Description

A kind of DSSC module

Technical field

The present invention relates to integrated module, especially a kind of DSSC module by large-area DSSC (DSC) formation.

Background technology

From the M. of the Institute of Technology such as Lausanne, SUI height in 1991

Since the report of professor laboratory, DSC is no matter obtaining large development aspect research or the practical application foreground.Present small size (＜1cm ²) photoelectric conversion efficiency of DSC reaches as high as 11.1, light is in the commercial applications research of the research work of the large-area product of this technology and this technology is also extensively carried out in the world.In view of the principle of this solar battery technology and structure are different from conventional silica-based solar cell, thus the preparation of the module of this battery and assembling procedure can't be fully with reference to the production process of the silica-based solar cell of routine.The assembling of silica-based solar cell module adopts the mode of lamination to carry out at present, for realizing that at fusing eva film under the situation that guarantees certain temperature and pressure the connection between the element cell finally is assembled into module.DSC is a sandwich structure, inside battery is filled with liquid electrolyte, and packaging film is a kind of hot melt film simultaneously, thereby can not carry out the lamination encapsulation, for research and the application that advances large-sized DSC battery, design and study for the necessity that is assembled with of DSC module.

Summary of the invention

The purpose of this invention is to provide a kind of DSSC module, can be fit to the preparation of a large amount of large tracts of land, high efficiency DSC module, and the output performance of battery modules can be adjusted easily as required.

For achieving the above object, the technical solution used in the present invention is:

A kind of DSSC module, comprise at least 2 solar cells, its special feature is, described every solar cell is installed on the outer box of 1 battery, the outer box of this each battery all detachably is installed on the crossbeam, thereby on crossbeam, be provided with preformed hole and can pass the battery plus-negative plate lead, all crossbeams are installed in one and have in the module housing of cover plate, pull box on the cover board is installed, be provided with the positive and negative electrode binding post in pull box, this positive and negative electrode binding post is connected with corresponding solar cell by the preformed hole on the crossbeam by lead.

Its middle cross beam has 2 at least, and box outside 2 batteries is installed on each crossbeam at least, can form a plane thereby be between the crossbeam to removably connect after connection.

Wherein all have connecting hole in each crossbeam both sides.

Wherein module housing and cover plate are as a whole, and the module housing is connected by securing member between the beam with weighing apparatus.

Wherein the outer box of battery is a square box, wherein be provided with fixed supported slab on three limits at this square box, on each fixed supported slab, all have the support plate connecting hole, described solar cell is stuck between this square box and fixed supported slab and by fluid sealant and is connected with square box, thereby relevant position all has the hole that cooperates with the aforementioned fixation support plate and is connected with box outside the battery by securing member in the middle of each crossbeam.

Independently outer box is equipped with in each element cell outside in the battery modules of the present invention, can effectively realize the secondary encapsulation of DSC element cell by the embedding of sealant, the outer box of several element cells is fixed on the horizontal crossbeam, preformed hole is left in order to draw the both positive and negative polarity of battery in the crossbeam back side, mutual snapping between each crossbeam, can disassemble at any time, not only can reach good mechanics effect, each lateral cell of battery modules can be changed flexibly simultaneously.And the output performance of battery module can be adjusted as required easily.

Embodiment

The present invention will be further described in detail below in conjunction with accompanying drawing:

The present invention comes down to single solar cell is contained in the outer box 1 of battery, then the outer box 1 of a plurality of batteries is fixed on a plurality of crossbeams 4, again all crossbeams 4 are linked up again and be encapsulated into a big battery modules by the module housing 7 of being with backboard, because the quantity and the lead of outer box 1 of battery and crossbeam 4 are connected and can adjust voluntarily as required, therefore can fully satisfy and use needs.

As Fig. 1,2,3,4, shown in 5, battery modules of the present invention, comprise that (promptly have only on a crossbeam 4 and this crossbeam 4 only has under the situation of 2 installation sites at least 2 solar cells, usually should be in actual the use) more than 4 solar cells, every solar cell is installed on the outer box 1 of 1 battery, the outer box 1 of this each battery all is installed on the crossbeam 4 removably, thereby on crossbeam 4, be provided with preformed hole 5 and can pass the battery plus-negative plate lead with the solar cell relevant position, all crossbeams 4 are installed in the module housing 7, this module housing 7 also is a square box, this module housing 7 is an integral body with the cover plate 8 of rear surface of solar cell, and the side is fixing by bolt and crossbeam 4.Pull box 9 is installed on cover plate 8, is provided with positive and negative electrode binding post 10 in pull box 9, this positive and negative electrode binding post 10 is connected with corresponding solar cell by the preformed hole 5 on the crossbeam 4 by lead.
