Abstract
The utility model relates to a back contact solar cell module. The back contact solar cell module is formed by an ETFE film, an EVA adhesive film, a back contact solar cell, a printed circuit board and an EVA adhesive film, all of which are arranged from up to down in a laminated manner. The housing is arranged outside and around the back contact solar cell module. The back contact solar cell is in welded fastening with the printed circuit board. A loop is formed by the back contact solar cell in series connection with a corresponding circuit arranged on the printed circuit board. The end part of the loop is provided with a circuit outgoing line. The circuit outgoing line is connected with a surface-mounted diode arranged on the printed circuit board. The whole structure of the back contact solar cell module is more compact, the processing technology of the product is simpler, the cost is reduced, the weight is light, and the back contact solar cell module is convenient to transport and carry.
Description
Technical field
The utility model relates to field of photovoltaic power generation, relates in particular to a kind of back contact solar cell assembly.
Background technology
Photovoltaic module is widely used as a kind of device of solar generating.In order to can be good at utilizing solar power generation, people develop a kind of solar module of carrying on the back contact, the solar module of this back of the body contact is combined from top to bottom by photovoltaic glass, backing, back contact solar cell or ETFE film, photovoltaic glass, back contact solar cell, and back contact solar cell is exported electric energy by conducting copper belt.But this back contact solar cell assembly overall weight is heavier, be not easy to carry, and between back contact solar cell, void ratio is larger, product processing technique is complicated, and production cost is high.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of compact conformation is provided, and the light and handy portable back contact solar cell assembly of total quality.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of back contact solar cell assembly, by ETFE film, EVA glued membrane, back contact solar cell, printed circuit board and EVA glued membrane from top to bottom lamination form, its outside surrounding is provided with shell; Described back contact solar cell and printed circuit board are welded and fixed, and this back contact solar cell is connected into loop by the corresponding circuits being arranged on printed circuit board, this end, loop is provided with circuit lead-out wire, and described circuit lead-out wire is connected with the stamp-mounting-paper diode being arranged on printed circuit board.
Compared with prior art, usefulness of the present utility model is: this back contact solar cell assembly overall structure is compacter, and product processing technique is simpler, cost, and quality is light and handy, is convenient to transportation and carries.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model back contact solar cell assembly section partial structurtes schematic diagrames;
Fig. 2 is that the utility model back contact solar cell assembly is overlooked internal structure schematic diagram.
In figure: 1, ETFE film; 2,2-1, EVA glued membrane; 3, back contact solar cell; 4, printed circuit board; 4-1, corresponding circuits; 4-2, stamp-mounting-paper diode; 5, shell; 6, circuit lead-out wire.
embodiment:
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of back contact solar cell assembly shown in Fig. 1, Fig. 2, by ETFE film 1, EVA glued membrane 2, back contact solar cell 3, printed circuit board 4 and EVA glued membrane 2-1 from top to bottom lamination form, its outside surrounding is provided with shell 5; Shown in back contact solar cell 3 directly directly weld with position corresponding on printed circuit board 4, by circuit 4-1 corresponding on printed circuit board 4, make back contact solar cell 3 be connected into loop, this end, loop is provided with circuit lead-out wire 6, and described circuit lead-out wire 6 is connected with the stamp-mounting-paper diode 4-2 being arranged on printed circuit board 4; This stamp-mounting-paper diode 4-2 can protect the hot spot in back contact solar cell assembly.
This back contact solar cell assembly is by being arranged on corresponding circuits 4-1 and the stamp-mounting-paper diode 4-2 on printed circuit board 4, substitute the use of conducting copper belt in original scheme, can make solar module overall structure compacter, product processing is simpler; Adopt the lamination mode of ETFE film 1, EVA glued membrane 2, back contact solar cell 3, printed circuit board 4 and EVA glued membrane 2-1, substitute the assembled scheme of conventional photovoltaic glass and backing or ETFE film and photovoltaic glass, greatly reduce the weight of assembly, make it lighter and handier, be easy to carry.
It is emphasized that: be only preferred embodiment of the present utility model above, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
