Embodiment 1

[0018] The electrochemical deposition process was carried out in a 0.01 mol / L zinc nitrate aqueous solution. The power supply used was a two-electrode system with a constant voltage of 2.5 V, a constant temperature of 75 °C, and a deposition time of 20 min. The FTO glass substrate is connected to the cathode, and the anode is made of pure platinum, and the two electrodes are kept parallel with a distance of 2 cm. After the deposition was completed, all samples were washed repeatedly with deionized water to remove residual solution ions on the samples. Afterwards, the samples were placed in an air atmosphere heat treatment furnace for annealing at 150 °C. Subsequently, the sample was placed on an AALD (atmosphere atomic layer deposition) workbench at a temperature of 150 °C. The sample stage was placed 50 mm below the gas delivery pipe at 40 °C, and was repeatedly oscillated at a speed of 50 mm / s. Diethylzinc is used as the precursor of zinc, and pure water is used as the...

Abstract

The invention relates to a manufacturing method for a ZnO nano tree array/polymer blend conformal structure hybrid solar cell and belongs to the technical field of solar cells. The method includes the steps that (1), a ZnO nano rod trunk grows on a conducting glass substrate; (2), atmosphere atomic layer deposition is performed on a sample obtained after electrolytic deposition; (3), the sample is placed in a water solution for chemical bath deposition after seed layer deposition; (4), polymer spin coating is performed; (5), metal Ag electrodes are evaporated. According to the manufactured ZnO nano tree-based conformal structure hybrid solar cell, electrons are transmitted in the axial direction of the nano rod trunk, and the transmission direction of electron holes in polymers is perpendicular to the trunk; in this way, the advantages that in the solar cell formed by assembling nano rod arrays, electron and electron hole transmitting channels are directly connected, and permeation of the polymers is convenient can be kept, besides, the maximum thickness of the polymers can not limit the height of the nano rod arrays, the loading quantity and interface area of the polymers are effectively increased, and due to the structure, performance manifestation of the polymer solar cell is facilitated better.

Description

technical field [0001] The invention relates to a method for preparing ZnO nano tree base / blend polymer conformal structure hybrid solar cells on transparent conductive glass, which belongs to the technical field of solar cells. Background technique [0002] Solar energy accounts for more than 99% of the total energy of the earth. As a pollution-free and inexhaustible energy source, it has become the focus of solving the energy crisis. Organic solar cells have the advantages of wide sources of raw materials, low cost, high environmental stability, flexible and simple preparation process, etc., and have attracted increasing attention. However, compared with inorganic solar cells, the conversion efficiency is significantly lower, and low carrier mobility is an important reason. . By mixing inorganic nanomaterials, taking advantage of the advantages of high carrier mobility and good chemical stability of inorganic nanomaterials, retaining the characteristics of good flexib...
