Description

Solar fan cap

This creation is about a solar fan cap, especially a solar fan cap that converts solar energy into electrical energy to give people comfort and ease of use and low cost.

In the hot summer, people usually go out with a sun hat to prevent the sun from burning on the facial skin. In winter, people will wear a hat lower than the winter cold. However, in addition to the effect of keeping warm or shading, the existing hats have no other functions, especially in the summer. In addition to blocking strong light, the sun hat can not alleviate the heat brought by the hot sun, nor can it bring people a cool feeling.

Accordingly, it is an object of the present invention to provide a solar fan cap that converts solar energy into electrical energy to provide comfort and ease of use and low cost.

Therefore, the present invention includes a cap, a solar power module and a fan disposed on the cap, and a circuit between the solar power module and the fan is further connected with a DC-DC converter and a switch, the solar power module The solar panel, the battery, the upper cover, the lower cover and the circuit board are located in a space surrounded by the upper cover and the lower cover, and the solar panel and the circuit board are electrically connected to the battery.

The solar fan cap provided by the creation can convert the electric energy provided by the solar power module into a stable voltage to supply the fan, and the solar cap can be used to cool the user in the summer, and the solar energy can be converted into electric energy by the utility model. Working through the fan It gives people a more comfortable feeling, no need to change and charge the battery repeatedly, easy to use and low cost, and the battery life is strong, especially when it is outdoors or watching events.

Figure 1 is a schematic view of the structure of the novel embodiment.

Figure 2 is a schematic view of the structure of a solar panel.

Referring to FIG. 1 and FIG. 2 , the present invention provides a solar fan cap including a cap 1 , a solar power module 2 disposed on the cap 1 , and a fan 5 , between the solar power module 2 and the fan 5 . The DC-DC converter 4 and the switch 3 are also connected in turn in the circuit.

The solar power module 2 includes a solar panel 21, a battery 22, an upper cover 23, a lower cover 24, and a circuit board 25. The circuit board 25 is located in a space surrounded by the upper cover 23 and the lower cover 24. The solar panel 21 The circuit board 25 is electrically connected to the battery 22, and the outer cover 23 and the lower cover 24 are respectively provided with a decorative plate 26 on the outer side.

The solar panel 21 may be a copper indium gallium selenide thin film solar panel, a single junction amorphous germanium thin film solar panel, a double junction amorphous germanium thin film solar panel, a single crystal germanium solar panel, or a polycrystalline germanium solar panel.

The copper indium gallium selenide thin film solar cell panel comprises a substrate on which a first molybdenum layer, a second molybdenum layer, a copper indium gallium selenide layer, a cadmium sulfide layer, an intrinsic zinc oxide layer, and an aluminum doped layer are sequentially deposited. An intrinsic zinc oxide film layer, a magnesium fluoride layer, a nickel film and an aluminum layer, the first molybdenum layer being a transition layer, the molybdenum layer having good adhesion to the soda lime glass substrate, and the second molybdenum layer as a back electrode In order to reduce the resistance of the backing layer to facilitate the formation of a good ohmic contact of the subsequent absorber layer, the copper indium gallium selenide The gold layer is made of an alloy material of copper, indium, gallium and selenium, thereby forming a P-type portion in the PN junction of the copper indium gallium selenide thin film solar cell, and the cadmium sulfide layer is a buffer layer which is copper indium gallium selenide. The N-type portion of the PN junction of the thin film solar cell may be replaced by a zinc sulfide layer, and the aluminum-doped essential zinc oxide film layer on the upper portion of the essential zinc oxide layer is a window layer to increase the thickness of the thin film solar cell. Light transmittance, the magnesium fluoride layer is an anti-reflection layer of a copper indium gallium selenide thin film solar cell, and an aluminum layer upper electrode on the nickel film. The substrate of the copper indium gallium selenide thin film solar panel can be glass, stainless steel, plastic, Polyimide polyimide and PET polyethylene terephthalate, etc., the copper indium gallium selenide thin film solar cell of the utility model The plate is made of a nano-calcium glass substrate.

The single junction amorphous germanium thin film solar cell sheet comprises an amorphous germanium substrate on which a transparent conductive film (TCO) is first deposited, and then a p layer (generally amorphous tantalum carbide alloy a) is sequentially deposited on the transparent conductive film. - SiC: H), i layer (essential layer), n layer and back electrode (generally aluminum or silver).

The double-junction non-thin film solar cell panel comprises an amorphous germanium substrate on which a transparent conductive film (TCO) is first deposited, and then a p-layer (generally amorphous tantalum carbide alloy a) is sequentially deposited on the transparent conductive film. - SiC: H), i layer (essential layer), n layer, p layer (generally amorphous niobium carbide a-SiC: H), i layer (essential layer), n layer and back electrode (generally aluminum or silver).

The single crystal solar panel and the multi-body solar panel remove shallow damage, oxidation, grooving, cleaning, and second time on the entire surface of the crucible after removing the damaged layer and the texturing on the substrate of the single crystal germanium or the polycrystalline crucible. Diffusion and metallization of the battery.

Working principle: the solar power module 2 converts solar energy into electric energy and stores it in the battery 22, and the DC-DC converter 4 can convert the electric energy provided by the solar power module 2 into a stable voltage to supply the fan 5 to work. The fan 5 can be turned on or off by the switch 3, The use of the solar cap in the summer can make the user more cool. The battery 22 can continuously provide a stable voltage to the fan, and the utility model can convert solar energy into electric energy and bring more comfortable to the people through the work of the fan 5. feel.
