Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, and in particular to a flexible and transparent photovoltaic-energy storage integrated battery. Background Technology

[0002] Currently, solar energy, as a clean and renewable energy source, has received widespread attention and utilization in the energy sector. Solar photovoltaic cells can directly convert sunlight into electricity, but traditional solar photovoltaic systems have some limitations. On the one hand, most solar photovoltaic systems have a relatively simple structure, consisting only of solar panels. During the conversion of light energy into electricity, the panels themselves generate a large amount of heat, which is usually not effectively collected and utilized, but is directly dissipated into the environment, resulting in insufficient energy utilization and low overall energy conversion efficiency. On the other hand, solar energy is intermittent and significantly affected by factors such as weather and diurnal variations. The generated electricity cannot be supplied stably and continuously, requiring corresponding energy storage devices to store electrical energy to ensure stable energy output. However, existing energy storage batteries are often installed separately from solar cells, operating independently. This not only occupies a large space but may also result in losses during energy transmission, reducing the overall performance of the energy system. Furthermore, both solar cells and traditional energy storage batteries mostly lack flexibility and transparency, making it difficult to meet the needs of applications with special requirements for device appearance design, such as wearable electronic devices and transparent windows in smart buildings.

[0003] For example, Chinese utility model patent CN203896303U discloses a flexible energy storage device based on thin-film solar cells, including: a thin-film solar cell; at least one energy storage element disposed on the back surface of the thin-film solar cell; a housing element disposed on the surface of the thin-film solar cell and having a cavity inside; and a charging circuit disposed in the cavity inside the housing element, with its input end connected to the output end of the thin-film solar cell and its output end connected to the input end of the energy storage element. The charging circuit regulates and converts the DC power output by the thin-film solar cell to output DC power suitable for storage by the energy storage element.

[0004] This utility model presents a flexible energy storage device based on thin-film solar cells. It can be bent and deformed arbitrarily, making it suitable for various applications and environments. When not in use, it can be folded or rolled up for easy storage, offering advantages such as wide applicability and space saving. However, this solution still relies on a single method for collecting and converting solar energy, requiring long periods of sunlight and exhibiting low charging conversion efficiency and low solar energy utilization. Utility Model Content

[0005] To address the shortcomings in the aforementioned background technology, this utility model proposes a flexible and transparent integrated photovoltaic and energy storage battery, which solves the problem that existing solar energy storage batteries only convert solar energy in a single way and cannot convert it efficiently.

[0006] The technical solution of this utility model is implemented as follows: a flexible and transparent photovoltaic-storage integrated battery includes a thermoelectric battery, a solar thin-film battery and a flexible energy storage battery stacked together. The solar thin-film battery and the flexible energy storage battery are respectively attached to both sides of the thermoelectric battery, and the solar thin-film battery and the flexible energy storage battery are electrically connected to each other and the thermoelectric battery and the flexible energy storage battery.

[0007] Preferably, the solar thin-film battery, thermoelectric battery, and flexible energy storage battery are surrounded by a transparent encapsulation layer, which can effectively protect the internal structure of the battery from the influence of the external environment while maintaining overall transparency.

[0008] Preferably, the transparent encapsulation layer is a transparent epoxy resin film or a transparent silicone film.

[0009] Preferably, the flexible energy storage battery includes a flexible outer shell, an electrolyte filled inside the flexible outer shell, and a positive electrode and a secondary electrode fixedly disposed on the flexible outer shell. Both the positive electrode and the secondary electrode are L-shaped electrodes.

[0010] Preferably, the positive electrode and the secondary electrode are fixedly arranged in parallel with a gap between them, which facilitates full contact between the electrode and the electrolyte and improves the charging and discharging efficiency of the battery.

[0011] Preferably, the flexible outer shell is an epoxy resin film or a transparent silicone film, which provides good flexibility without affecting the transparency of the battery, meeting the appearance requirements of special application scenarios. The thermoelectric battery is a thermoelectric generator.

[0012] Preferably, the solar thin-film battery is a flexible and transparent perovskite solar cell or a polycrystalline silicon solar cell, which has high photoelectric conversion efficiency and good flexibility, and can adapt to deformations such as bending and folding, while ensuring the transmittance of sunlight.

[0013] Preferably, the solar thin-film battery and the flexible energy storage battery, as well as the thermoelectric battery and the flexible energy storage battery, are connected by wires or conductive adhesive to ensure the stability and reliability of the electrical connection.

[0014] The beneficial effects of this utility model are: 1. By stacking solar thin-film batteries, thermoelectric cells, and flexible energy storage batteries, the heat energy generated and absorbed by the solar thin-film batteries during power generation is collected by the thermoelectric cells and converted into electrical energy, which is then stored in the flexible energy storage batteries. This maximizes the utilization of solar energy, improves the energy conversion and utilization efficiency of the entire system, and reduces energy waste.

[0015] 2. The three parts are tightly stacked into a whole, which greatly saves space compared to traditional split solar power generation and energy storage devices. It is easy to install and use in environments with limited space, such as wearable devices and portable electronic devices, thus improving space utilization.

[0016] 3. Further: The overall use of flexible and transparent materials and design gives the photovoltaic-storage integrated battery good flexibility, allowing it to be bent and folded to adapt to curved surfaces of different shapes while maintaining transparency. This meets the appearance requirements of some special application scenarios, providing power without affecting light transmission, thus expanding its application range.

[0017] 4. Due to its high degree of integration, the number of parts and complex connection structures have been reduced, which has lowered production costs to a certain extent, while improving the overall performance and service life of the system, giving it good market competitiveness and application prospects.

When the battery is working, the solar thin-film battery 2 can receive sunlight to generate electrical energy and transmit it to the flexible energy storage battery for storage. While receiving sunlight to generate electrical energy, the solar thin-film battery absorbs heat energy and transfers it to the thermoelectric cell. The thermoelectric cell can generate thermoelectric potential using the temperature difference after sensing the heat energy, converting the heat energy into electrical energy and simultaneously transmitting it to the flexible energy storage battery for storage.

[0022] As a further specific embodiment, the solar thin-film battery 2, the thermoelectric battery 1, and the flexible energy storage battery 3 are surrounded by a transparent encapsulation layer.

Specifically, in this example, both the positive electrode 32 and the secondary electrode 33 are L-shaped electrodes. In this example, the short arms of the two L-shaped electrodes are arranged correspondingly, and the long arms are staggered. The long arms of the L-shaped electrodes protrude through the flexible outer shell, so that they can be connected to wires for discharging or charging.

[0025] Furthermore, the positive electrode 32 and the secondary electrode 33 are fixedly arranged in parallel with a gap between them. Specifically, in this embodiment, a 2mm gap is left between the short arm ends of the positive electrode 32 and the secondary electrode 33. The flexible shell 31 is a transparent epoxy resin film or a transparent silicone film, satisfying the requirements of flexibility and transparency.

[0026] As a specific optional implementation, in this embodiment, the outer shell is a transparent epoxy resin film layer with a thickness of approximately 0.5 mm, possessing good flexibility, transparency, and insulation properties. The interior is filled with a gel electrolyte, made from the organic solvent propylene carbonate and the lithium salt lithium hexafluorophosphate, exhibiting high ionic conductivity to ensure smooth lithium ion migration.

[0027] In addition, the thermoelectric battery 1 is a thermoelectric generator. Specifically, in this embodiment, an SP1848-27145 type thermoelectric generator is used, which can generate electrical energy by utilizing temperature difference and store it in a flexible energy storage battery.

[0028] In practical applications, the photovoltaic-energy storage integrated battery of this invention can be widely used in smart wearable devices, IoT sensor nodes, smart home systems, and small mobile electronic devices. For example, in smart wearable devices, it can be used as the strap of smartwatches and smart bracelets, meeting the requirements of flexible and transparent design while providing a stable energy supply; in IoT sensor nodes, it can serve as a self-powered power source, improving the sensor's battery life and environmental adaptability; in smart home systems, it can be applied to smart windows and smart curtains, achieving energy self-sufficiency and reducing energy consumption; in small mobile electronic devices, it can temporarily utilize solar energy for charging and energy storage in outdoor scenarios, improving the device's portability and practicality, and providing an efficient and integrated solution for the application of new energy technologies in various fields.
