Embodiment 1
[0017] In Example 1 of the present invention, the application of the above-mentioned silver nanowire composite solar cell hole transport material in a solid-state dye-sensitized cell is taken as an example.
[0018] Its concrete preparation steps are:
[0019] Step 1, in the fluorine-doped SnO 2 The surface of conductive glass (FTO) is coated with a layer of sticky P25 titanium dioxide colloid by scraping method, and then heat-treated in a muffle furnace at 450 ° C for 30 minutes to obtain a porous titanium dioxide film; finally soak it in 4 × 10 -4 Soak in the organic solution of the dye of mol / L for 8 hours, obtain the dye-sensitized solar cell photoanode;
[0020] Step 2, in the hole transport material that the Spiro-OMeTAD chlorobenzene solution that has 200ul is made into, add the silver nanowire (concentration is 20mg / ml) that 50ul is dispersed in the chlorobenzene solution (here, because in the Spiro that has 200ul -In the hole transport material made of OMeTAD chloro...
Embodiment 2
[0024] In Embodiment 2 of the present invention, the application of the above-mentioned silver nanowire composite solar cell hole transport material in a solid quantum dot solar cell is taken as an example.
[0025] Its concrete preparation steps are:
[0026] Step 1, in the fluorine-doped SnO 2 The surface of conductive glass (FTO) is coated with a layer of sticky P25 titanium dioxide colloid by scraping method, and then heat-treated in a muffle furnace at 450°C for 30 minutes to obtain a porous titanium dioxide film;
[0027] Step 2, adopt continuous ion layer adsorption reaction (SILAR) to deposit CdS quantum dots on the porous titanium dioxide film, the specific method is to first immerse the porous titanium dioxide film in 0.05M Cd(NO)3 4H2O methanol solution for 60s, and then use methanol Cleaning; then immerse in 0.05M Na2S·9H2O methanol solution for 60s, then wash with methanol; cycle soaking 9 times, put in a vacuum drying oven at 70°C for 4 hours;
[0028] Step 3, ...
Embodiment 3
[0032] In Embodiment 3 of the present invention, it is taken as an example to apply the above-mentioned silver nanowire composite solar cell hole transport material to a perovskite solar cell.
[0033] Its concrete preparation steps are:
[0034]Step 1, adopt the hydrothermal synthesis method to prepare anatase type titanium dioxide nanoparticles, its preparation process is as follows: adopt tetraisopropyl titanate [Ti(i-OC3H7)4], nitric acid (HNO3), glacial acetic acid (CH3COOH) and deionized water (H2O) as raw materials, control the molar ratio of Ti(i-OC3H7)4, HNO3, CH3COOH and H2O to be 1:2.8:1:76; first Ti(i-OC3H7)4 is dissolved in H2O, Add CH3COOH under strong stirring, then slowly add HNO3 while stirring; then heat the reaction system to 80°C and transfer it to an autoclave, and react hydrothermally at a temperature of 150-300°C and a pressure of 0-330Mpa to obtain titanium dioxide sol ; Finally, the titanium dioxide sol is treated with vacuum water removal, and then t...
