[Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1, a solar power generation device 100 according to an embodiment of the present invention includes a casing 10, a piezoelectric material layer 20, a metal material layer 30, a heat conductor 40, a piezoelectric film layer 50, and an actuator 60. The outer casing 10 includes an upper cover 101 composed of a solar heat collecting plate, a side wall 102 composed of a heat insulating material, and a lower cover 103 composed of a heat dissipating member. The upper cover 101 is located at the top of the solar power generation device 100, and is composed of a vacuum heat collecting tube, which can effectively absorb the heat radiation generated by sunlight, and has the characteristics of being resistant to air drying and not blasting. The side wall 1〇2 is located on the side of the solar power generating device 100, which is a Tauman fiber material, which can effectively reduce heat radiation and has low heat conduction and high temperature resistance. The lower cover 103 is located at the bottom end of the solar power unit 1 , which is a heat pipe, and can quickly conduct heat of the components in contact therewith. The piezoelectric material layer 20 is fixed to the inner surface of the side wall 102, which is nano zinc oxide. The metal material layer 30 is formed on the inner surface of the piezoelectric material layer 2'' near the center of the solar power generation device 100, and the metal material layer 3' is formed of a noble metal material such as gold, silver or platinum. The piezoelectric material layer 2 is in contact with the interface of the metal material layer 30 to form a Schottky contact for collecting electrons in the piezoelectric material layer 20 on the surface of the metal material layer 30. The so-called Schottmei contact means that when the metal and the semiconductor material are in contact, the band of the semiconductor at the interface is bent to form a Schottky barrier.

The protrusion 4〇2 is used for the solar power generation device to contact the lower cover 103 during operation, and the excess heat on the heat conductor 40 is conducted out. The heat conductor 40 is a metal heat conductive material, which can effectively The heat collected by the upper cover 1〇1 is transmitted to other components, and the thermal conductor 40 is expanded under heat. The piezoelectric film layer 50 is formed on the thermal conductor 40 and the metal material layer 3〇8 200952317. The surface of the piezoelectric film layer 50 and the metal material layer 30 form an interference fit after the thermal expansion of the fork, and when the actuator 60 moves, the actuator 60 can drive the piezoelectric film layer 5 and the metal material layer. 3〇 relative motion. The piezoelectric film layer 50 is nano zinc oxide A piezoelectric material such as lead zirconate titanate. The actuator 60 is fixed between the upper surface of the lower cover 1〇3 and the surface 401 of the thermal conductor 4, and is composed of an elastic member 6〇2 and a memory alloy body 6〇1. When the upper cover 101 does not receive the illumination, the length of the elastic member 6〇2 is less than 0, its natural length, that is, in a compressed state and the resulting elastic force is greater than the pressure of the thermal conductive body 40 against the elastic member 602, so that the thermal conductor 4〇 The upper surface is in contact with the upper cover 101; and the length of the memory alloy body 601 is greater than its initial length, that is, in a stretched state. When the memory alloy body 601 reaches its deformation temperature, it shrinks to the initial length. See Fig. 2 and Fig. 3. When working, in the initial state of no illumination, since the elastic force of the elastic member 6〇2 is greater than the pressure of the thermal conductor 4〇 against the elastic member 602, the upper surface of the thermal conductor 4〇 is in contact with the upper cover ❹ 1〇 1. At this time, the length of the memory alloy body 601 is greater than the initial length, and is in a stretched state. When the upper cover 101 receives sunlight, a heat is generated, and the heat conductor 4 is thermally expanded and conducts heat to the heat. memory When the temperature of the memory alloy body 601 exceeds its deformation temperature, the memory alloy body 601 generates a downward force due to its return to its original length. When the heat conductor 4, the downward pressure and the memory alloy body 601 When the downward pulling force is greater than the upward elastic force of the elastic 7G member 602 and the friction between the piezoelectric film layer 5 and the metal material layer 30, the heat conductor 4〇 moves downward until the protrusion 402 and the lower cover on the heat conductor 40 103 contact. At this time, because the lower cover 1〇3 9 200952317 has a strong heat dissipation capability for the heat pipe, the temperature on the heat conductor 40 and the memory alloy body 601 can be lowered in a short period of time, and the heat conductor 4 shrinks. At this time, between the piezoelectric thin layer 5〇 formed on the heat conductor 40 and the metal material layer 3〇

At this time, since the downward pressure of the heat conductor 4 is smaller than the spring force of the spring 602, the heat conductor 4 is. Move up until it reaches the lower surface of the upper cover. When the temperature on the memory alloy body 6〇1 reaches its deformation temperature again, the coating is repeated. The thermal conductor 4() is continuously heated and contracted, and the piezoelectric film layer 5〇 and the metal material layer 3 are subjected to an interference fit after thermal expansion, and the metal formed on the surface of the piezoelectric material layer 2 = transverse extrusion between the material layer 30 and the piezoelectric film layer 5〇 formed on the surface of the heat conductor 4, causing a certain deformation of the piezoelectric material layer 2〇 and the piezoelectric film layer 5〇, due to the piezoelectric effect An electric field; under the action of an electric field, the charge on the surface of the Schottky is derived to form a current. Further, by using a plurality of solar power generation devices 1 in series, the heat conducted by the lower cover 1〇3 is supplied to the next solar power generation device 100, and the heat generated by the sunlight is effectively utilized. By connecting a wire 3〇1 and 5〇1 to the surface of the metal material layer 3〇 and the piezoelectric film layer 50, respectively, the charge of the surface of the metal material layer 3 is moved by the electric field, and the wires 301 and 501 The formation of the electric muscle 'can be connected at the other end of the wires 3G1 and 501 - the power storage device or the load. The solar power generating device of the present invention can convert the heat of the collected sunlight into electric energy, and is less susceptible to the influence of the position and weather conditions, thereby improving the convenience of use without any pollution. Compared with solar cells, 200952317 can significantly reduce production costs, and conversion efficiency can be effectively improved.
