Abstract

The invention discloses a preparation method for a high-haze composite transparent conductive electrode. The method comprises the following steps that (1) a cracking liquid is prepared; (2) a cracking template is prepared; (3) a metal film is deposited; (4) a cracking template is removed; (5) a metal oxide is deposited; (6) an etching liquid is prepared; and (7) a composite film is etched to obtain the high-haze composite transparent conductive electrode. The electrode prepared by the method is higher in the haze, can effectively scatter incident light, greatly enhances light absorption of a film cell semiconductor layer, increases the short-circuit light current density, and finally improves the photoelectric conversion efficiency of a solar cell; and in addition, the composite electrode also has the advantages including low surface resistance, higher light transmittance and high environmental stability.

Description

technical field [0001] The invention belongs to the technical field of preparation of transparent conductive electrodes, and in particular relates to a method for preparing a high-haze composite transparent conductive electrode. Background technique [0002] The transparent conductive front electrode is an extremely important part of solar cells, which has a significant impact on the short-circuit current and fill factor of solar cells. Generally speaking, a transparent conductive electrode means that the transmittance to the spectrum of the incident light wavelength range between 380nm and 780nm is greater than 80%, and the resistivity is lower than 10. -3 Ω·cm film electrode. In 1907, Badeker reported the translucent conductive CdO material for the first time. It was not until the Second World War that transparent conductive thin film materials received enough attention and application. Nowadays, transparent conductive thin film materials (such as ITO (Indiumtinoxide), ...
