption capability of the cells and increase the overall photocurrent of the cells under simulated sunlight irradn.
