Problems solved by technology
[0002] Flexible solar cell modules are generally connected in series by multiple solar cell modules, and adjacent solar cell modules are generally connected by a shingled structure or a parallel seam welding structure. The shingled structure makes the flexible solar cell modules connected as a whole. The strength is poor, the stress on the solar cell module is large, and the reliability is poor, and the parallel seam welding structure is easy to cause damage to the solar functional layer in the solar cell module

The invention discloses a flexible solar cell module and a manufacturing method thereof, the flexible solar cell module comprises at least two solar cell modules and a buffer connection structure, each solar cell module comprises a surface electrode, a solar functional layer and a conductive substrate which are stacked in sequence, and the buffer connection structure comprises a first conductive layer, an insulating layer and a second conductive layer; one end of the first conductive layer is integrally connected with a surface electrode of a solar cell module, and one end of the second conductive layer is integrally connected with a conductive substrate of the solar cell module; the conductive substrate of the other solar cell module is provided with an exposed part, the buffer connectionstructure is bent in the extending direction and turned over to enable the first conductive layer to be connected with the exposed part of the other solar cell module, stress buffer can be achieved,and connection is stable and reliable; and the first conductive layer and the exposed part at the welding point are made of different materials from the solar cell functional layer, so that heat borneby the solar cell functional layer is not easily conducted to the solar cell functional layer during welding, and the welding yield is improved.
Description
technical field [0001] The invention relates to the technical field of flexible semiconductors, in particular to a flexible solar cell assembly and a manufacturing method thereof. Background technique [0002] Flexible solar cell modules are generally composed of multiple solar cell modules connected in series, and adjacent solar cell modules are generally connected by a shingled structure or a parallel seam welding structure. The shingled structure makes the flexible solar cell modules integrally connected. The strength is poor, the solar cell module is subject to large stress, and the reliability is poor, and the parallel seam welding structure is likely to cause damage to the solar functional layer in the solar cell module. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a flexible solar cell module, which can buffer stress and has stable an...
