Abstract
The present invention relates to a method for integrating a solar cell unit (3) into a product (5) by means of injection molding._The method comprises placing the solar cell unit (3) in an injection molding tool (1) having a mold cavity (2) designed to form a frame around the solar cell unit 3, feeding a thermoplastic material to the mold cavity (2), and cooling the thermoplastic material so that it forms a molded frame around the edge of the solar cell unit (3). Thus, the solar cell unit can be integrated directly into structural parts in products, such as headbands for headphones.
Description
A method for integrating a solar cell unit into a product by means of injection molding Technical field The present invention relates to a method for integrating a solar cell unit into a product bymeans of injection molding.
Background There is a desire to integrate solar cells into consumer products, such as bags, casings, cloths,and headbands for headphones.
A problem is that it is hard to integrate light absorbing materials (solar cells) in applicationswhere frames and other rigid method cannot be used because of the function of the endproduct. For example, headbands, sports equipment and parts of clothing or bags, which needto be flexible and durable.
Summary lt is an aim of the present invention to at least partly overcome the above problems, and toprovide an improved method for integrating a solar cell unit into a product.
This aim is achieved by a method as defined in claim 1.
According to the invention, the method comprises attaching the solar cell unit to the productby means of injection molding.
Injection molding can also be named in-mold injection. The injection molding is, for example,double-injection molding.
With this technology, the solar cell unit can be integrated directly into structural parts inproducts, such as headbands for headphones.
According to an embodiment of the invention, the method comprises placing the solar cellunit is in an injection molding tool and casting a thermoplastic frame on the edges ofthe solarcell unit.
Brief description of the drawings The invention will now be explained more closely by the description ofdifferent embodimentsof the invention and with reference to the appended figures.
Fig. 1 shows a cross-section of a molding tool having a cavity housing a solar cell unit.Fig. 2 shows a cross-section of an example of a solar cell unit having a molded frame on theedges ofthe solar cell unit.
Fig. 3 shows a perspective view of an example of a product including a solar cell unit having amolded frame.
Detailed description Figure 1 shows a cross-section of a molding tool 1 having a mold cavity 2 housing a solar cellunit 3. The molding tool is used for injection molding. The mold cavity 2 is designed to form aframe around the edges of the solar cell unit 3. The shape of the mold cavity 5 can vary anddepends on the shape of the product that the solar cell is to be integrated into. During theinjection molding, melted material is injected into the mold cavity 2 ofthe molding tool 1. Thematerial is, for example, thermoplastic or thermosetting polymers. The material is cooled andhardened to the configuration of the cavity. The molded part is ejected from the mold cavity2 when it has been cooled and hardened.
Figure 2 shows the result of the injection molding with the molding tool 1 shown in figure 1.The solar cell unit 3 has been provided with a molded frame 4 arranged around the edges ofthe solar cell unit 3. The molded frame can be the product itself. Alternatively, the moldedframe is used to integrate the solar cell into the product.
Figure 3 shows a perspective view of an example of a product 5 including a solar cell unit 3having a molded frame 4. The product can, for example, be used in headbands forheadphones. lt is also possible to use double injection molding, also called double shot molding, or two-shot molding. Double injection molding is a manufacturing process used to producecomplicated molded parts from two different materials by molding plastic around an object,in this case around the solar cell unit.
The solar cell unit can be a flexible sheet comprising a solar cell unit and an encapsulationmade of a transparent material enclosing the solar cell.
The solar cell may comprise a flexible insulating substrate extending through the entire solarcell unit, a first conducting layer disposed on one side of the flexible substrate, a secondconducting layer disposed on the opposite side ofthe flexible substrate, a light-absorbing layerarranged on top of the first conducting layer, and a conducting medium for transferringcharges between the second conducting layer and the light-absorbing layer. The solar cell unitfurther comprises encapsulation made of a transparent and fusible material enclosing thesolar cell. The encapsulation is, for example, made of a plastic material, such as polyethylene.The solar cell unit 3 is designed as a sheet having one or more edges. The shape of the solarcell unit may vary. The solar cell 1 is, for example, a solar cell of the type disclosed inEP3598465A1.
The present invention is not limited to the embodiments disclosed but may be varied andmodified within the scope ofthe following claims.
Claims (2)
1. A method for integrating a solar cell unit (3) into a product (5), characterized in that themethod comprises integrating the solar cell unit (3) into the product (5) by means of injectionmolding.
2. The method according to claim 1, wherein the method comprises placing the solar cell unit(3) in an injection molding tool (1) having a mold cavity (2) designed to form a frame (4) aroundthe solar cell unit 3, feeding a thermoplastic material to the mold cavity (2), and cooling thethermoplastic material so that it forms a molded frame (4) around the edge of the solar cellunit (3).
