Embodiment 1

[0034] Example 1: Preparation of organic-inorganic hybrid solar cells by zinc oxide nanorods

[0035](1) Preparation of one-dimensional zinc oxide nanomaterials: Divide the ITO conductive glass into small pieces of 1.2cm×1.2cm, cover and etch with scotch tape, the etching area is preferably 0.3cm×1.2cm, and the etching solution is the volume fraction 15% hydrochloric acid. After the etching is completed, ultrasonically wash with deionized water, acetone, and isopropanol for 15 minutes respectively. Drop a few drops of seeded ethylene glycol methyl ether sol on the dry conductive glass surface, spin-coat at 3000rpm for 60s, and calcined at 300°C for 20min. The concentrations of zinc acetate and ethanolamine in the seed sol are both 0.75M. Inverted growth of ZnO nanorods in a hydrothermal kettle (see figure 1 ), the concentrations of zinc nitrate and hexamethylenetetramine in the growth solution were both 25mM, and the growth conditions were 92°C for 90min. Cool for 1 hour ...

Embodiment 2

[0040] Example 2: Preparation of organic-inorganic hybrid solar cells by dye-modified nanorod HSC

[0041] The steps of etching, washing, seed layer preparation of ITO conductive glass, preparation of one-dimensional zinc oxide nano-semiconductor material, and heating pretreatment are the same as those in Example 1. The pure organic dye D205 was chosen for the sensitization of one-dimensional nanomaterials. Soak the prepared one-dimensional zinc oxide nanomaterial in D205 dye solution with a concentration of 0.3mM, take it out after 1h, rinse the excess dye on the surface, and dry it. Spin-coat P3HT solution, mask, vapor-deposit silver electrodes, and other steps are the same as in Example 1.

[0042] like Figure 5 As shown, the organic-inorganic hybrid solar cells prepared by using the zinc oxide one-dimensional materials in Examples 1 and 2 as photoanodes have higher photoelectric conversion efficiency than bulk heterojunction hybrid cells and double-layer structure hybri...

Abstract

The invention provides an organic / inorganic hybrid solar battery and a preparation method thereof and belongs to the technical field of hybrid solar batteries. The overall structure layers of the organic / inorganic hybrid solar battery are sequentially as follows: a transparent conductive substrate, an zinc oxide crystal seed layer, a one-dimensional zinc oxide and organic semiconductor material mixed layer, an organic semiconductor layer and a metal film, According to the solar battery structure, the solar battery is prepared layer by layer; and during metal film preparation, a adhesive tape masking process is adopted; and the photoelectric conversion efficiency of the obtained solar battery is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of hybrid solar cells, and in particular relates to an organic-inorganic hybrid solar cell prepared by using a one-dimensional zinc oxide nanometer material as a photoanode. Background technique [0002] Global energy shortages, environmental pollution, and climate warming are increasingly plaguing human society. "Searching for green alternative energy to achieve sustainable development" has become a common topic faced by countries all over the world. Solar energy has become an ideal alternative energy source due to its advantages such as "infinity" of reserves, universality of existence, and cleanness of development and utilization. Therefore, all countries have invested huge financial and material resources to develop more new materials to prepare "zero-emission" green solar cells. Among them, new organic-inorganic hybrid solar cells (HSC) have become the most eye-catching research direction in the field ...
