Abstract: |
A dye sensitize solar battery based on the light scattering membrane electrode of the titanium dioxide Nano Rods is provided, which belongs to technical field of solar battery manufacturing. The invention comprises light anode, electrolyte solution and counter electrode, which is characterized in that the said light anode includes in turn the first layer closely connected with the conducting fundus and the second layer contacted with the first layer. The first layer is a dense TiO2 thin membrane formed by the TiO2 particles of 2 to 5 nm in grain diameter, while the second layer is a Nano Rods thin membrane formed by the TiO2 tiny particles of 5 to 60 nm in grain diameter and Nano Rods with diameter of 6 to 11 nm and length of 90 to 450. The mirror face diascoptic lighting intensity is obviously weakened while the diffuse transmission light intensity is increased in the infrared band and near infrared band of 600 to 900. The first layer is 50 to 15 nm in thickness while the second layer is 2 to 12 micron in thickness. The dye sensitize solar battery is characterized in high light scattering property, simple preparation method and easy operation. |
