Embodiment 1

[0068]The ITO electrode 1 is ultrasonically cleaned with detergent plus deionized water and acetone in sequence, and then the ITO electrode 1 is treated with ultraviolet light. Then if Figure 4 As shown, perform the following steps:

[0069] (a) On the ITO electrode 1, PS nanospheres with a size of 100 nm are prepared as a nanostructure layer 2 (such as Figure 5 as shown in a);

[0070] (b) Using PS nanospheres as a template, corrode the ITO electrode 1 with hydrochloric acid, and rinse off the residual hydrochloric acid on the electrodes and nanospheres with deionized water after 2.5 minutes of corrosion;

[0071] (c) Remove the PS nanospheres with ultrasound in chloroform, then ultrasonically clean them in isopropanol for 15 minutes, and dry them with nitrogen to obtain a patterned ITO electrode 10 (such as Figure 5 as mentioned in b);

Embodiment 2

[0080] The ITO electrode 1 is ultrasonically cleaned with detergent plus deionized water and acetone in sequence, and then the ITO electrode 1 is treated with ultraviolet light. Then carry out the following steps to prepare the patterned electrode 10:

[0081] (a) Spin-coating method (2500rpm, 30s) on the ITO electrode 1 to prepare SiO with a size of 200nm 2 Nanospheres as nanostructures 2;

[0082] (b) Due to the conditions of (a), SiO prepared on ITO 2 Nanospheres are not SiO forming close contacts 2 Nanosphere layer, but there is a larger gap between the nanosphere and the nanosphere, so it is not necessary to reduce the size of the nanosphere ( figure 2 In (b) step), it can be prepared in SiO 2 After the nanospheres, the SiO 2 Nanospheres are used as templates to prepare metal thin film layers;

[0083] (c) Using magnetron sputtering method to SiO 2 The nanosphere is used as a template to prepare a Cr layer with a thickness of 150 nm on the ITO electrode 1 as the m...

Abstract

The invention discloses a preparation method for a patterned electrode. The preparation method comprises the following steps of: (1) covering the surface of the electrode by using a nano-structured layer, wherein the coverage rate of the nano-structured layer on the surface of the electrode is 15 to 100 percent; (2) corroding the electrode by using the nano-structured layer as a template; and (3) removing the nano-structured layer to obtain the patterned electrode. The preparation method is simple, and nicks on the surface of the patterned electrode are easy to control. The invention discloses the patterned electrode obtained by the preparation method. By the patterned electrode, the optimization of the morphological structure of an organic light active layer can be induced in the preparation process of an organic solar cell, so that the performance of the organic solar cell can be improved, and the photoelectric energy conversion efficiency of the solar cell can be improved. The invention also discloses the organic solar cell. The organic solar cell can be efficiently manufactured, and the cost is low.

Description

technical field [0001] The invention belongs to the field of organic solar cells, and in particular relates to a patterned electrode, a preparation method and an organic solar cell. Background technique [0002] Solar energy is an inexhaustible and inexhaustible renewable energy source for human beings. Solar cells that convert solar energy into electrical energy based on the photovoltaic effect have received more and more attention. Compared with inorganic solar cells, organic solar cells have unique advantages: low cost, easy processing (can be processed by low-temperature solution methods such as spin coating and printing), and easy to obtain large-area flexible devices. However, the photoelectric energy conversion efficiency (PCE) of organic solar cells is still very low (1 order of magnitude lower than that of inorganic solar cells), which has become a bottleneck hindering its industrialization. [0003] In order to improve the PCE of organic solar cells, the device st...
