Abstract

This invention relates to a preparation method for dye sensitization nm film solar cell electrode in which the solar cell includes the following three layers; the first is to deposit a layer of broadband gap semiconductor porous film with silk-screen printing or other film forming method on a glass substrate coated with transparent conductive film, the said semiconductor layer is for absorbing photosensitizer, the second is an electrolyte layer, the third is a transparent conductive glass coated with catalyst, coating metal powder and other high-molecular binder mixed slurry to the solidified to process 2 metal electrode silk-screen prinling, extrusion or insertion method on the first or third layer.

Description

technical field [0001] The invention relates to a solar battery electrode material and a preparation method thereof, and belongs to the fields of metal, organic and inorganic materials. technical background [0002] In 1991, the Lausanne Institute of Technology Laboratory in Switzerland reported a new dye-sensitized nano-thin film solar cell research results in Nature (O'Regan, B.; Graetzel.M, 1991, 353, 737), which was immediately recognized internationally. extensive attention and attention. [0003] Dye-sensitized nano-thin film solar cells are mainly composed of the following parts: photoanode, nanoporous semiconductor film, dye photosensitizer, electrolyte and counter electrode. Since the electrode of the dye-sensitized nano-thin film solar cell is an electrolyte with high oxidation-reduction ability, it is particularly corrosive to common metals. If no protection or treatment is used, the electrode will be corroded instantly. This is also the fundamental reason why t...
