Abstract

The invention relates to a dye-sensitized solar cell photo anode and a preparation method thereof. The preparation method comprises the steps of attaching a pre-prepared precursor solution containing a titanium source to a conductive surface of transparent conductive glass, and performing evaporation so as to enable the transparent conductive glass to form a mesoporous structure titanium dioxide thin film layer; roasting the transparent conductive glass with the mesoporous structure titanium dioxide thin film layer at a low temperature to acquire a mesoporous structure titanium dioxide thin film layer with a metastable state; repeating the above two steps to acquire transparent conductive glass with multiple metastable-state mesoporous structure titanium dioxide thin film layers; and roasting the transparent conductive glass with multiple metastable-state mesoporous structure titanium dioxide thin film layers at a high temperature so as to acquire a mesoporous structure titanium dioxide thin film photon anode with a stable state.

Description

technical field [0001] The invention belongs to the field of dye-sensitized solar cells, in particular to a method for preparing a photoanode of a dye-sensitized solar cell, a photoanode of a dye-sensitized solar cell prepared by the method, and a dye-sensitized solar cell containing the photoanode Battery. Background technique [0002] Solar energy utilization supported by solar photovoltaic technology is bringing revolutionary changes to human energy consumption structure. Compared with traditional silicon-based solar cells, dye-sensitized solar cells (Dye-Sensitized Solar Cell, referred to as DSSC) has cheap cost, abundant resources, stable performance, simple production process, non-toxic, non-polluting and suitable for large Advantages of large-scale production. At the same time, dye-sensitized solar cells have a huge price advantage over other solar cells. It is estimated that the cost of DSSC is only 1 / 5 to 1 / 10 of that of silicon solar cells. DSSC will become a com...
