Embodiment 1

[0032] Example 1, see figure 1 , figure 2 , a flexible photovoltaic solar cell, including two flexible photovoltaic solar cell units, the flexible solar cell unit includes a flexible battery substrate 1, a semiconductor material layer 2 and a light-receiving layer 3, and a conductive bus bar 4 is arranged on the light-receiving layer In two adjacent flexible photovoltaic solar cell units, the conductive bus bar of the light-receiving layer of one flexible solar cell unit overlaps with the edge of the flexible battery substrate of the other flexible solar cell unit, and realizes ohmic connection to the overlapped part.

[0033] The preparation method is as follows: firstly, a flexible thin-film photovoltaic solar cell unit is prepared, and the flexible thin-film photovoltaic solar cell unit includes a flexible battery substrate 1, a semiconductor material layer 2 and a light-receiving layer 3 sequentially stacked from bottom to top; Conductive bus bars 4 are formed by bonding...

Embodiment 2

[0037] Embodiment 2, the same or similar technical content as in Embodiment 1 will not be described one by one in this embodiment. In this example, the material 4 of the conductive bus bar is copper with a diameter of 0.1 mm. The conductive bus bar is directly bonded to the light-receiving layer after being infiltrated by the transparent conductive adhesive, and the ohmic connection method of the overlapping part of the bus bar and another battery unit is conductive adhesive catch.

Abstract

The invention provides a film photovoltaic solar cell component and a manufacturing method thereof. A flexible solar cell comprises at least two flexible photovoltaic solar cell units. Each of the flexible photovoltaic solar cell units comprises a flexible battery substrate, a semiconductor material layer and a light receiving layer which are orderly stacked. The light receiving layer is provided with a conductive bus bar. The series connection mode of the two adjacent flexible photovoltaic solar cell units is that ohmic connection is formed between the conductive bus bar of one flexible photovoltaic solar cell conductive bus bar and the substrate of the other flexible photovoltaic solar cell to realize series connection. The invention also discloses a manufacturing method of an interconnected type flexible solar cell. The process operation is simple, ohmic contact is easy to form, and the safety performance is good.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and relates to a flexible thin-film photovoltaic solar cell assembly and a manufacturing method thereof, in particular to an interconnected flexible photovoltaic solar cell and a manufacturing method thereof. Background technique [0002] At present, solar cells that have been commercially applied mainly include crystalline silicon solar cells and thin-film solar cells; kind. The substrates of thin-film solar cells can be divided into rigid substrates and flexible substrates. For example, glass substrates are rigid substrates, and stainless steel substrates are flexible substrates. Solar cells with flexible substrates are essentially divided into two categories, one is to use laser or mechanical methods to divide the whole battery into small battery cells connected in series or parallel, but the substrate of this type of solar cells is not Separated, this kind of overall division into small...
