In the present embodiment, the solar wafers 120 are arranged in a plurality of wafer strings 120a, wherein a plurality of strips spaced apart from each other and opaque are formed in the solar wafer module 102 due to the opaque nature of the solar wafers 120 themselves. The first region R1 is shaped, and at the same time, a plurality of strip-shaped second regions R2 which are alternately arranged with the first region R1 without being shielded by the solar wafer 120 are formed. In detail, the transparent carrier 110 of the solar wafer module 102 has a first region R1 and a second region R2. The solar wafer 120 is disposed in the first region R1 of the transparent carrier 110 and located in the second region R2. Further, the second region R2 is kept in a light transmitting state. Thereby, the solar wafer 120 of the first region R1 can receive sunlight for photoelectric conversion, and the heat collecting fins 106 located in the first region R1 can collect waste heat for operation of the solar wafer 120 for heating the working fluid.

Generally, a metal having good thermal conductivity such as copper, aluminum, stainless steel or steel may be selected.

On the other hand, in order to prevent thermal energy from accumulating around the junction between the second heat collecting fin tube 160 and the light transmissive carrier 110 of the solar wafer module 102 (shown in FIG. 3), it cannot be effectively transmitted to the second heat collecting fin. The working fluid in the tube 160, in this embodiment, separates the plurality of second heat collecting fin tubes 160 from the light transmissive carrier plate 110 (shown in FIG. 3) of the solar wafer module 102 by an air gap g. In an embodiment, the air gap g is greater than or equal to 3 mm. More specifically, each of the second heat collecting fins 160 includes a second fin 162 and a second tube 164, wherein the second fin 162 and the light transmissive carrier 110 of the solar wafer module 102 (see FIG. 3) Shown) separated by air gap g. The second fin 162 has a first surface 160a facing the transparent carrier 110 and a second surface 160b opposite to the first surface 162a. The second tube 164 is coupled to the second surface 160b of the second fin 162. Since the second fin 162 is separated from the light-transmissive carrier 110 of the solar chip module 102 (shown in FIG. 3 ) by an air gap g, the aforementioned heat energy accumulation problem can be avoided, and the heat energy loss can be prevented. And greatly improve solar energy utilization.

In addition, in this embodiment, a selective absorption layer 180 is disposed on the first surface 160a of the second fin 162, and the selective absorption layer 180 covers the first surface 160a of the second fin 162, thereby improving the second fin. 162 is the heat absorption efficiency relative to sunlight. Here, the selective absorption layer 180 is a multilayer structure in which the material may include a nickel oxide compound (such as a multilayer stack of Ni-NiOx/Cu-Ni/Al), a chromium oxide compound (such as CrN). -Multilayer stacking method of CrxOy/Cu), titanium oxynitride compound (such as multi-layer stacking method of TiNxOy/Cu), chromium carbide compound (such as multi-layer stacking method of Cu-Cr-C/Cu), graphite, cerium oxide or naphthalene Rice toner, etc., or other materials with the same or similar photothermal conversion effects. The photothermal conversion efficiency of the selective absorption layer 180 selected in this embodiment may be greater than 85%. In addition, the second fin 162 may be metal, and generally a metal having good thermal conductivity such as copper, aluminum, stainless steel or steel may be selected.

In order to collect the light passing through the second region R2 as much as possible, the area of the second fin 162 and the selective absorption layer 180 of the embodiment may be greater than or equal to the area of the second region R2, or as shown in FIG. The width W1 of the second fin 162 may be greater than or equal to the width W2 of the second region R2.

In addition, in the accommodating space formed by the solar wafer module 102 and the housing 104, an insulation/insulation material such as foamed cotton, fiberglass cotton, or the like may be filled to avoid the first fin tube 150 and the second fin tube. The heat energy in 160 is dissipated, which further enhances the effect of heat storage.

In summary, the solar wafer module of the power generation heat storage device of the present disclosure is respectively provided with a first region of the solar wafer and a second region not provided with the solar wafer. The solar wafer of the first zone can receive sunlight for photoelectric conversion, and the first heat collecting fin of the first zone is attached to the transparent carrier to collect waste heat for operation of the solar wafer for heating the working fluid. . In addition, the second region of the solar wafer module is not provided with a solar wafer, so sunlight can pass through the second region of the solar wafer module to reach the second heat collecting fin. The second set of fins collects the heat of the sunlight to heat the working fluid. Since the first heat collecting fin of the first zone is attached to the light-transmitting carrier, the residual heat outside the operation of the solar wafer can be efficiently conducted to the first heat collecting fin. Moreover, since the second heat collecting fin tube of the second region is separated from the light transmitting carrier by an air gap, heat energy can be prevented from being accumulated around the junction surface of the second heat collecting fin tube and the light transmitting carrier plate, and cannot be effectively transmitted to the second surface. Collect the working fluid inside the fin tube to prevent the loss of thermal energy. Thereby, the power generation and heat storage device disclosed in the present invention can effectively integrate the solar photovoltaic generator system and the solar heat storage mechanism, not only can simultaneously generate and store heat energy, but also greatly improve the solar energy utilization rate per unit area.
