Embodiment 1

[0042] See image 3 , the special-shaped solar photovoltaic curtain wall glass is trapezoidal, and the trapezoidal solar cell core board is used as the photoelectric interlayer of the photovoltaic curtain wall glass. The cell core board includes multiple solar cell modules connected in parallel. The production steps are as follows:

[0043] Step 1: Process the window layer glass (or outer layer glass 1): Process the window layer glass according to the shape of the curtain wall glass, and the light transmittance of the glass must meet the performance requirements of the photovoltaic module.

[0044] Step 2: Clean the window layer glass: Clean the window layer glass with alcohol or acetone.

[0045] Step 3: Cover the glass with a PVB sealing film 2, which is also called an adhesive material.

[0046] Step 4: Make the photoelectric interlayer of special-shaped photovoltaic curtain wall glass from the solar cell core board, the steps are as follows:

[0047] Laser scribes the fr...

Embodiment 2

[0067] See Figure 4 , the special-shaped solar photovoltaic curtain wall glass is trapezoidal, and the trapezoidal solar cell core board is used as the photoelectric interlayer of the photovoltaic curtain wall glass. The cell core board includes multiple solar cell modules connected in series. The manufacturing steps are as follows:

[0068] The method of the first step to the third step is with embodiment 1.

[0069] Step 4: Make the photoelectric interlayer of special-shaped photovoltaic curtain wall glass from the solar cell core board, and the process is as follows:

[0070] The laser scribes the front electrode layer of the battery core board, and scribes the front electrode layer into four areas, A, B, C, and D, or four solar cell modules. The laser frequency used is 5.0-8.0KHz;

[0071] Scribing the sub-cells with a laser in the area so that the effective area of ​​each sub-cell is the same, so that the current of the sub-cells of the battery assembly is the same;

Embodiment 3

[0081] Make the trapezoidal solar photovoltaic curtain wall glass with a curved waist, and use the trapezoidal solar cell core board with a curved waist as the photoelectric interlayer of the photovoltaic curtain wall glass.

[0082] Use a laser to scribe the amorphous silicon solar cell core board, divide it into multiple regions (also known as amorphous silicon solar cell components), each region has the same number of sub-cells, and multiple amorphous silicon solar cell components Connect in parallel to make the voltage of each area consistent, forming a trapezoidal amorphous silicon solar cell core board with a radian at the waist, which is used as a photoelectric interlayer of solar photovoltaic curtain wall glass. The manufacturing method of the trapezoidal photovoltaic curtain wall glass with radian at the waist is the same as that in Example 1. The positive and negative electrodes of each amorphous silicon solar cell core board are drawn in parallel from the corners by ...

Abstract

The invention relates to an abnormal solar energy photovoltaic curtain wall glass and a manufacturing method thereof; the abnormal solar energy photovoltaic curtain wall glass comprises an inner layer glass and an outer layer glass, and is characterized by also comprising an abnormal photovoltaic interlayer; the photovoltaic interlayer is a photovoltaic array formed by a solar energy battery component, the solar energy battery component is formed by series connected sub-batteries with same effective area or parallel connected sub-batteries with same amount and voltage on a large-scale integrated solar energy battery core board, an insulated separated wire is arranged between neighboring solar energy battery components, and positive and negative electrodes of the battery component are led out by a conductive strip to output and supply power. The beneficial effect is as follows: the shortcomings in the prior art that a plurality of amorphous silicon solar energy battery components are needed for completing series or parallel connection are solved directly from the structure design and technology of the large-scale integrated solar energy battery core board, the solar cell battery core boards with various shapes are applicable to the building of photovoltaic curtain walls with large area and various shapes, and meet the electrical performance of photovoltaic construction.

Description

technical field [0001] The invention relates to a special-shaped solar photovoltaic curtain wall glass, which is widely used in various shapes of photovoltaic glass curtain walls and belongs to the technical field of photovoltaic building integration. Background technique [0002] At present, the variety of appearance shapes of glass curtain wall buildings highlights that the solar cell modules used in glass curtain walls are too single in shape, basically square or rectangular. If these single-shaped solar cell components are used, it is difficult to make solar photovoltaic curtain wall glass components with irregular planes to meet the structural requirements of special-shaped glass walls. Therefore, how to break through the irregular shape of photovoltaic curtain wall glass components must first start with the technological progress of solar photovoltaic curtain wall glass. For example, Chinese patent ZL200420093384.8 discloses hollow glass solar cell modules, which solv...
