In the field of traditional solar power generation, the crystalline silicon solar cell has high manufacturing cost, low photoelectric conversion efficiency, high input cost and low return, and can obtain benefits after being applied in a large area after being operated for many years. In recent years, once the perovskite solar cell is developed, the upper limit of the photoelectric conversion efficiency is continuously broken through in more than ten years, the upper limit of the photoelectric conversion efficiency exceeds the limit of the photoelectric conversion efficiency of the existing crystalline silicon technology, and the perovskite solar cell has the advantages of lower cost, higher efficiency and more applications. However, the stability of the perovskite solar cell makes it difficult to put it into practical use, wherein the working conditions of temperature and humidity have the greatest influence on the operating life of the perovskite, and unhealthy conditions of temperature and humidity will reduce the power generation efficiency of the perovskite solar cell, and degrade the perovskite layer, and most of the cells are connected in series, so that the output current is too small to meet the actual requirements.

Referring to fig. 1 to 5, the present invention provides a photovoltaic thermoelectric coupling flexible power generation apparatus, which may include: the flexible composite phase change material energy storage layer comprises a quadrangular frustum pyramid with an upper bottom surface larger than a lower bottom surface and a protruding platform connected to the lower bottom surface of the quadrangular frustum pyramid; the hot face of each thermoelectric generation flexible thin film battery is thermally connected with the protruding platform, wherein the flexible composite phase change material energy storage layer absorbs the heat generated by the perovskite solar thin film battery 1 on the upper layer during the daytime due to light irradiation, so that the working temperature of the perovskite solar thin film battery 1 is kept in a set interval, and meanwhile, the absorbed heat during the daytime is transmitted to the thermoelectric generation flexible thin film battery attached to the bottom layer all day long, so that thermoelectric generation is carried out. In this embodiment, the perovskite solar thin film cell 1 collects light in the daytime to complete power generation.
Therefore, the energy storage layer made of the flexible composite phase change material can absorb heat generated by solar radiation of the perovskite solar thin film cell 1, so that the temperature interval of the perovskite solar thin film cell 1 is always in the state that the output power is optimal, the effective temperature control of the perovskite solar thin film cell 1 is realized, the photovoltaic power generation efficiency of the perovskite solar thin film cell 1 is improved, and the stable and long-term operation of the perovskite solar thin film cell is guaranteed. In addition, through carrying out thermoelectric generation at night with the heat that will store in flexible composite phase change material energy storage layer, can compensate the shortcoming that photovoltaic cell can't generate electricity at night, simultaneously through coupling solar cell and the flexible thin film battery of thermoelectric generation, through the parallel circuit between the battery, can improve output current, solve the problem of traditional series connection battery output current undersize.
Referring again to fig. 1, 2 and 4, the photovoltaic thermoelectric coupling flexible power generation device of the present invention may include: the device comprises a perovskite solar thin film battery 1, a flexible composite phase change material energy storage layer, a thermoelectric generation flexible thin film battery and an outer packaging shell layer.
The perovskite solar thin film cell 1 may be exemplified by a mesoporous perovskite type solar cell and a planar perovskite type solar cell, which may be generally classified into a five-layer structure, an Electron Transport Layer (ETL), an activated perovskite layer, an HTL, an electrode, and a substrate, respectively. The active perovskite layer is a light absorption layer and plays a role in absorbing incident light and transferring charges generated under illumination, the ETL layer and the HTL layer respectively transmit electrons and holes, and the electrons and the holes are led out from the electrodes to form a communication circuit so as to generate current.
Exemplarily, the whole flexible composite phase-change material energy storage layer can adopt a square funnel shape, and can be divided into a flexible composite phase-change material energy storage layer top 2 and a flexible composite phase-change material energy storage layer bottom 3, wherein the flexible composite phase-change material energy storage layer top 2 is attached to the perovskite solar thin film battery 1, can absorb heat generated in the photovoltaic power generation process, and is stored and transmitted to the flexible composite phase-change material energy storage layer bottom 3. The side of the bottom 3 of the flexible composite phase-change material energy storage layer is respectively attached to the conductive blocks 4 in the thermoelectric power generation flexible thin-film battery, and stored heat can be transmitted to the conductive blocks 4. The flexible composite phase change material energy storage layer can play a role in absorbing heat generated in the power generation process of the solar cell, so that the temperature of the device is effectively controlled, the perovskite solar thin film cell 1 is kept at the temperature for realizing high-efficiency power generation, and meanwhile, the flexible composite phase change material energy storage layer is used as a heat conduction element between the perovskite solar thin film cell 1 and the thermoelectric generation flexible thin film cell. In addition, the flexible composite phase change material energy storage layer can be bent and has certain ductility, the flexibility of the whole battery device can be reserved, and the applicability of the device is enhanced.
Specifically, the flexible composite phase change material energy storage layer plays a role all day long, absorbs heat generated by the perovskite solar thin film cell 1 on the upper layer due to light irradiation in the daytime, has huge phase change latent heat, and can keep the working temperature of the perovskite solar thin film cell 1 in a proper range, so that the photovoltaic power generation efficiency is improved, and the service life of the perovskite solar thin film cell is prolonged; the heat absorbed in the daytime is transmitted to the conductive block 4 attached to the bottom layer all day (including night), the temperature of the hot surface of the thermoelectric film 5 is increased, and a large temperature difference is formed between the hot surface of the thermoelectric film 5 and the cold surface of the thermoelectric film 5, so that thermoelectric power generation is performed.
Referring to fig. 3, the thermoelectric generation flexible thin film battery may include a thermoelectric thin film 5, a substrate 6, and a conductive block 4. The conductive block 4 is divided into an inner periphery and an outer periphery, wherein the inner periphery conductive block is used as a conductive and heat-conducting element with a hot end connected with a p-n junction, and the outer periphery conductive block is used as a conductive and heat-conducting element connected with different pairs of p-n junctions in series. The thermoelectric thin film 5 having a non-constant cross section along the heat conduction direction is used as the thermoelectric thin film 5, and the effective seebeck coefficient is enhanced as compared with a symmetric thermoelectric element because: on one hand, the integral heat conductivity is reduced, and the temperature difference of the cold end and the hot end of the thermoelectric film is increased; on the other hand, the Thomson effect is utilized, and the enhanced effective Seebeck coefficient can be obtained by combining the Thomson effect and the inherent Seebeck coefficient of the thermoelectric element.
Specifically, the working principle of the thermoelectric generation flexible thin film battery is as follows: the temperature of the inner peripheral conducting block is increased due to the fact that the temperature of the heat of the flexible composite phase-change material energy storage layer is received, the temperature of the peripheral conducting block is close to the ambient temperature, and the cold end and the hot end of the thermoelectric film 5 form large temperature difference. Under the temperature gradient, the carriers in the thermoelectric thin film 5 diffuse to the low temperature direction, and the seebeck voltage is formed at the two ends, so that the communication circuit can generate electricity.
Referring to fig. 5, in some embodiments, a parallel circuit connection is used between the thermoelectric generation flexible thin film cell and the perovskite solar thin film cell 1. Specifically, on one hand, the parallel connection mode is adopted, so that the realization of the lamination mechanism is facilitated; on the other hand, the positive electrode and the positive electrode or the negative electrode and the negative electrode of the two batteries can be connected through soldering tin, so that the stability of the structure is ensured, the circuit is simplified, and higher output current can be obtained.
In some embodiments, the flexible composite phase change material energy storage layer is of a square funnel shape, and the shape and the size of the cross section of the top of the flexible composite phase change material energy storage layer are the same as those of the perovskite solar thin film cell 1; the cross section shape of the bottom is adjusted along with the number of pairs of p-n junctions of the thermoelectric film 5, four pairs of p-n junctions can be set, namely a square is adopted, the side length of the square is slightly larger than the long side of the hot-face conducting block, and is about 1.1 times of the long side of the conducting block 4.
Specifically, the thermoelectric generation flexible thin film battery comprises four pairs of p-n junctions, and the conducting blocks 4 on the hot surfaces of each pair of p-n junctions are respectively attached to the bottom 3 of the flexible composite phase change material energy storage layer so as to receive heat and improve the temperature of the hot surfaces. Due to the low heat conductivity coefficient of the thermoelectric film 5, the temperature of the cold surface is similar to that of the external environment, and the cold surface and the hot surface form a large temperature difference to generate Seebeck voltage. Meanwhile, 4 pairs of p-n junctions contained in the thermoelectric generation flexible thin film battery are connected in series. The cross section of the thermoelectric thin film 5 prepared by the thermoelectric power generation flexible thin film battery along the flow guiding direction is a variable cross section. Preferably, a plurality of pairs of p-n junctions can be added to improve the generating voltage of the thermoelectric generation flexible thin film battery. When a plurality of pairs of p-n junctions are added, the array mode of all the p-n junctions needs to be adjusted and modified so as to meet the requirement of maximum space utilization under the limited area.
In some embodiments, the shape of the present power generation device may be either of a cube or a cylinder. For example, if the overall device is a cube, the maximum cross-section of the three internal components would be square; if the whole device is a cylinder, the maximum cross section of the three internal components should be circular to ensure good packaging effect.
In conclusion, the flexible thin film thermoelectric power generation device and the flexible composite phase change material are adopted, the application characteristics of the flexible thin film perovskite solar cell can be adhered, a new structure is designed for packaging, the effective temperature control of the perovskite solar cell can be realized, the flexibility characteristics of the whole device are kept, the photovoltaic power generation efficiency is improved, the service life is prolonged, the heat storage is carried out by utilizing the phase change material in the daytime, the thermoelectric power generation is carried out at night to make up the defect that the photovoltaic cell cannot generate power at night, meanwhile, the structure is simpler and more convenient, and the output current is larger, the invention provides a new parallel circuit connection mode, and the problem that the output current of the traditional series battery is too small is solved.
