Embodiment
Below with reference to the drawings, the present invention is described in further detail.
Refer to Fig. 1, embodiment of the present invention device of solar generating 100 comprises shell 10, piezoelectric material layer 20, metal material layer 30, heat carrier 40, piezoelectric thin film layer 50 and an actuator 60.
Described shell 10 comprises the lower cover 103 that sidewall 102, that a upper cover be made up of solar heat-collection plate 101, is made up of heat insulator is made up of heat dissipation element.Described upper cover 101 is positioned at the top of device of solar generating 100, and it is vacuum heat collection pipe composition, effectively can absorb the thermal radiation that sunlight produces, and have the feature of resistance to air drying, not easily booster.Described sidewall 102 is positioned at the side of device of solar generating 100, and it is ceramic fibre material, can effectively reduce heat radiation and go out, and has low heat conduction, resistant to elevated temperatures character.Described lower cover 103 is positioned at the bottom of device of solar generating 100, and it is heat pipe, can be gone out by the heat conduction of the element be in contact with it rapidly.
Described piezoelectric material layer 20 is fixed on the inner surface of sidewall 102, and it is nano zine oxide.Described metal material layer 30 is formed at piezoelectric material layer 20 and is close on the inner surface at device of solar generating 100 center, and metal material layer 30 adopts the precious metal material such as gold, silver, platinum to be formed.This piezoelectric material layer 20 forms a Schottky contacts, in order to the surface making the electronic energy in piezoelectric material layer 20 be gathered in metal material layer 30 with the interface of metal material layer 30.Time so-called Schottky contacts refers to that metal and semi-conducting material contact, at the band curvature of interface semiconductor, form Schottky barrier.
Described heat carrier 40 is positioned at immediately below upper cover, and in order to conduct the solar heat that upper cover 101 is collected, its side is relative with metal material layer 30.This heat carrier 40 also moves up and down in the space that can form at shell 10.One protruding 402 and one side 403 contacted with metal material layer 30 that this heat carrier 40 comprises a surface 401 relative with the upper surface of lower cover 103, vertically extends from this surface 401, described protruding 402 for device of solar generating operationally, inconsistent with lower cover 103, heat conduction unnecessary on heat carrier 40 is gone out.Described heat carrier 40 is metal heat-conducting material, and its heat conduction that can be effectively collected by upper cover 101 gives other elements, and heat carrier 40 can produce certain expansion under heating condition.
Described piezoelectric thin film layer 50 is formed on heat carrier 40 side relative with metal material layer 30, after expanded by heating, interference fit is formed between this piezoelectric thin film layer 50 and metal material layer 30, and when actuator 60 moves, actuator 60 can drive piezoelectric thin film layer 50 and metal material layer 30 relative motion.Described piezoelectric thin film layer 50 is the piezoelectric such as nano zine oxide, lead zirconate titanate.
Described actuator 60 is fixed between the upper surface of lower cover 103 and heat carrier 40 surface 401, and it is made up of flexible member 602 and memorial alloy body 601.When upper cover 101 does not receive illumination, the length of flexible member 602 is less than its natural length, is namely in compressive state and its pressure being greater than heat carrier 40 pairs of flexible members 602 to elastic force produced, makes the upper surface of heat carrier 40 contact at upper cover 101; And the length of memorial alloy body 601 is greater than its initial length, be namely in extended state.When memorial alloy body 601 reaches its deformation temperature, initial length will be contracted to.
Refer to Fig. 2 and Fig. 3, during work, under initially not receiving illumination conditions, because flexible member 602 elastic force is upwards greater than the pressure of heat carrier 40 pairs of flexible members 602, then make the upper surface of heat carrier 40 contact at upper cover 101.And now, the length of memorial alloy body 601 is greater than its initial length, and be in extended state.When upper cover 101 receives solar light irradiation, produce certain heat, heat carrier 40 expanded by heating, and by heat conduction to memorial alloy body 601, when suffered by memorial alloy body 601, temperature exceedes its deformation temperature, memorial alloy body 601 owing to will return to its initial length, then produces a downward pulling force.When the downward pressure of heat carrier 40 and the downward pulling force of memorial alloy body 601 are greater than flexible member 602 elastic force upwards and the frictional force between piezoelectric thin film layer 50 and metal material layer 30, heat carrier 40 moves downward, until the projection 402 on heat carrier 40 contacts with lower cover 103.Now, because the heat-sinking capability that lower cover 103 is stronger for heat pipe has, temperature on heat carrier 40 and memorial alloy body 601 can decline in the short period of time, heat carrier 40 shrinks, now, being formed between piezoelectric thin film layer 50 on heat carrier 40 and metal material layer 30 is non-interference mated condition, and when the temperature on memorial alloy body 601 is less than its deformation temperature, memorial alloy body 601 is not because need return to its initial length and lose downward pulling force.And now, because the pressure that heat carrier 40 is downward is less than flexible member 602 elastic force upwards, heat carrier 40 moves upward, until against the lower surface of upper cover 101.When the temperature on memorial alloy body 601 reaches its deformation temperature again, repeat above-mentioned action.Constantly move up and down due to heat carrier 40 and expand with heat and contract with cold, and piezoelectric thin film layer 50 and metal material layer 30 are interference fit after expanded by heating, be formed at the transverse shear stress between the metal material layer 30 on piezoelectric material layer 20 surface and the piezoelectric thin film layer 50 being formed at heat carrier 40 surface, piezoelectric material layer 20 and piezoelectric thin film layer 50 is made to produce certain deformation, because piezoelectric effect produces an electric field; Under the effect of electric field, the electric charge being positioned at Schottky surface is derived, and forms electric current.And by use of being connected by multiple device of solar generating 100, the heat that lower cover 103 conducts is supplied to next device of solar generating 100 and uses, the heat making sunlight produce can effectively utilize.By being connected a wire 301 and 501 at metal material layer 30 with piezoelectric thin film layer 50 surface respectively, the movement of electric charge under the effect of electric field on metal material layer 30 surface, in wire 301 and 501, form electric current, wire 301 with 501 the other end can be connected a power storage devices or load.
The converting heat of the sunlight collected can will be able to be electric energy by device of solar generating of the present invention, and is not subject to the impact of position and weather condition, improves the convenience of use, and can not produce any pollution.Relative to solar cell, significantly can reduce cost of manufacture, and conversion efficiency effectively can promote.
In addition, those skilled in the art also can do other change in spirit of the present invention, and certainly, these changes done according to the present invention's spirit, all should be included within the present invention's scope required for protection.
