ABSTRACT

Heterojunction photovoltaic cells exhibit two types of parasitic absorption, namely band edge absorption of ITO thin film and light absorption by doped amorphous silicon layer. These two types of parasitic absorption result in a decrease in EQE or IQE of heterojunction photovoltaic cells in the short wavelength region. Rare earth elements are widely used in optical functional materials due to their unique electronic configuration, which is attributed to the 4f electronic properties. The photoconversion phosphors composed of different rare earth elements are sorted with up/down conversion rare earth luminescent materials. The results of spectral allocation can make up for the shortcomings of the low absorption efficiency of the short wavelength of heterojunction photovoltaic cell. The preparation processes of rare earth phosphors generally include high-temperature solid-state method, precipitation method, sol-gel method, hydrothermal method, combustion method, etc. In this paper, the main preparation methods of rare earth phosphors are presented, and some typical cases are listed.
