Abstract
• This review summarizes the application of rare earth material in solar cells. • The rare earth material application of perovskite solar cells is introduced. • The rare earth material improvement of solar cell is discussed. Organic-inorganic lead halide based perovskite solar cell has received broad interest due to their merits of low cost, a low temperature solution process, and high power conversion efficiency. Rare earth ion doped nanomaterials can be used in perovskite solar cell to expand the range of absorption spectra and improve the stability due to its up conversion and down conversion effect. This article reviews recently progress in using rare earth ion doped nanomaterials in mesoporous electrodes, perovskite active layers, and as an external function layer of perovskite solar cell. Finally, we discuss the challenges facing the effective use of rare earth ion doped nanomaterials in perovskite solar cell and present some prospects for future research.
