Problems solved by technology

Ordinary laminators are bulky, complex in structure, and poor in precision, and are only suitable for the external film lamination protection of silicon cells, not suitable for the sealing of dye-sensitized solar cells.

Embodiment Construction

[0027] See attached drawing, 1—lower vacuum chamber, 2—electric heating plate, 3—silica gel plate, 4—silica gel sealing ring, 5—upper cover plate (upper vacuum chamber), 6—three-way valve, 7—support platform, 8—battery panel.

[0028] A method for laminating and sealing a dye-sensitized solar cell, characterized in that:

[0029] a) First place the positive and negative battery plates on the electric heating plate in the vacuum chamber of the laminator, and place a soft, flat and elastic film between the upper and lower positive and negative plates; through heat conduction and heat radiation heating the electrode plate;

[0030] b) Next, close the cover plate of the vacuum chamber, and then vacuumize the vacuum chamber. The pressure difference between the inside and outside of the vacuum chamber makes the upper and lower positive and negative plates squeeze the film in the middle, and at the same time through heat conduction and heat radiation to the electrodes plate is heat...

Abstract

The invention discloses a dye sensitization solar cell sealing method and a device thereof which are suitable for sealing dye sensitization solar cells of various structures. In a sealed vacuum chamber, a laminated battery heating platform fixed by electric insulation and thermal insulation materials is employed to heat a seal film in a molten cell, and through a method of controlling air pressure difference to enable a flexible press glue film to complete gas extrusion in sealing space in the dye sensitization solar cell, problems of difficult extraction of a bubble between cell pole plates, easy heat radiation of the heating platform and large temperature change are solved.

Description

technical field [0001] The invention relates to a method for lamination and sealing of solar cell components, in particular to a special laminator for dye-sensitized solar cell components. Background technique [0002] In 1991, the laboratory of the Ecole Polytechnique de Lausanne in Switzerland reported the research results of a new dye-sensitized solar cell in Nature (O’Regan, Graetzel.M, 1991, 353, 737), which immediately attracted widespread international attention and attention. [0003] Dye-sensitized solar cells are mainly composed of the following parts: photoanode, nanoporous semiconductor film, dye photosensitizer, electrolyte and counter electrode. [0004] Since the two electrodes of the battery need to be pressed into a whole, the battery sealing pressure is an important issue. Ordinary laminators are bulky, complex in structure, and poor in precision, and are only suitable for the external film lamination protection of silicon cells, not suitable for the seal...
