Photovoltaic cell substrate pattern manufacturing method

Abstract

The invention discloses a photovoltaic cell substrate pattern manufacturing method, which comprises the steps of designing a manufacturing a pattern in advance according to a pattern manufacturing requirement of a photovoltaic cell substrate, and performing mirror image processing on the designed manufacturing pattern; scribing self-adhesive paper according to the manufacturing pattern subjected to mirror image processing so as to transfer the manufacturing pattern to the self-adhesive paper; adhering the self-adhesive paper to a carrier with a flat surface to obtain a mask plate; and pastingthe mask plate and a photovoltaic cell substrate together, and manufacturing a pattern on the photovoltaic cell substrate through lasers. According to the technical scheme, self-adhesive paper is scribed with a manufacturing pattern subjected to mirror image processing, the self-adhesive paper is pasted on a carrier to obtain a mask plate, and the mask plate and laser are utilized to perform pattern manufacturing on a photovoltaic cell substrate, so that the precision of the pattern manufactured on the photovoltaic cell substrate can be improved on the premise of not influencing the power generation performance of the photovoltaic cell substrate, and the pattern manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pattern making, and more specifically, relates to a method for making a pattern of a photovoltaic cell substrate. Background technique [0002] BIPV (Building Integrated Photovoltaic) is a technology that integrates solar power (photovoltaic) products into buildings. In the construction of BIPV, it is necessary to make patterns on the photovoltaic cell substrate including the substrate, transparent conductive film layer, power generation film layer, and conductive layer in sequence, and then package the patterned photovoltaic cell substrate to make the final photovoltaic cell The components not only have the function of power generation, but also have aesthetics. [0003] At present, the following two methods are often used to make patterns on the substrate of photovoltaic cells: the first method is to make patterns on the glass in advance by inkjet printing or screen printing to obtain patterned glass, ...

AI Technical Summary

Problems solved by technology

In the above-mentioned first method, when the photovoltaic cell substrate is generating electricity, the pattern on the patterned glass will block the photovoltaic cell substrate and cause a hot spot effect on the photovoltaic cell substrate, which will affect the power generation performance of the photovoltaic cell substrate

In the second method, the production cost of the spray-painted glass mask plate is relatively high, and because the ink has flow and diffusion, the edge of the spray-painted pattern will be blurred during spray-painting, and this will have a negative impact on the surface of the photovoltaic cell substrate. The accuracy of the pattern will be affected; the production cost of metal or plastic mask is also relatively high, and the limitation of machining pattern customization is relatively large, and it is impossible to make complex and fine patterns
