Embodiment 1

[0038] One, the preparation method of the dye-sensitized solar cell capable of generating electricity in rainy days with high adsorption and high stability according to the present invention specifically comprises the following steps:

[0039] 1. Dissolve natural graphite powder, sodium nitrate and potassium permanganate in concentrated sulfuric acid with a mass fraction of 98% in an ice bath at a mass ratio of 1:1:5, and stir for 5 to 10 minutes.

[0040] 2. Remove the ice bath, heat the solution to 35°C, stir for 30-40 minutes, then add 60-100 mL of deionized water and 10-20 mL of 30% hydrogen peroxide until the bubbles disappear.

[0041] 3. Centrifuge the solution at a speed of 7200rpm for 30 minutes, and wash until the pH of the supernatant is 3 to 4. The obtained mixture is dispersed in water again and ultrasonicated for 15 to 20 minutes, and then centrifuged at a speed of 3000rpm for 3 minutes to remove the black color The residue was obtained as a homogeneous suspensio...

Abstract

The invention provides a dye sensitized solar cell capable of generating electricity on rainy days, preparation method and application thereof. The graphene oxide is deposited on an ITO conductive glass substrate by electrophoresis and is reduced to form a graphene electrode, and a pair electrode is deposited on an FTO conductive glass substrate or a platinum sheet is taken as a pair electrode to be combined with a dye sensitized solar cell to form a novel solar cell. The high stability, good conductivity, and high cation adsorptivity of grapheme are fully utilized, and through creative design, the performance of generating electricity on rainy days is endowed to the dye sensitized solar cell. The preparation method of the solar cell capable of generating electricity on rainy days is simple, the performance is stable, and the cost is low.

Description

technical field [0001] The invention belongs to the field of solar cells, and relates to a dye-sensitized solar cell capable of generating electricity in rainy days, a preparation method and application thereof. Background technique [0002] At present, solar cells still occupy an important position in economic development, but because of their limited use conditions, they can only be used in sunny days and with sufficient light. Therefore, finding a new type of high-efficiency solar cell that can adapt to different weathers is an urgent need important issues to solve. Graphene has good adsorption properties to cations in rainwater, and the dye-sensitized solar cells compounded with graphene overcome the problem of not being able to generate electricity in rainy days. Therefore, the development of dye-sensitized solar cells that can generate electricity in rainy days has important theoretical significance and Practical value. Contents of the invention [0003] The purpos...
