Abstract
The utility model provides a multi-segment welding type interconnector structure, which comprises a front surface segment, a connection segment and a back surface segment, wherein the front surface segment, the connection segment and the back surface segment are sequentially connected; the front surface segment comprises a plurality of welding segments and a plurality of U-shaped segments; the welding segments and the U-shaped segments are alternately and sequentially connected; the width of the connection segment is less than that of the back surface segment; and the width of the connection segment is less than that of the front surface segment. The multi-segment welding type interconnector structure is particularly suitable for a silicon chip which has discontinuous battery main gate lines; and as the U-shaped segments are added, the stress between the interconnector and the silicon chip is reduced.
Description
Technical field
The utility model relates to solar cell, particularly, relates to multistage welded type interconnector structure.
Background technology
In solar cell system, the solar panel of arranging in length and breadth consists of the solar panel matrix, generally connect by interconnector between the multi-disc solar panel of same file or same horizontally-arranged, the end of many interconnectors is connected to convergent belt, thus with delivery of electrical energy to load for.
The main grid line of cell panel is a continuous straight line in the prior art, because interconnector is different from the thermal coefficient of expansion of silicon chip, the thermal coefficient of expansion of interconnector is 16.5, and the thermal coefficient of expansion of silicon chip is 2.6, therefore the stress aggravation caused the bending of silicon chip easily after temperature raise.
The utility model content
For defective of the prior art, the purpose of this utility model provides a kind of multistage welded type interconnector structure.
According to an aspect of the present utility model, a kind of multistage welded type interconnector structure is provided, comprises the front segment, linkage section and the dorsal section that link to each other successively, described front segment comprises a plurality of welding sections and a plurality of U-shaped section, wherein, described welding section is connected successively connection with the U-shaped section.
Preferably, the width of described U-shaped section is less than the width of described welding section.
Preferably, described linkage section is wave structure at its longitudinal direction.
Preferably, described linkage section indentation structure on its longitudinal direction.
Preferably, described linkage section and described front segment smooth connection.
Preferably, described linkage section and described dorsal section smooth connection.
Preferably, the width of described linkage section is less than the width of described front segment.
Preferably, the width of described linkage section is less than the width of described dorsal section.
The utility model is particularly useful for the discontinuous silicon chip of cell panel main grid line, owing to added the U-shaped section, so that the stress between interconnector and the silicon chip reduces.Stress after the inconsistent so that temperature of the width of interconnector raises diminishes and economical with materials.
Description of drawings
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 illustrates the structural representation according to multistage welded type interconnector structure of the present utility model;
Fig. 2 illustrates the especially applicable silicon chip electrode surface patterning of the utility model.
Embodiment
