Abstract

The invention discloses a dye-sensitization solar battery with an up-conversion material signal enhancement layer, which is composed of a photo-anode substrate, a semiconductor porous thin film, dye, an electrolyte, a counter electrode and the up-conversion material signal enhancement layer; the signal enhancement layer made of the up-conversion material can absorb the infrared part of the sunlight and convert the same into visible lights for the excitation of the dye, thus greatly improving the utilization ratio of the solar energy to thereby efficiently improve the photoelectric conversion efficiency of the battery.

Description

(1) Technical field: [0001] The invention belongs to the field of solar energy and relates to a dye-sensitized solar cell. (two) background technology: [0002] With the increasing severity of the global energy crisis, people are eager to find a sustainable clean energy source. Solar energy, as an inexhaustible natural energy source, has increasingly attracted the attention of countries all over the world. Compared with traditional silicon solar cells, dye-sensitized solar cells have low cost and simple fabrication, and have attracted widespread attention all over the world. They are considered to be the most promising next-generation solar cells. However, the actual photoelectric conversion efficiency of dye-sensitized solar cells is only 11%, which is far from the requirements of industrialization. [0003] Although many groups at home and abroad have done a lot of work on improving the photoelectric conversion efficiency of dye-sensitized solar cells over the years, the...
