[01] The invention relates to the field of photovoltaic modules, specific to the composite board of photovoltaic power generation, building thermal insulation, and curtain wall decoration.
[02] The current approach for photovoltaic power generation in buildings typically involves rooftop installation or steel keel systems for fagade-mounted photovoltaic curtain walls. However, the limited rooftop space in high-rise buildings poses significant challenges for achieving sufficient solar panel coverage to balance the buildings' electricity demands. Additionally, the use of steel keel systems for facade mounting is not only complex and expensive but also compromises the original thermal insulation properties of the building envelope due to thermal bridges formed by the steel components. Moreover, the uniform dark colour of conventional solar panels fails to meet the aesthetic requirements of diverse building facades.
[03] In response to these issues, this invention proposes a simple and fast-to-install bridge cut-off photovoltaic, thermal insulation, and decoration composite board system for exterior walls. The system integrates photovoltaic power generation, building thermal insulation, and exterior wall decoration in a single panel that can be directly used as an exterior wall material without the need for steel keel systems or other auxiliary maintenance structures. The mentioned composite board system aims to address the limitations of rooftop space in high rise buildings and satisfy the functional requirements of building thermal insulation and decoration.
[04] The composite board comprises a sandwich structure of cadmium telluride photovoltaic glass, insulation layer, and cement-based backing board. The decorative surface can be customized with different colours and patterns to suit specific architectural styles and preferences. By integrating the functions of power generation, thermal insulation, and decoration, the proposed composite board system offers a comprehensive solution to the challenges of photovoltaic power generation in high-rise buildings. This innovation sets it apart from conventional photovoltaic panels and curtain wall systems.
[05] In the context of the increasing trend towards energy conservation, emissions reduction, and renewable energy applications, this invention contributes significantly to achieving environmental, economic, and social sustainability by offering a cost-effective solution. This invention is expected to make a significant contribution towards achieving the goals of zero carbon emissions and renewable energy buildings by 2050 while fulfilling the needs of human well-being.
[06] The purpose of the present invention is to provide a structurally simple and easy-to install bridge-cut-off photovoltaic power generated, thermal insulated and decorative
composite board external wall system, which addresses the above-mentioned problems. To achieve this objective, the technical solution of the present invention is as follows.
[07] The structure of composite board system comprising a composite panel, a building wall, and a connection between the composite panel and the building wall. The composite panel includes cadmium telluride (CdTe) laminated photovoltaic glass layer with an outer surface decorative coating, insulation layer, and cement-based backing layer. The CdTe laminated photovoltaic glass layer and cement-based backing layer are respectively adhered to both sides of the insulation layer. The outer surface of the CdTe laminated photovoltaic glass is attached to a decorative layer. The exterior of the building wall is coated with a mortar leveling layer. The composite panel is connected to the building wall through a dual fixing method of adhesive riveting.
[08] First, the composite panel is riveted to the building wall through aluminium alloy fastener, thermal bridge-cut-off layers, hot-dip galvanized angle steel, and expansion bolts.
[09] Second, the cement-based backing layer of the composite panel is bonded to the outer wall of the mortar leveling layer of the building wall with weather-resistant adhesive.
[10] Further, a hot-dip galvanized angle steel is L-shaped, with one side attached to the mortar leveling layer, and the other side is horizontally set. The first mounting hole is provided on the mortar leveling layer side of the hot-dip galvanized angle steel, in which an anchor is installed. The hot-dip galvanized angle steel is connected to the building wall through the anchor.
[04] Further, the horizontally set side of the hot-dip galvanized angle is provided with the second mounting hole and connected to the aluminium alloy clip bolt through it. Further, the aluminium alloy fastener is horizontally set, with a third mounting hole provided at one end, which is connected to the second mounting hole of the hot-dip galvanized angle steel through a bolt. The top and bottom of the aluminium alloy fastener are provided with mounting grooves to connect with the peripheral edge of the cadmium telluride laminated photovoltaic glass layer in the composite board.
[11] Further, a cold bridge blocking pad is arranged between the aluminium alloy fastener and the hot-dip galvanized Angle steel. The cold bridge blocking pad is arranged between the second installation hole and the third installation hole, and the upper and lower ends of the cold bridge blocking pad are respectively in contact with the aluminium alloy fastener and the hot-dip galvanized Angle steel. Further, the insulation layer is made of fireproof rock wool board.
[12] Further, the thickness of the cold bridge blocking pad is 10-20mm, and the cold bridge blocking pad is made of polyurethane casting glue.
[13] The installation method of the photovoltaic thermal insulation and decoration composite board includes the following steps:
S1. Apply the mortar screed outside the building wall, and then use the anchor parts to fix the hot-dip galvanized Angle steel outside the mortar screed and insert the anchor parts into the building wall after penetrating the mortar screed layer.
S2. Install the first composite panel at the bottom end of hot-dip galvanized Angle steel. The cement-based backing layer in the first composite panel is bonded with the outer side wall of the mortar leveling layer through adhesive.
S3. An aluminium alloy fastener is installed at the top of the first composite panel, and the installation groove at the bottom of the fastener is clamped to the top of the cadmium telluride laminated photovoltaic glass layer in the first composite panel. The other bottom side of the aluminium alloy fastener is bolted to the hot-dip galvanized Angle steel, and a cold bridge blocking pad is arranged between the aluminium alloy fastener and hot-dip galvanized Angle steel.
S4. Install the second composite panel at the upper end of the aluminium alloy fastener, clamp the bottom end of the cadmium telluride laminated photovoltaic glass layer of the second composite panel to the installation groove of the aluminium alloy fastener, and then connect the cement-based backing layer in the second composite panel to the mortar screed layer outside the wall through the adhesive.
[14] Compared to existing technologies, the advantages and positive effects of this invention are as follows:
1, The invention of the composite board system combining the composite panel with the building wall enables the building wall with a photovoltaic power generation effect while providing thermal insulation for the building, simplifying the construction process of the building exterior wall, shortening the construction period, and reducing construction costs.
2, The invention of the composite board system achieving install through anchoring devices, hot-dip galvanized angle steel, and aluminium alloy fasteners, eliminating the need for embedded connectors in the exterior wall of the building and reducing the construction procedures of the exterior wall, thereby reducing the installation difficulty of the photovoltaic module. Furthermore, through the structural design of the aluminium alloy fastener, adjacent composite panels can be structurally connected, further improving the connection stability between the composite panel and the building wall.
3, There is no fixed keel frame in this invention, and it does not need to be connected to embedded parts on the building wall. According to adding cold bridge blocking pads between the aluminium alloy fastener and the hot-dip galvanized angle steel, this invention avoids the thermal bridge from a structural form, optimizing the overall thermal performance and ensuring the thermal insulation effect of the building wall to the greatest extent. Moreover, the use of a keel frame is also avoided, which reduces material and construction costs.
4, The decorative coating on the outer surface of the CdTe laminated photovoltaic glass layer used in this invention can achieve decorative veneers of different colours and textures based on owner's preference, addressing the aesthetic requirements. Compared to existing photovoltaic panel and curtain wall technologies and products, this invention can be flexibly applied to building surface with different materials and design styles, and with lower construction costs.
[15] In order to more clearly illustrate the technical scheme in the embodiments of the invention, a brief introduction of the drawings required to be used in the embodiments or in the description is presented below. It is obvious that the drawings described below are only examples of the invention:

Figure 8 is a schematic diagram of the structure in installation step 4 of the present invention;
[16] As shown in Figures 1 to 4, this embodiment discloses an installation structure of bridge-cutoff photovoltaic power generated, thermal insulated and decorative composite board external wall system, comprising a composite panel, a building wall 4, and the connection between the composite panel and the building wall 4. The composite panel includes cadmium telluride (CdTe) laminated photovoltaic glass layer with an outer surface decorative coating 1, insulation layer 2, and cement-based backing layer 7. CdTe laminated photovoltaic glass 1 and cement-based backing layer 7 respectively adhered to both sides of the insulation layer 2. The outer side of building wall 4 is coated with a mortar leveling layer 3, and the composite panel is connected to building wall 4 through hot-dip galvanized angle steel 9, aluminum alloy fasteners 8, and the cement-based backing layer 7 in the composite panel is bonded to the outer wall of the mortar leveling layer 3 through adhesive 6.
[17] This invention combines photovoltaic components and insulation materials directly, and then combines them with the building wall. As shown in Figure 1, it consists of a building wall, mortar leveling layer, cement-based backing plate, insulation layer, and CdTe laminated photovoltaic glass layer with an outer surface decorative coating.
[18] The CdTe laminated photovoltaic glass layer 1 is a cadmium telluride thin film cell photovoltaic component in the composite board system. It has good weak-light power generation performance and thermal stability, is less affected by environmental factors, and is suitable for both exterior walls with strong light and shading.
[19] The negative temperature coefficient of photovoltaic modules is an important factor that influences their performance. In the building market, the commonly used single-crystalline silicon and polycrystalline silicon solar cells have a temperature response coefficient of -0.45 to -0.35. The temperature coefficient of amorphous silicon (cadmium telluride thin film) cells is lower than that of crystalline silicon cells, typically around -0.2. The testing standard for photovoltaic modules is based on a solar radiation of 1000 W/m2 and a cell temperature of °C, which is difficult to achieve in practical applications. The temperature of the photovoltaic module plate of the open support will generally reach 50-60°C under an external environment temperature of 25°C and good weather conditions with ground solar radiation intensity reaching 1000W/m2, resulting in a decrease in the output power of crystalline silicon photovoltaic modules to 10% to 13%. In the design of photovoltaic building wall, if the photovoltaic module is not well considered or installed improperly, the increase in the temperature of the photovoltaic module will cause a 15% to 18% decrease in the output power. The temperature coefficient of cadmium telluride thin-film cells is lower than that of crystalline silicon cells. Therefore, it can be directly combined with insulation materials to form a photovoltaic and thermal insulation composite panel. This composite panel will not be affected by poor ventilation and insufficient heat dissipation, which can cause a decrease in output power.
[20] Insulation layer 2 is sets at the outer side of the building wall, and the commonly used insulation material is fireproof rock wool board. Through factory processing, the cadmium telluride laminated photovoltaic glass 1 is bonded to the insulation layer 2 by using special adhesive 5. The cadmium telluride laminated photovoltaic glass 1, special adhesive 5, and insulation layer 2 are integrally formed, with strong adhesion and weather resistance.
[21] Cement-based backing layer 7 is attached to the inner side of the insulation layer 2 to protect the insulation layer 2. As the bottom layer of the composite board, it is fixed on the exterior wall by adhesive 6.
[22] After applying the mortar leveling layer 3 on the outer side of the building wall 4, the composite board is fixed on the building wall 4 by aluminium alloy fastener 8 and hot-dip galvanized angle steel 9.
[23] The hot-dip galvanized angle steel 9 is L-shaped, and one side of the hot-dip galvanized angle steel 9 is attached to the outer side of the mortar leveling layer 3. The other side of the hot-dip galvanized angle steel 9 is horizontally arranged. The side of the hot-dip galvanized angle steel 9 near the edge of the mortar leveling layer 3 is provided with a first mounting hole 901. An anchor 11 is provided in the first mounting hole 901, and the hot-dip galvanized angle steel 9 is connected to the building wall 4 through the anchor 11. The horizontal side of hot-dip galvanized Angle steel 9 is provided with a second mounting hole 902 and is bolted to the aluminum alloy fastener 8 through the second mounting hole 902.
[24] One end of the aluminium alloy fastener 8 is equipped with a third mounting hole 802, connecting to the second installation hole 902 on the hot-dip galvanized angle steel 9 through a connecting bolt 12. The other end of the aluminum alloy fastener 8 has mounting grooves 801 at both the top and bottom. The bottom groove is used to fix the lower photovoltaic glass 1, while the upper groove supports the upper photovoltaic glass 1, making the connection between adjacent glasses more stable.
[25] The thermal bridge blocking pad 10 is installed between the aluminium alloy fastener 8 and the hot-dip galvanized angle steel 9, with a thickness of 10-20mm. The thermal bridge blocking pad 10 is made of high-performance thermal insulation bridge material, polyurethane pouring adhesive. The thermal conductivity value of the polyurethane pouring adhesive is 0.12W/ (m K), which has good mechanical properties such as tensile strength, anti-fracture, and elongation, as well as high resistance to impact, wear, cutting, and fracture. It meets the requirements of high-performance thermal insulation bridges, as well as strength and durability, avoiding thermal bridging, improving the average heat transfer coefficient, and optimizing the overall thermal performance.
[26] As shown in Figures 5 to 8, the installation steps of the above-mentioned installation structure are:
S1, Locating the hot-dip galvanized angle steel 9 on the building wall 4 after the mortar leveling layer 3 constructed, and fix it to this position with anchor bolts 11.
S2, Using adhesive 6 to paste the composite board on the outside of the mortar leveling layer 3, and locate it under the hot-dip galvanized angle steel 9.
S3, Installing the aluminium alloy fastener 8, and using the installation groove 801 at the bottom of the aluminum alloy fastener 8 to clamp and fix the cadmium telluride laminated photovoltaic glass 1. Then, using connecting bolts 12 to connect the aluminum alloy clip 8 with the hot-dip galvanized angle steel 9 fixed on the building wall 4, and placing the high performance thermal bridge blocking pad 10 with a thickness of 10-20mm between the aluminum alloy clip 8 and the hot-dip galvanized angle steel 9.
S4, Fixing another composite board on the upper part of the aluminum alloy clip 8. Similarly, clamp the cadmium telluride laminated photovoltaic glass 1 in the installation groove 801 on the upper part of the aluminum alloy clip 8, and then use adhesive 6 to bond it to the outside of the mortar leveling layer 3 on the building wall 4. Repeat this process and install all the composite boards on the building wall 4 through the aluminum alloy clip 8 and the hot-dip galvanized angle steel 9.
[27] The present invention has the following effects:
1, The present invention utilizes cadmium telluride thin-film photovoltaic components, which exhibit excellent weak-light power generation performance and thermal stability and are less susceptible to environmental factors. These components are suitable for both exterior walls with strong light and shading conditions.
2, The cadmium telluride laminated photovoltaic glass and insulation material are directly connected and then installed to the building exterior wall. This invention does not need a large amount of fixed keel frames, which reduces the overall cost of the photovoltaic system, greatly simplifies the construction process, shortens the construction period, facilitates construction, and is beneficial to the application and promotion of solar photovoltaics.
3, This invention adopts the structure of adhesive bonding + hot-dip galvanized components fixing + high-performance thermal insulation material for cold bridge breaking. Such a process characteristic does not require a large amount of fixed keel frames or embedded parts connection, only the connection of some hot-dip galvanized components is needed. Furthermore, high-performance cold bridge blocking pads are added to reduce heat transfer cold bridges and improve the thermal insulation performance of the exterior wall.
