Embodiment 1
[0041] The first step is to use the ultrasonic cleaning method to clean the FTO transparent conductive glass cut into 2.5cm×2.5cm with deionized water, ethanol, and acetone for 15 minutes. After cleaning, dry it with nitrogen, and then perform plasma treatment for 10 minutes. .
[0042] In the second step, 0.4263g of isopropyl titanate and 0.1577g of diethanolamine were dissolved in 3ml of ethanol, and stirred for 15min to prepare dense TiO 2 The solution. Take 100 μL of this solution, spin-coat the treated FTO transparent conductive glass at 7000 rpm for 60 s, and then place it on a heating platform at 500 ° C for 2 h.
[0043] The third step, the mass ratio is TiO 2 Slurry: ethanol = 1:4 ratio configured to prepare porous TiO 2 The solution was ultrasonically oscillated for 30 min. Take 80 μL of this solution on glass / FTO / bl-TiO 2 The substrate was spin-coated at 2000rpm for 30s, and then placed on a heating platform at 550°C for 30min.
