In this work, we study the technique of Titanium Dioxide(TiO2) work electrode of the dye sensitized solar cells. The research contained four parts. (I)Fabrication of porous TiO2 with sol-gel method. (II)Compare the efficiency between dense layer non-dense layer. (III)Study the characteristics of nanometer photocatalyzer layer with silver atom on porous layer. (IV)Replace the commercial dye with the novel Discotic Liquid Crystal(DLC) material which we synthesized.
We compared different TiO2 particle size, and discovered the efficiency of 20nm particle which made Degussa reached 3.31%. After joining dense layer, the efficiency can be up to 3.75%. Finally, we sprayed a silver atom layer, the device efficiency increase to 4.13%. Because of the cost of the commercial dye, we replace the dye with DLC which were synthesized by ourselves. The efficiency is up to 0.46%. We offer a feasible direction in low cost and high-efficiency at present.
