Hereinafter, a solar power generation greenhouse utilizing a solar cell according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a solar power generation greenhouse using a solar cell according to an embodiment of the present invention, and FIG. 2 is a sectional view showing a solar power generation greenhouse using the solar cell shown in FIG.

As shown in FIGS. 1 and 2, a solar power generating greenhouse using a solar cell according to an embodiment of the present invention is formed by combining a plurality of inclined surfaces to form a roof 140, A greenhouse 100 which is enclosed with a double glass 120 for cultivation and a dye which is provided between the double glass 120 and surrounds an outer wall of the greenhouse 100 to absorb and transmit sunlight, A solar cell module 300 provided on one side of the roof 140 into which direct sunlight flows and absorbing sunlight to produce electricity; And a power storage system (400) for storing electric energy generated from the solar module (300).

The greenhouse 100 is a structure for cultivating various plants by controlling light rays, temperature, humidity, and the like, and the temperature inside the greenhouse 100 can be controlled according to the growing method of plants. The greenhouse 100 is supplied with sunlight, and solar power can be generated from the roof 140, especially the outer wall, so as to minimize a blind spot caused by shadows or other obstacles.

The greenhouse 100 includes a frame 110 for forming the outer wall and the roof 140 and a double glass 110 for enclosing the frame 110 and for transmitting sunlight to the inside of the greenhouse 100. [ (130) installed in the greenhouse (100) to compensate for insufficient wavelengths of the sunny plants or to control nighttime growth, and a second solar cell 200), and a light diffusion film (120) installed in the interior of the roof (140) to diffuse solar light transmitted without being absorbed by the first solar cell (200) Shielding film 500 for shielding sunlight flowing into the greenhouse 100 through an achromatic third solar cell 210 installed on the other surface of the outer wall on which the light diffusion film 150 is installed, ).

The frame 110 may be assembled and installed in various shapes on the ground so that the shape of the greenhouse 100 may be variously formed. The frame 110 may be formed of various materials such as steel or aluminum to support the load of the greenhouse 100.

The shape of the outer wall and the roof 140 is determined by the frame 110 and the first solar cell 200 and the solar module 300 that surround the outside of the greenhouse 100 may be installed.

The double glass 120 may be installed between the frames 110 and the outside so that the first solar cell 200 and the solar module 300 can be accommodated therein. Temperature and humidity of the inside of the apparatus 100 are maintained and the heat bridging phenomenon with the outside can be blocked.

The illumination device 130 is a device for adjusting the irradiation amount of the LED by supplying electric energy to a plurality of LEDs installed in the greenhouse 100. The illumination device 130 is a device The dose can be increased or decreased. In addition, when LEDs of various wavelengths are mounted in the greenhouse 100, electricity can be supplied only to LEDs of a desired wavelength, if necessary, so that light of a wavelength necessary for plants in the greenhouse 100 can be supplied.

Thus, the lighting device 130 supplies electric energy stored in the power storage system 400 to the lighting device 130. That is, after determining whether or not the amount of solar radiation is insufficient, the insufficient amount of solar radiation can be supplied by supplying electrical energy from the power storage system 400 to the lighting device 130 when the insolation amount is insufficient.

The illuminating device 130 can supply light of various wavelengths to sunny plants even at nighttime or when the weather is insufficient.

The frame 110 of the greenhouse 100 and the outer wall formed by the double glass 120 may extend upward from the ground. The roof 140 may be provided at the upper end of the outer wall, Electricity can be produced.

The roof 140 has a first roof 141 on which the solar module 300 is installed and a second roof 141 that is coupled to one end surface of the first roof 141 at a predetermined angle, And a second roof 142 installed on the first roof 141 and the second roof 142 so as to be absorbed by the first solar cell 200 and the solar module 300, And a light diffusion film 150 for diffusing sunlight to transmit the sunlight to the sunny plant.

The first roof 141 may be located in a southward direction with a large inflow of sunlight and direct sunlight may flow directly into the solar module 300 to generate a large amount of electrical energy. In addition, the first roof 141 and the second roof 142 may be formed in various forms.

The light diffusion film 150 is provided on the inner surface of the double glass 120 corresponding to the roof 140 of the greenhouse 100 having the roof 140, The sunlight transmitted through the first solar cell 200 provided in the optical module 300 and the second roof 142 can be diffused and transferred to the sunny plants in the greenhouse 100.

The light diffusion film 150 may be disposed on an inner side surface of the outer wall on which the first solar cell 200 installed on the south side of the greenhouse 100 is installed and a room on the roof 140, The sunlight transmitted through the solar cell 200 without being absorbed can be diffused and transferred to the sunny plant.

The material of the light diffusion film 150 may be an organic material having many light transmittance and transparency. The organic material may be acrylic resins, unsaturated polyester resins, urethane resins, epoxy resins, or melamine resins.

The light diffusion film 150 is formed of a transparent material for light transmittance. When sunlight enters the light diffusion film 150, the light is diffused to induce transmission of light of a desired wavelength band. By using such a light diffusion film 150, not only a short wavelength but also a light absorption of a long wavelength can be greatly improved.

The first solar cell 200, which surrounds the outer wall between the second roof 142 and the double glass 120 of the greenhouse 100, has a function of absorbing sunlight, Sensitized solar cell (DSSC) in which the wavelength and the transmittance of the transmitted light are selected by adjusting the type and thickness of the electrode layer.

When the first solar cell 200 is used over the entire area of the greenhouse 100, it can provide a uniform sunshine condition in the greenhouse 100 compared to a solar cell having a cell spacing. Since the outer wall of the greenhouse 100 may be formed in various shapes using curves or straight lines, the first solar cell 200 may be formed of a flexible material and may be bent.

Here, the dye-sensitized solar cell used in the first solar cell 200 is different from a wafer-type silicon or compound solar cell using a pn junction, and when light having a wavelength of visible light is incident, An oxide semiconductor capable of accepting excited electrons, and an electrolyte that reacts with electrons that return to the cell and work.

Well known dye-sensitized solar cells have been published by Gratzel et al. In Switzerland. The photo-electrochemical solar cell presented by Gratel et al. Is composed of a photosensitive dye molecule capable of absorbing visible light to generate an electron-hole pair, and a nanoparticle titanium dioxide (TiO 2) with dye molecules adsorbed thereon An oxide semiconductor electrode, a counter electrode coated with platinum or carbon, and an electrolyte solution filled therebetween. This photochemical cell has attracted attention because it is cheaper to manufacture than a wafer type solar cell using p-n junction.

In this dye-sensitized solar cell, the generation of electrons through the absorption of light is performed in the dye, and the oxide semiconductor such as titanium dioxide used as the electrode moves the generated electrons to the current collector made of the conductor. It is possible to select the wavelength because the wavelength band which is absorbed by the dye and generates electrons is changed depending on what kind of dye is used.

In addition, the transmittance can be easily controlled by controlling the type and concentration of the dye adsorbed on the electrode or by changing the type and thickness of the electrode layer.

As described above, when the dye-sensitized solar cell is used as the first solar cell 200, the type and concentration of the dye that plays a role of absorbing light, or the type and thickness of the electrode layer to control the wavelength and transmittance of the transmitted light In a dye-sensitized solar cell, it is possible to control the transmitted wavelength only by changing the dyes adsorbed on oxide semiconductors such as TiO 2. It is also possible to control the transmittance by varying the type and thickness of the electrode layer, It is also possible to change. Further, the wavelength used in the power generation for generating electricity in the dye-sensitized solar cell may vary depending on the dye to be used.

The third solar cell 210 may be formed of a dye-sensitized solar cell like the first solar cell 200. The third solar cell 210 has a low inflow amount of sunlight as in the northward direction. When the solar light that flows into the greenhouse 100 through the dye-sensitized solar cell is low, the color of the dye- As shown in FIG.

The third solar cell 210 does not generate a separate wavelength, and efficiency for generating electric energy by utilizing solar light can be increased. A shielding film 500 may be attached to the outside wall of the greenhouse 100 to which the third solar cell 210 is attached to prevent the sunlight from flowing into the greenhouse 100.

The light shielding film 500 may be attached to the inner glass of the outer wall of the greenhouse.

The use of the crystalline silicon solar cell and the amorphous silicon solar cell in the second solar cell 310 is disadvantageous in that the dye-sensitized solar cell such as the first solar cell 200 can not crack or function when the inflow amount of direct light is high It can be installed on the south roof 140 having a large inflow amount of direct light from the outside of the greenhouse 100.

The crystalline silicon solar cell used in the second solar cell 310 is manufactured by cutting a silicon ingot into a thin substrate. The crystalline silicon solar cell is divided into a single crystal type and a polycrystalline type according to a manufacturing method of a silicon ingot. It is basically used as a pn homojunction in solar cells. A single crystal is a high-quality material having a high purity and a low crystal defect density and can achieve a high efficiency, but it is expensive, and a polycrystalline material produces a cell having a degree of efficiency that can be commercialized by treating a relatively low- The theoretical maximum efficiency of this crystalline silicon solar cell is about 25%, and efficiency close to this limit has already been reported at the laboratory level. However, the efficiency of a cell fabricated using monocrystalline or polycrystalline wafers for mass production is about 14% to 17%. At this time, the conversion efficiency of 100% means that 1 KW of power is produced at a width of 1 m 2.

Alternatively, the amorphous silicon solar cell used in the second solar cell 310 may be formed by stacking a p-type amorphous silicon layer, an i-type amorphous silicon layer, and an n-type amorphous silicon layer by absorbing light in a short wavelength region .

The greenhouse 100 is connected to a power storage system 400 (ESS: Energy Storage System) that accumulates electric energy generated by the first solar cell 200, the second solar cell 310, May be provided.

The power storage system 400 is a system in which electric energy generated from the first solar cell 200 attached to the outer wall of the greenhouse 100 and the roof 140 and the second solar cell 310 and the third solar cell 210, It uses electric energy in the time when light energy is supplied and accumulates electric energy so that electric energy can be used even when light energy is not supplied. That is, the environment in the greenhouse 100 can be controlled by not only accumulating the produced electric energy but also distributing it smoothly.

In addition, electricity stored in the power storage system 400 can be supplied to local power supply organizations.
