Benefits of technology

The technology described by this patented describes how certain materials can be used on top of an nanosized crystal layer that helps it mix liquids like water and solvents better. This results in improved photoeletronics performance due to increased surface area between them and enhanced interfacial interaction between these layers.

Problems solved by technology

Technological Problem addressed in this patented text relates to improving the performance of solar batteries while reducing its manufacturing process complexity and producing less expensive products. Current methods involve developing better materials like quantum dots instead of crystal ones, making these alternatives difficult because they require higher temperatures during synthesis leading to decomposition and evaporation. Additionally, there may also exist issues related to compatibility with other chemical substances used within the battery itself.

Embodiment 1

[0019] Mix 165 mg of zinc oxide nanowires with 10 ml of 120 g / L nano-titanium dioxide colloidal dispersion evenly. Then the colloid was coated on the dense titanium dioxide film, baked at 450° C. for 30 minutes, and the coating and firing process was repeated until a nano-sized titanium dioxide crystal film with a thickness of 10 microns was obtained. This thin film electrode was immersed in hot (75°C) 0.5 mol / L hydrochloric acid solution for 48 hours until the ZnO nanowires were completely removed. Soak the electrode in a titanium tetrachloride solution, then bake it at 450°C for 15 minutes, and then place the electrode at 3×10 -4 Sensitization by soaking in mol / L Z907 dye in acetonitrile and butanol solution for 12 hours.

[0020] The dye-sensitized titanium dioxide nanocrystalline film prepared above is used as the cathode, the conductive glass coated with the platinum layer is used as the counter electrode, and a quasi-solid electrolyte is used to assemble the battery. T...

Embodiment 2

[0025] Mix 100 mg of aluminum hydroxide nanorods with 10 ml of 100 g / L nano-titanium dioxide colloidal dispersion evenly. Then the colloid was coated on the dense titanium dioxide film, baked at 600° C. for 10 minutes, and the coating and firing process was repeated until a nano-sized titanium dioxide crystal film with a thickness of 15 microns was obtained. This thin film electrode was immersed in hot (75°C) 0.5 mol / L NaOH solution for 40 hours until the AlOH nanorods were completely removed. The electrode was soaked in a titanium tetrachloride solution, and then baked at 300°C for 40 minutes, and then the electrode was heated at 10 -5 Sensitize by immersing mol / L N3 dye in acetonitrile and butanol solution for 20 hours.

Embodiment 3

[0030] Mix 50 mg of iron oxide nanowires with 10 ml of 120 g / L nano-titanium dioxide colloidal dispersion evenly. Then the colloid was coated on the dense titanium dioxide film, baked at 350° C. for 30 minutes, and the coating and firing process was repeated until a nano-sized titanium dioxide crystal film with a thickness of 10 microns was obtained. This thin film electrode was immersed in hot (75°C) 0.5 mol / L hydrochloric acid solution for 48 hours until the iron oxide nanowires were completely removed. The electrode was soaked in a titanium tetrachloride solution, and then baked at 400 °C for 30 minutes, and then the electrode was heated at 10 -5 Sensitization by immersion in mol / L N3 dye in acetonitrile and butanol solution for 8 hours.
