Embodiment 1

[0044] Referring to Figures 1-5, the preparation process is as follows:

[0045] 1) Prepare a composite layer of cloth 1 and polymer film 2 on a laminator, and control the temperature to melt the polymer film.

[0046] 2) Cut out the hole 3 in the upper layer of cloth or cloth / polymer film composite layer corresponding to the light-receiving part of the unit cell (see Figure 1); if the upper layer only has polymer film, it is not necessary to cut the hole.

[0047] 3) Punch holes 6 on the fluoroplastic film 5 around the unit cells 4 that have been encapsulated with the fluoroplastic film (see FIG. 2 ).

[0048] 4) Connect each unit cell with a wire; the wire connection is sealed and protected with epoxy resin (ie, A / B glue).

[0049] 5) Stack the lower layer (cloth, polymer film or polymer film / cloth composite layer) 7, the unit cell sheet 4 and the upper layer (cloth, polymer film or Cloth / polymer film composite layer) 12 materials, so that the light-receiving part of the u...

Embodiment 2

[0055] Its preparation process is similar to embodiment 1, and in embodiment 2, referring to Fig. 5, the polyester cloth (500g / cm2) that will have PU back glue 2 )1 and EVA film (containing 15% VA, cross-linking degree of 85%, thickness of 0.2mm, transparent, fast-curing type) 2 are laminated at 100°C for 3 minutes to form a composite layer in advance. Cut off half of the polyester cloth / EVA film composite layer at the light-receiving position of the corresponding unit cell to form a cavity 3 for use as the upper layer; the other half of the polyester cloth 72 / EVA film 71 composite layer is reserved as the lower layer . Drill holes 6 around the fluoroplastic film 5 of the unit cell sheet 4 encapsulated with the ETFE film. Connect each unit battery piece 4 in the assembly with a flat copper wire, and seal and protect the connection of the wires with epoxy resin (ie, A / B glue). Stack the materials from bottom to top in the following order: Polyester cloth / EVA film composite la...

Embodiment 3

[0057] Its preparation process is similar to embodiment 1, and in embodiment 3, nylon cloth (1000g / cm 2 ) and EVA film (containing 20% ​​VA, 90% cross-linking degree, 0.5mm thick, translucent, fast-curing type) at 90°C for 5 minutes to form a composite layer in advance. Cut out the composite layer at the light-receiving position of the corresponding unit cell sheet in the nylon cloth / EVA film composite layer. Drill round holes around the fluoroplastic film of the unit cells that have been packaged with F30 film. Properly connect each unit cell in the assembly with flat copper wire, and seal and protect the wire connection with epoxy resin (ie A / B glue). Stack the materials from bottom to top in the following order: nylon cloth / EVA film composite layer-unit battery sheet-nylon cloth. Use adhesive tape to stick the light-receiving part of the unit cell. A stainless steel wire with a diameter of 3 mm is placed where the fold is required. First raise the temperature to 100°C a...

Abstract

The invention relates to a portable laminate solar battery, and relative production. Wherein, said battery comprises upper, middle and lower layers; the upper and lower layers are laminated or / and macromolecule films, while at least one layer contains macromolecule film; the middle layer is packed unit battery plate; it uses fused film to prepare laminate macromolecule film composite layer; the part of composite layer relative to the lighted part of unit battery plate has holes; the circumference of middle layer has holes; the unit battery plate is connected by wires; layering lower, middle and upper layers on laminate compressor, to expose the lighted part; using thermal-insulated material to plaster the lighted part of middle layer; at the folded part, arranging narrow rigid object or holing the film; compressing it in compressor; cooling and furnishing edge.

Description

technical field [0001] The present invention relates to a solar cell, in particular to a portable electric device (such as a notebook computer, a portable printer, a lighting device, a communication device, etc.) ) powered portable cloth-based solar cell module and a preparation method thereof. Background technique [0002] Solar photovoltaic power generation is the most promising way of new energy and renewable energy. The most basic components of solar photovoltaic power generation are solar cells, including monocrystalline silicon, polycrystalline silicon, amorphous silicon and thin film batteries. A solar panel consisting of one or more solar cells is called a photovoltaic module, or solar cell module. Due to the economic advantages of amorphous silicon solar cells, its position in the entire solar cell field is rapidly rising, and it has become the focus of energy plans in some developed countries (Ni Meng, M K Leung, K Sumathy, Renewable Energy, 2004, (2): 9~11). ...
