Problems solved by technology

[0005] The methods for forming the light-transmitting region in the prior art include laser etching process, wet etching process, dry etching process, stripping process, etc., but laser etching equipment is expensive, and as the size of thin-film solar cell substrates continues to increase, The higher the cost of laser etching equipment, the higher the production cost will be; the wet etching process, dry etching process, and stripping process are all more complicated, the control is difficult, and it is not suitable for high-quality mass production

Embodiment 1

[0021] Such as figure 1 As shown, the manufacturing method of the thin film solar cell module with light transmission of the present invention includes:

[0022] S11, positioning the mask on the back electrode of the thin film solar cell module;

[0023] S12, sandblasting and etching the mask to form a light-transmitting region in the thin film solar cell module.

[0024] The process of forming the light-transmitting area by the mask-assisted sandblasting etching process is as follows: figure 2 As shown in the schematic diagram, the thin-film solar cell module includes an insulating and transparent substrate 11 , a transparent electrode layer 12 , a semiconductor layer 13 , and a back electrode layer 14 . Position and cover the pre-processed patterned mask plate 21 on the back electrode layer 14, sandblast the mask plate 21 by the sandblasting equipment 22, control the depth of sandblasting and etching by the control unit, and place the back electrode layer 14 After the se...

Embodiment 2

[0030] On the basis of embodiment one, in order to further improve product quality, as Figure 5 The flow chart of the process method for manufacturing the light-transmitting thin-film solar cell module shown in this embodiment, after forming the light-transmitting region, also includes:

[0031] S21, providing an isolation line along the outer side of the light-transmitting area.

[0032] Such as Image 6 The front schematic view of the light-transmitting thin-film solar cell module is shown, and the light-transmitting regions 50 in the figure are equal-spaced parallel straight-line open grooves. In the process of forming the light-transmitting region 50 using the sand-blasting etching process for the opening groove of this shape, the sandblasting 23 may accumulate at the edge of the light-transmitting region 50, because the sandblasting 23 usually contains metal particles, and in addition, the sandblasting During the process, the etched metal electrodes will produce a larg...

Abstract

The invention discloses a film solar battery module with transparence and a process method thereof. In the process method, a mask assisted sand-blasting etch process is used for forming a transparent area, and the process method specifically comprises the following steps of: positioning and covering a mask on a back electrode of the film solar battery module; and performing sand-blasting etching on the mask to ensure that the transparent area is formed on the film solar battery module. By using the process method of the invention to manufacture the film solar battery module with transparence, the transparent area with any patterns can be formed, and the production cost is low, and the process method is suitable for mass production.

Description

technical field [0001] The invention relates to the field of thin-film solar cells, in particular to a light-transmitting thin-film solar cell module and a process method thereof. Background technique [0002] Solar photovoltaic power generation is a relatively mature technology in renewable energy and has broad development prospects. However, the current high production cost of photovoltaic power generation has become the main factor restricting its large-scale commercialization. This is because silicon materials for manufacturing solar cells are expensive, and ordinary silicon solar cells need to consume more silicon materials. [0003] Thin-film solar cells are generally considered to be the most promising next-generation photovoltaic technology because of their low silicon consumption and simple process, which can greatly reduce production costs. In addition, due to the beautiful appearance and good heat insulation effect of thin-film batteries, more and more urban buil...
