Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] A kind of method of making double-layer solar energy printed screen of the present invention comprises the following steps:

[0034] S1: laser or etching to make the first layer of solar panels

[0035] Use laser cutting process or etching process to carve out the opening pattern of the solar screen on a metal plate with a certain thickness. Wherein, the metal plate can be all metal plates that can be used for laser cutting, such as stainless steel plate, nickel plate, nickel-iron plate, etc., and its thickness is 15um-200um; the opening pattern includes the main pattern of main grid lines ...

Abstract

The invention discloses a method for manufacturing a double-layer solar energy printing screen. The method for manufacturing the double-layer solar energy printing screen comprises the steps that: S1: a first-layer solar energy screen is manufactured by laser or etching, wherein an opening graph of the solar energy screen is carved on a certain thickness of metal plate in a hollowing manner by utilizing a laser cutting process or an etching process; S2: the screen is preprocessed, wherein processing procedures of oil removing, acid washing, water scrubbing, and abrasive blasting are carried out on the metal plate obtained from the step S1; and S3: a second screen is manufactured by electroforming, wherein a photosensitive film layer is uniformly pasted on the surface of the metal plate, graphic areas are exposed and developed, and thus the photosensitive film of a non-graphics areas are removed, the developed metal plate is put in an electroforming groove to be electroformed, and then a film stripping and cleaning process is carried out, so that manufacture of the double-layer solar energy printing screen is accomplished. According to the double-layer solar energy printing screen provided by the invention, a smooth solar-battery electrode fine grid line can be printed, good current collection and transmission capability are achieved, and the solar energy conversion efficiency is improved effectively.

Description

[0001] technical field [0002] The invention belongs to the technical field of solar screen manufacture, and in particular relates to a method for manufacturing a double-layer solar printing screen. [0003] Background technique [0004] In today's world, the research progress of clean energy is accelerating day by day. As the source of most of the energy on the earth, solar energy plays an important role in the research of clean energy. The development of solar cell technology is getting faster and faster. Although its cost is much higher than that of traditional forms of power generation such as thermal power, in the 21st century when a low-carbon economy is vigorously advocated, research on solar cell technology will play an important role in the field of energy research. . [0005] With the continuous development of solar cell technology, the industry has put forward higher technical requirements for the conversion efficiency of solar cells. The conversion efficie...
