Embodiment 1
[0027] 1. Cleaning of the FTO conductive glass substrate: put the FTO conductive glass into piranha solution (concentrated sulfuric acid and 30% hydrogen peroxide) and soak for 12 hours, then rinse it with deionized water until neutral to obtain a clean FTO conductive glass;
[0028] 2. Prepare 10ml of terpineol / ethanol mixed solvent with a weight ratio of 1:1, then add 0.1g of reduced graphene oxide powder, ultrasonicate for 30min and then magnetically stir for 1h; then add 40ml of 10wt% ethyl cellulose ethanol solution , stirred for 3h; then added 0.6ml acetylacetone and 0.6mlOP emulsifier, stirred until the ethanol was evaporated to dryness, and prepared a carbon nanotube precursor on the FTO conductive substrate;
[0029] 3. Use the screen printing method to print the carbon nanotube precursor on the cleaned FTO glass conductor, place it in a blast drying oven at 100°C for 20 minutes, then place it in a sealed glass petri dish, and place it in a muffle furnace at 400°C Sin...
