DETAILED DESCRIPTION [0039] Exemplary embodiments of the disclosure will now be described in detail with reference to the drawings in which, the same or similar reference signs refer to the same or similar elements or elements with the same or similar functions. It should be understood that the embodiments described below with reference to the drawings are merely illustrative, and are used only for the purpose of explaining, instead of limiting, the disclosure.
[0040] According to an aspect of the present disclosure, as shown in Fig. 1, an exemplary embodiment of the disclosure provides a self-powered heating assembly 100 including a light transmitting top sheet 1, a power generation layer 2, a back electrode layer 3, an insulating layer 4 and a back sheet 5 sequentially, wherein a conductive heating layer 6 is disposed between the insulating layer 4 and the back sheet 5 and deposited
- 4 2018101361 17 Sep 2018 on the back sheet 5 or the insulating layer 4. The power generation layer 2 may be a flexible thin film solar cell, and preferably a CIGS cell.
[0041] The self-powered heating assembly 100 provided in the exemplary embodiment of the present disclosure is formed by providing a multilayer structure, and since the self-powered heating assembly is internally provided with a conductive heating layer, condensation and freezing on a surface of the self-powered heating assembly can be effectively prevented.
[0042] In an exemplary embodiment of the disclosure, the back sheet 5 may be fixed onto a building by a mounting structure 200 (shown in Figs. 2 and 3) . The insulating layer 4 may be an insulating film attached onto the back sheet 5. At this time, the self-powered heating assembly 100 has a two-layer structure. In another exemplary embodiment of the disclosure, the insulating layer 4 may be formed by a back sheet glass which is fixedly connected to the back sheet 5 and peripheries of the light transmitting top sheet 1 by a structural adhesive. Then the self-powered heating assembly 100 has a three-layer structure, thus improving strength of the self-powered heating assembly 100 .
[0043] The light transmitting top sheet 1 provides a coating surface for the power generation layer 2 while protecting the power generation layer 2 . The power generation layer 2 is attached to the light transmitting top sheet 1 via a coating. In an exemplary embodiment of the disclosure, the light transmitting top sheet 1 may implement an ultra-clear smooth glass, and may have a thickness of 3-4 mm, preferably 3.2 mm.
[0044] As an example of the power generation layer, the thin film solar cell has certain light transmitting performance, which can be scribed into strips according to daylight requirements to further improve the light transmitting performance. Typical transmittance is 10%-50%, and typical power generation capacity is 80W/m2.
[0045] The back electrode layer 3 is a metal compound layer which is sputtered on the power generation layer 2 by a PVD (Physical Vapor Deposition) process. The back electrode layer 3 has a function of collecting current generated by the photovoltaic material, and has light transmittance.
[0046] The conductive heating layer 6 is formed by adhering a metal oxide of an element such as aluminum, zinc, indium or
- 5 2018101361 17 Sep 2018 the like onto the back sheet 5 or the insulating layer 4 by a PLD/PVD (Pulsed Laser Deposition/Physical Vapor Deposition) process. A transmittance of the conductive heating layer 6 may be changed by changing a thickness of the metal oxide film layer. Metal oxides have electrical resistance properties (each block is equivalent to one resistor) . In other words, the conductive heating layer 6 is an oxide having electrical resistance properties, and the oxide may be an oxide of aluminum, zinc, and/or indium. The metal oxide will generate heat after energization. By changing an overall resistance value by changing an area of the metal oxide film layer and a series-parallel relationship between adjacent film layer blocks, a heat generation value is finally changed after energization. A typical operating voltage is 36 V, and a typical heating power is 50W/m2.
[0047] In an exemplary embodiment of the disclosure, the back electrode layer 3 and the conductive heating layer 6 are light transmissive so that light may be supplied through the self-powered heating assembly 100.
[0048] In an exemplary embodiment of the disclosure, as shown in Figs. 2 and 3, the self-powered heating assembly 100 further includes a junction box 7 disposed on a side of the self-powered heating assembly 100. The mounting structure 200 preferably includes a cavity, and the junction box 7 may be disposed in the cavity. The mounting structure 200 is preferably made of an aluminum alloy and may have a broken bridge heat insulation structure .
[0049] In an exemplary embodiment of the disclosure, as shown in Fig. 4, the junction box 7 is provided with a temperature controller, a voltage regulation circuit and an energy storage battery; the temperature controller is configured to control on/off of the voltage regulation circuit according to a temperature of the conductive heating layer 6, and the temperature controller may be a temperature relay. The voltage regulation circuit is configured to supply power to the conductive heating layer 6 and charge the energy storage battery after adjusting a voltage output by the power generation layer 2 to a standard voltage.
[0050] Lead wires of the conductive heating layer 6 and the power generation layer 2 may both be received in the junction box 7 which may be attached to a periphery of the self-powered heating assembly 100 by a structural adhesive. A box body of the junction box 7 is filled by sealant, thereby having greater
- 6 2018101361 17 Sep 2018 dustproof and waterproof performance. When the temperature is lower than a predetermined temperature, the temperature controller generates an on/off signal, so that the voltage regulation circuit is activated to operate; when the temperature rises to the predetermined temperature, the voltage regulation circuit stops working. A typical predetermined temperature is 0°C (return difference being 5°C) · The voltage regulation circuit is configured to convert a voltage output by the power generation layer 2 into a stable DC power with a typical value of 36 V, supply power to the conductive heating layer 6 and charge the energy storage battery at the same time with a typical output power of 60W. The energy storage battery may adopt lithium battery, thus having a better working performance of low temperature resistance. A typical design is 36V20Ah.
[0051] According to another aspect of the disclosure, there is provided a method for producing a self-powered heating assembly, the method including the steps of S1-S5.
[0052] At step SI, arranging a light transmitting top sheet .
[0053] Specifically, the light transmitting top sheet 1 is arranged on a platform.
[0054] At step S2, arranging a power generation layer 2 on a surface of the light transmitting top sheet 1.
[0055] Specifically, the power generation layer 2 may be a flexible thin film solar cell, and preferably a CIGS cell. The light transmitting top sheet 1 provides a coating surface for the power generation layer 2 so that the power generation layer 2 is attached to the surface of the light transmitting top sheet 1 via a coating.
[0056] At step S3, arranging a back electrode layer 3 on a surface of the power generation layer 2 facing away from the light transmitting top sheet 1.
[0057] Specifically, the back electrode layer 3 is a metal compound layer which is sputtered on the surface of the power generation layer 2 facing away from the light transmitting top sheet 1 by a PVD (Physical Vapor Deposition) process, thus having a function of collecting current generated by the photovoltaic material, and being light transmissive.
[0058] At step S4, arranging an insulating layer 4 on a surface
- 7 2018101361 17 Sep 2018 of the back electrode layer 3 facing away from the power generation layer 2.
[0059] At step S5, arranging a back sheet 5 on a surface of the insulating layer 4 facing away from the back electrode layer .
[0060] Specifically, the insulating layer 4 may be an insulating film attached onto the back sheet 5. At this time, the self-powered heating assembly 100 has a two-layer structure. Alternatively, the insulating layer 4 may be formed by a back sheet glass which is fixedly connected to the back sheet 5 and peripheries of the light transmitting top sheet 1 by a structural adhesive. Then the self-powered heating assembly 100 has a three-layer structure, thus improving strength of the self-powered heating assembly 100.
[0061] In an exemplary embodiment of the disclosure, the conductive heating layer 6 is deposited on one of surfaces of the insulating layer 4 and the back sheet 5 facing each other. The conductive heating layer 6 is formed by adhering a metal oxide of an element such as aluminum, zinc, indium or the like onto the back sheet 5 or the insulating layer 4 by a PLD/PVD (Pulsed Laser Deposition/Physical Vapor Deposition) process. A transmittance of the conductive heating layer 6 may be changed by changing a thickness of the metal oxide film layer. Due to electrical resistance properties (each block is equivalent to one resistor) , the metal oxide will generate heat after energization. By changing an overall resistance value by changing an area of the metal oxide film layer and a series-parallel relationship between adjacent film layer blocks, a heat generation value is finally changed after energization. A typical operating voltage is 36 V, and a typical heating power is 50W/m2.
[0062] The method for producing a self-powered heating assembly provided in the present disclosure further includes step S6.
[0063] At step S6, disposing a junction box 7 on a side of the self-powered heating assembly 100.
[0064] Specifically, the junction box 7 may be disposed at any side of the self-powered heating assembly 100 and provided with a temperature controller, a voltage regulation circuit and an energy storage battery; the temperature controller is configured to control on/off of the voltage regulation circuit according to a temperature of the conductive heating layer 6, and the
- 8 2018101361 17 Sep 2018 temperature controller may be a temperature relay. The voltage regulation circuit is configured to supply power to the conductive heating layer 6 and charge the energy storage battery after adjusting a voltage output by the power generation layer to a standard voltage.
[0065] It should be noted that an order of the above steps S1-S5 is not limited herein as long as a self-powered heating assembly stacked by a multilayer structure can be formed. For example, step S4 may be performed after S5.
[0066] The self-powered heating assembly produced by the above method has a multilayer structure, and since the self-powered heating assembly is internally provided with a conductive heating layer, condensation and freezing on the surface of the self-powered heating assembly can be effectively prevented.
