     In some cases, the photovoltaic layer, the light-adjusting layer, the light-emitting layer, the first infrared-reducing layer, or the second infrared-reducing layer cannot completely occupy the entire area of the laminated structure, resulting in a gap between adjacent layers. Therefore, the layer which is incompletely filled is provided with thermoplastic filling material.

     Moreover, the window assembly further comprises an external storage device, wherein the controller is configured to determine whether the power generated by the photovoltaic layer is greater than the power required by the light-adjusting layer and/or the light-emitting layer, and if the result of determination is yes, then to provide part of power to the external storage device. 
     The light-adjusting layer and/or the light-emitting layer are composed of a plurality of independently controllable portions, and the controller is further configured to respectively provide power to the plurality of independently controllable portions of the light-adjusting layer and/or the light-emitting layer.

     providing a first power to the light-adjusting layer; 
     providing a second power to the light-emitting layer.

     DETAILED DESCRIPTION 
     A plurality of embodiments of the present disclosure is described below with reference to the drawings. 
       FIGS.  1 - 16    respectively show various possible particular configurations of the laminated structural assembly of the present disclosure. 
     In the description of the present disclosure, the terms “upper” and “lower” refer to the vertical orientations in the drawings of the specification. The term “transverse” refers to the horizontal direction in the drawings of the specification. The term “width” refers to the dimension in the horizontal direction in the drawings of the specification. The term “area” refers to the surface area in the horizontal direction in the drawings of the specification. 
     In addition, in the present disclosure, the terms “first”, “second” and similar terms are merely used to distinguish the same technical terms for the ease of description, and do not imply or hint any sequence or orientation. In addition, in different embodiments, exemplary solutions, or described structures, even the same terms do not necessarily indicate that the structures are certainly the same. 
     According to the present disclosure, a laminated structure assembly is provided, and comprises an optional reflection-reducing layer/anti-fouling layer/anti-scratch layer, an upper-layer transparent substrate, an optional photovoltaic layer, an optional first infrared-reducing layer, an optional light-adjusting layer, a light-emitting layer, an optional second infrared-reducing layer and a lower glass, wherein adjacent layers are bonded to each other through a bonding layer. 
     An embodiment of the present disclosure may comprise a combination of the photovoltaic layer, the light-adjusting layer, and the light-emitting layer. Another embodiment of the present disclosure may comprise a combination of the photovoltaic layer and the light-emitting layer. Alternatively, another embodiment of the present disclosure comprises a combination of the light-adjusting layer and the light-emitting layer. 
     The upper-layer transparent substrate and the lower-layer transparent substrate are preferably glasses. The upper glass is preferably a glass with a high light transmittance, so as to transmit more light. The lower glass is preferably a glass with a low light transmittance, so as to provide a relatively soft lighting environment. Alternatively, those skilled in the art can understand that the upper-layer and lower-layer transparent substrates may be made of other transparent materials. 
     The reflection-reducing layer/anti-fouling layer/anti-scratch layer may be directly coated on the upper surface of the upper glass. The reflection-reducing layer, the anti-fouling layer, and the anti-scratch layer may be coatings independent of each other, for example, the reflection-reducing layer, the anti-fouling layer, or the anti-scratch layer coated on the upper surface of the upper glass. Alternatively, the reflection-reducing layer/anti-fouling layer/anti-scratch layer may be a coating that integrates at least two functions of reflection-reducing, anti-fouling, and anti-scratch, which can be determined as required in different embodiments. For example, in the combination of the light-adjusting layer and the light-emitting layer, the reflection-reducing layer may be left out, or a composite coating that has the reflection-reducing function may not be provided. 
       FIG.  17    shows a structure of the reflection-reducing layer, which further has an anti-fouling function. The reflection-reducing layer shown in  FIG.  17    comprises a porous layer  1  provided on the upper surface of a glass substrate  3  and a plurality of particles  2  provided in the porous layer. The porous layer  1  is made of a pore-forming polymer, which is selected from PMMA, nitrocellulose, cellulose acetate butyrate or polyvinyl alcohol. The particles  2  are made of silicon dioxide, titanium dioxide, aluminum oxide or zirconium oxide. The reflection-reducing layer shown in  FIG.  17    is commercially available from Saint-Gobain Glass. 
       FIG.  18    shows a structure of the anti-fouling layer, which further has an anti-scratch function. The anti-fouling layer shown in  FIG.  18    comprises a framework layer  5  provided on the upper surface of a glass substrate  4  which has a plurality of openings  6 . The framework layer  5  is made of silicon oxide, aluminum oxide or titanium oxide. The openings  6  can be formed by arranging sacrificial particles in the framework layer. The sacrificial particles can be made of high molecular polymers, such as polymethyl methacrylate or polystyrene. The anti-fouling layer shown in  FIG.  18    is commercially available from Saint-Gobain Glass. 
     The photovoltaic layer may be a thin-film photovoltaic layer. The thin-film photovoltaic layer has light-transmitting holes so as to allow light to pass through the thin-film photovoltaic layer. The arrangement pattern of these light-transmitting holes can be set as required. Alternatively, the thin-film photovoltaic layer itself may transmit light. An example of the thin-film photovoltaic layer comprises, but is not limited to, a thin-film solar cell based on amorphous silicon, cadmium telluride, copper indium tin, or copper indium gallium selenide. 
     Alternatively, the photovoltaic layer may be a photovoltaic module based on single crystal or polycrystal semiconductor material. The photovoltaic layer in the present disclosure comprises at least one single crystal or polycrystal semiconductor photovoltaic module. An example of the photovoltaic module comprises, but is not limited to, a photovoltaic module based on single crystal silicon, polycrystal silicon, gallium arsenide, indium gallium phosphide, or indium phosphide. The single crystal silicon photovoltaic module is preferable. 
     The semiconductor material photovoltaic module is generally configured as a light-tight sheet-shaped module. In order to transmit light, the photovoltaic layer is configured to cover part of the area of the laminated structure assembly, for example, the photovoltaic layer may cover the middle part or the edge part, or may be configured as an array of a plurality of modules discretely distributed. 
     Both the first and second infrared-reducing layers may be film-based infrared-reducing layers configured to have a base of PET or other materials and an infrared-reducing material coating provided on the base. For example, products such as the XIR or UCSF series may be available from Saint-Gobain Safety Glass. The side surface with the coating may be arranged to face upward, alternatively, the side surface with the coating may be arranged to face downward. 
     Alternatively, the first and second infrared-reducing layers may just be infrared-reducing material coatings. For example, products such as the KAPPA series, CoolCoat and ClimaCoat are available from Saint-Gobain Safety Glass. 
     The light-adjusting layer is generally configured to have a structure with an upper base and a lower base, so that the bases of the light-adjusting layer are respectively bonded to the adjacent bonding layers. For example, the light-adjusting layer may be a layer having an electrochromic structure, a suspended particle device, a polymer dispersed liquid crystal structure, or a guest-host liquid crystal structure, or any combination thereof. The light-adjusting layer may be configured to have an integral form, that is, to have an integral structure and to be controlled as a whole. Alternatively, the light-adjusting layer can be divided into a plurality of light-adjusting modules, and each light-adjusting module can be independently controlled. Particular structures of the light-adjusting modules may be the same or different. 
     The light-emitting layer may be an active light-emitting layer generally configured to have an upper base and a lower base, so that the two bases may be respectively bonded to the adjacent bonding layers. 
     The active light-emitting layer may have a form of a transparent discrete LEDs-array structure layer in which a plurality of LED light-emitting units is provided. The arrangement of these LED light-emitting units may be determined as required. For example, these LED light-emitting units may be arranged to a particular pattern as required. These LED light-emitting units are configured to be controllable as a whole, or configured to be independently controllable for each light-emitting unit, or configured as a plurality of groups, wherein each group is independently controllable. The LED light-emitting units may be configured to emit light of different colors, or each LED light-emitting unit may emit light of various colors. 
     Alternatively, the active light-emitting layer may have another form of an electro-luminescent structure layer having a plurality of sub-layers, such as a fluorescent layer, a dielectric layer, and a transparent conductive layer. The light-emitting layer may be configured as an electro-luminescent layer having an integral form, that is, the light-emitting layer is a whole and is controlled as a whole. Alternatively, the light-emitting layer is configured to comprise a plurality of separate electro-luminescent structure modules so that each module can be independently controlled. 
     The light-emitting layer may be a passive light-emitting layer being a light-guiding coating directly coated on the surface of the adjacent bonding layer. The light-guiding coating does not completely cover the surface of the bonding layer, so that the surface of the bonding layer provided with the light-guiding coating may still play a role of bonding. Preferably, the light-guiding coating is provided on the lower surface of the adjacent bonding layer. 
     Generally, the light-guiding coating is configured to transmit light from an external light source. In the present disclosure, the light-guiding coating may be configured to transmit light from a plurality of light sources, or transmit light of different colors. The light-guiding coating may be configured to have an integral form or configured to be composed of a plurality of portions. In addition, the passive light-emitting layer may be arranged in a required layout, for example, in a particular shape or the like. The integral light-guiding coating has an integral structure, and may transmit light from a plurality of different light sources. The light-guiding coating composed of a plurality of portions may transmit light separately. 
     In addition, the area of each layer between the upper-layer transparent substrate and the lower-layer transparent substrate is generally small, and therefore, gaps may be formed at the edge portions of each of the intermediate layers. For example, the width and/or length of the light-adjusting layer, the light-emitting layer or the film-based infrared-reducing layer is smaller than those of the upper and lower glasses, so that gaps are formed at the edge portions. Thermoplastic filling material, such as PVB, may be arranged in the formed gaps, so as to keep the dimensions consistent and play a role of sealing the edges. In addition, the unoccupied portion of the crystalline silicon module in the photovoltaic layer may also be filled with thermoplastic material, such as PVB. 
     In addition, PVB material is preferably used for each bonding layer, and EVA, TPO or POE may be used as well. PVB can isolate ultraviolet rays. Preferably, the PVB material used in the present disclosure can isolate ultraviolet rays of the range of  10 - 400 nm.

     In the present disclosure, the combination of the photovoltaic layer, the light-adjusting layer and the light-emitting layer can provide different light and shadow modes and effects as required. 
     For example, the photovoltaic layer shields part of sunlight, and the light passing therethrough forms a pattern according to the arrangement of the photovoltaic layer. For example, the light-transmitting holes of the thin-film photovoltaic layer may be arranged in a circle, a rectangle or other patterns. The shape of the light-transmitting hole is not limited to a circle, and may be various regular or irregular polygons. For another example, in the crystalline silicon photovoltaic layer, the crystalline silicon photovoltaic modules are arranged in the middle, and the light passes through the edge portion; or the crystalline silicon photovoltaic modules are arranged at the edge portion, and the light passes through the middle portion; or the crystalline silicon photovoltaic modules are arranged in an array, and the light passing therethrough presents a grid pattern. 
     The light-adjusting layer can adjust the brightness of light, and achieve overall or partial brightness and/or color changes by controlling all or part of the light-adjusting layer, thereby obtaining various light and shadow effects. For example, an electrochromic light-adjusting layer can adjust the brightness of the light, and a liquid crystal light-adjusting layer can adjust the brightness and color of the light. 
     The active light-emitting layer can be controlled to cooperate with the light passing through the photovoltaic layer and/or the light-adjusting layer to provide different light and shadow effects. For example, a portion shielded by the photovoltaic layer is configured to emit light to supplement the light intensity; or the light-transmitting portion of the corresponding photovoltaic layer is configured to emit light to enhance the contrast of brightness and darkness; or in a background environment darkened by the adjustment of the light-adjusting layer, part of the photovoltaic layer emits light to achieve particular effects, for example, the starry sky effect. 
     The passive light-emitting layer may be configured to guide light transmitted from the photovoltaic layer and produce a required lighting effect. For example, the light-guiding coating may be configured to guide the light transmitted from the edge portion to the middle portion, or transmit the light transmitted from the middle portion to the edge portion, so as to achieve a more uniform lighting effect. For another example, the light-guiding coating may be configured into various patterns as required, so as to form a lighting effect with a pattern. 
     The passive light-emitting layer can further transmit additional light emitted by an external light source, such as LED light sources arranged around the light-guiding coating. These LED light sources can be controlled to achieve different lighting effects. 
     The laminated structure of the present disclosure can thus achieve the coordination of functionality with optical and visual effects. 
     According to a further embodiment of the present disclosure, a window assembly is provided, and comprises the laminated structure assembly according to any one of the embodiments 1-16 and at least one interface configured to be electrically connected to a controller, wherein the controller is configured to provide power generated by the photovoltaic layer and/or external input power to the light-adjusting layer and/or the light-emitting layer according to power required by the light-adjusting layer and/or the light-emitting layer. 
     According to a further embodiment of the present disclosure, a window assembly is provided, and comprises the laminated structure assembly according to any one of the embodiments 1-16 and a controller, wherein the layers of the laminated structure assembly are electrically connected to the controller, and wherein the controller is configured to provide power generated by the photovoltaic layer and/or external input power to the light-adjusting layer and/or the light-emitting layer according to power required by the light-adjusting layer and/or the light-emitting layer. 
     The controller is configured to provide power generated by the photovoltaic layer or input power from an external storage device to the light-adjusting layer and/or the light-emitting layer according to power required by the light-adjusting layer and/or the light-emitting layer. That is, when the power generated by the photovoltaic layer meets requirements of the light-adjusting layer and/or the light-emitting layer, only the power generated by the photovoltaic layer is provided, while when the power generated by the photovoltaic layer cannot meet requirements of the light-adjusting layer and/or the light-emitting layer, the power generated by the photovoltaic layer and the additional power obtained from the external storage device are both provided to the light-adjusting layer and/or the light-emitting layer. The controller is further configured to provide the surplus power generated by the photovoltaic layer to the external storage device when the power generated by the photovoltaic layer cannot be completely consumed by the light-adjusting layer and/or the light emitting layer. 
     As mentioned above, the light-adjusting layer and/or the light-emitting layer may be composed of a plurality of independently controllable portions, and the controller is further configured to respectively provide power to the plurality of independently controllable portions of the light-adjusting layer and/or the light-emitting layer. 
     For example, the power may be provided to all of independently controllable portions of the light-adjusting layer, so that the entire light-adjusting layer operates. Alternatively, the power is only provided to part instead of all of the independently controllable portions of the light-adjusting layer, so that part of the light-adjusting layer operates. 
     For example, the power may be provided to all of independently controllable portions of the light-emitting layer, so that the entire light-emitting layer operates, that is, all of the light-emitting units emit light. Alternatively, the power is only provided to part instead of all of the independently controllable portions of the light-emitting layer, so that part of the light-emitting layer operates, that is, only part of the light-emitting units emits light, and the other part of the light-emitting units does not emit light. 
     The controller is further configured to provide variable power to the light-adjusting layer and/or the light-emitting layer. In an example, uniformly variable power is provided to the entire light-adjusting layer, so as to realize the change of overall light brightness. Alternatively, in another example, individually variable powers are respectively provided to the independently controllable portions of the light-adjusting layer, so as to achieve a different distribution of the light brightness. 
     Similarly, variable power may be provided to the entire light-emitting layer, so as to realize the change of overall light. Alternatively, variable power is respectively provided to the independently controllable portions of the light-emitting layer, so as to achieve a different distribution of the light brightness. 
     In an example, the light-emitting layer in the window assembly may be a passive light-emitting layer, and may further comprise a light source provided at the periphery of the passive light-emitting layer, and the controller is further configured to control said peripheral light source to obtain a required lighting effect. For example, the required lighting effect can be obtained by turning on/off part of the light sources or controlling the luminance of the light sources. The passive light-emitting layer can guide the light emitted by the light sources. 
     The function of the controller may be realized by a hardware circuit, or by a combination of a hardware circuit and executable instructions. For example, the controller may comprise a combination of a micro control unit and a memory, and the micro control unit executed the executable instructions in the memory and controls an execution element to realize the function of the controller. The controller may be configured as other devices capable of executing controlling instructions, such as a programmable gate circuit, a microcomputer, and the like. 
     Alternatively, the controller may be implemented as a hardware circuit. For example, the power generated by the photovoltaic layer and the power from the external storage device can be adjusted by an insulated gate bipolar transistor, and according to an electric signal sent by an external sensor, the power provided to the light-adjusting layer and/or the light-emitting layer is controlled by a switching element such as a relay or other adjusting elements. The electrical elements in the controller can be obtained from commercial sources. 
     Referring to  FIG.  19   , according to another embodiment of the present disclosure, a method for adjusting light-adjusting and/or light-emitting power of a window assembly is further provided. The window assembly may be a laminated structure comprising an optional photovoltaic layer, an optional light-adjusting layer and a light-emitting layer according to any one of the embodiments 1-16. 
     The method comprises: step  10 , obtaining power from the photovoltaic layer; step  20 , determining whether the power generated by the photovoltaic layer is sufficient, and providing the power to the light-adjusting layer and/or the light-emitting layer if the power is sufficient; step  30 , obtaining additional power from external if the power is insufficient; and step  40 , providing the obtained power to the light-adjusting layer and/or the light-emitting layer. 
     The step of providing the obtained power to the light-adjusting layer and/or the light-emitting layer further comprises: providing a first power to the light-adjusting layer, and/or providing a second power to the light-emitting layer. 
     Further, the step of providing the first power to the light-adjusting layer comprises: respectively providing the first power to the plurality of independently controllable portions of the light-adjusting layer; and/or, variably providing the first power to the plurality of independently controllable portions of the light-adjusting layer. 
     Further, the step of providing the second power to the light-adjusting layer comprises: respectively providing the second power to the plurality of independently controllable portions of the light-emitting layer; and/or, variably providing the second power to the plurality of independently controllable portions of the light-emitting layer. 
     The method further comprises: providing the generated surplus power to the external storage device when the power generated by the photovoltaic layer is surplus. 
     It should be noted that there is no sequential restriction to the above steps of the method. For example, the power obtained from the photovoltaic layer may be directly allocated and sent to the light-adjusting layer and/or the light-emitting layer, and it is determined whether the power generated by the photovoltaic layer is sufficient when the power provided to the light-adjusting layer and/or the light-emitting layer needs to be increased. Alternatively, it is determined whether the power generated by the photovoltaic layer is sufficient before providing power to the light-adjusting layer and/or the light-emitting layer, for example, it is determined whether the rated power of the photovoltaic layer is less than the required power of the light-adjusting layer and/or the light-emitting layer, and then additional power is obtained from external, for example, from a battery or an external mains supply, before the power is allocated. Providing power to the light-adjusting layer and/or the light-emitting layer can be performed simultaneously or sequentially, depending on the particular application environment and the required light and shadow effects. 
     In another example of the method, the window assembly only comprises the light-adjusting layer and the light-emitting layer, the power can be obtained directly from external, and the other steps are the same as the previous example of the method. 
     According to another embodiment of the present disclosure, a computer device is provided, and comprises a memory, a processor, and instructions stored in the memory and executable by the processor, wherein the processor implements steps of the method for adjusting light-adjusting and/or light-emitting power of a window assembly when executing the instructions. 
     The computer device may be a device with computing capabilities such as a computer or a smart phone. For example, the computer device may be hardware, a dedicated circuit, software, a firmware, logic, or any combination thereof. In some embodiments, the memory may be a portable computer magnetic disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical storage device, a magnetic storage device, a cloud storage device, or any suitable combination thereof. The processor may be a general processor, a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, a discrete gate or transistor logic device, a discrete hardware component, or any combination thereof. The general processor may be a microprocessor; alternatively, the processor may be any common processor, controller, microcontroller, or state machine. The processor may be implemented as a combination of a plurality of computer devices, for example, a combination of a DSP and a microprocessor, a combination of a plurality of microprocessors, a combination of one or more microprocessors and a DSP core, or any other similar structures. 
     According to another embodiment, a computer-readable medium on which executable instructions are stored is provided, wherein the executable instructions are configured to cause a machine to implement steps of the method for adjusting light-adjusting and/or light-emitting power of a window assembly when executed. 
     The computer-readable storage medium may be a tangible device capable of holding and storing instructions used by an instruction executing device. The computer-readable storage medium may be, but not limited to, for example, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination thereof.

The computer-readable storage medium used here is not interpreted as an instantaneous signal itself, such as radio wave or other freely propagating electromagnetic wave, electromagnetic wave propagating through waveguide or other transmission media (for example, light pulse travelling through optical fiber cables), or an electrical signal transmitting through wires. 
     The computer-readable program instructions described herein may be downloaded from the computer-readable storage medium to various computing/processing devices, or be downloaded to an external computer or an external storage device via a network, such as the Internet, a local area network, a wide area network, and/or a wireless network.

The network adapter card or network interface in each computing/processing device receives computer-readable program instructions from the network, and forwards the computer-readable program instructions to store the computer-readable program instructions in the computer-readable storage medium in each computing/processing device.
