Embodiment 1
[0029] 1. Use the known silver salt method to set a silver metal grid on the PET substrate. The thickness of the grid silver line is 4 μm, the width is 40 μm, and the spacing is 2 mm; the polyurethane filler is filled in the mesh by scraping; A polythiophene conductive polymer film with a thickness of 200 nm was then coated to obtain a flexible transparent conductive substrate with a sheet resistance of 0.12Ω / □ and a transmittance of 65.21%.
[0030] 2. take by weighing the nano-titanium dioxide P25 powder that 2.4g Degussa produces and put into the mortar that fills the n-butanol of 15ml, then add 8g ethyl cellulose solid content and be that the n-butanol solution of 10% and 4g PEG20000 solid content are 20% methanol solution, mix well and grind for 4h to make TiO 2 slurry. Print it on the surface of the above-mentioned flexible transparent conductive substrate, and get about 12 μm thick TiO after drying naturally. 2 film. Then put it under a 500W UV lamp for 0.5h to prepa...
Embodiment 2
[0034]1. Use the known magnetron sputtering method to set a copper metal grid on the PET substrate. The thickness of the grid copper wire is 1.2 μm, the width is 80 μm, and the spacing is 4.9 mm; Filling with gelatin filler; and then coating a polypyrrole conductive polymer film with a thickness of 60.5nm to obtain a flexible transparent conductive substrate with a sheet resistance of 5.25Ω / □ and a transmittance of 78.12%.
[0035] 2. Use Zn(Ac) 2 2H 2 O prepared to 0.2mol L -1 Anhydrous ethanol solution, after reflux at 90°C for 4 hours, add LiOH·H at 0°C 2 O powder, so that the concentration is 0.3mol L -1 , stirred at this temperature for 25 minutes to form a colloidal solution of ZnO nanoparticles. Centrifuge in a high-speed centrifuge for 20 minutes, add absolute ethanol to the precipitated ZnO nanoparticles to wash, and then wash with a dilute nitric acid solution with pH=4 to obtain ZnO nanoparticle powder with a particle diameter of 10 nm. Then put it into a morta...

[0039] 1. Use the known etching method to set a copper metal grid on the PET substrate. The thickness of the grid copper wire is 6 μm, the width is 5.1 μm, and the spacing is 0.12 mm; the grid is filled with polyvinyl alcohol by scraping Filler; then coat a polythiophene conductive polymer film with a thickness of 198nm to obtain a flexible transparent conductive substrate with a sheet resistance of 9.62Ω / □ and a transmittance of 82.69%.
[0040] 2. Weigh 3.6g of 1mol / L tetrabutyl titanate n-butanol solution and 1.2g of Degussa’s nano-titanium dioxide P25 powder and stir for 6 hours to obtain TiO 2 colloid. It was printed on the conductive layer of the organic conductive polymer film, and after natural drying, a TiO with a thickness of about 14 μm was obtained. 2 film. Then it was boiled in pure water at 100°C for 4h to obtain nano-TiO 2 porous film.
[0041] 3. The prepared TiO 2 The porous film is dipped into a 4 x 10 -5 mol / L of Z907 dye in absolute ethanol, after ads...
