Abstract

The up-conversion fluorescent powder is prepared by adopting a liquid-phase co-precipitation method and a thermal reaction method, and the up-conversion fluorescent material film is deposited by using a suspension coating film method or metal organic chemical vapor deposition. By adjusting the doping amount of Yb, Er, Tm and other rare-earth elements, the up-conversion fluorescent material can absorb near-infrared light with the wavelength between 800 and 2,000nm and emit visible light, and also can absorb ultraviolet light with the wavelength between 200 and 350nm and emit the visible light. The up-conversion fluorescent material film is applied to silicon-based thin-film solar cells, and the spectral absorption range of the silicon-based thin-film solar cells is widened. The silicon-based thin-film solar cells have the maximum photoelectric conversion efficiency in the visible light range, so the photoelectric conversion efficiency and the stability of the silicon-based thin-film solar cells can be improved by applying the up-conversion fluorescent material.

Description

technical field [0001] The invention relates to a high-efficiency solar cell using an up-conversion fluorescent material film and a preparation process for the high-conversion efficiency up-conversion fluorescent material film. Background technique [0002] Thin-film solar cells are a new technology developed in recent decades. It focuses on reducing energy consumption and process costs in the production process. Experts call it a green photovoltaic industry. Compared with monocrystalline silicon and polycrystalline silicon solar cells, the amount of thin-film high-purity silicon is 1% of it. At the same time, low-temperature plasma-enhanced chemical vapor deposition technology, electroplating technology, sol-gel coating technology, and printing technology are widely studied And applied to the production of thin film solar cells. Since low-cost glass or stainless steel flakes and polymer substrates are used as substrate materials, production costs are greatly reduced and la...
