Description

Photovoltaic device {Photovoltaic power generation apparatus}

The present invention relates to a photovoltaic device, and more particularly, to a photovoltaic device capable of increasing power generation efficiency by directly transferring heat generated from a photovoltaic module to water.

In general, electricity generating devices can be classified into thermal power generation using fossil fuels such as petroleum or coal, and solar, nuclear, hydro, tidal, and wind power generation depending on the energy source used.

Among these power generation apparatuses, the power generation apparatus using nuclear power has an advantage of generating electricity at a lower cost than thermal power generation, but installation is limited due to environmental pollution and harmfulness of human body due to radiation.

In recent years, facility investments have not been made smoothly due to the disposal of nuclear waste generated after electricity generation.

In addition, in the case of thermal power generation, fossil fuels such as coal and petroleum are used. These fuels not only emit substances polluting the environment when electricity is generated, but also have a high cost of fuel. In addition, in recent years, oil prices have increased due to a decrease in resource reserves. Accordingly, power generation costs have increased, and thus, development of clean energy that does not generate substances polluting the environment is required.

In addition, in recent years, regulations are being enforced around the world to suppress the emission of carbon dioxide. Accordingly, development of a new power generation device without carbon dioxide emission is required.

As such, there is no emission of carbon dioxide, and as a power generation device using clean energy, a power generation device using solar is typical, and in recent years, the development and installation cost of technology have become inexpensive, and its spread is expanding. However, the photovoltaic power generation device has a difference in power generation capacity depending on the generation area and the amount of sunshine, and there are many restrictions on the purchase of land due to the huge use of land in order to install it in a large area. Due to the costly problem, there is a practical difficulty of drawing cooperation of the surrounding residents in order to install a large-scale power generation facility. In particular, in high-latitude regions where there are many restrictions due to residential or agricultural lands and low terrain such as deserts, this problem is more serious and water photovoltaic power generation has been suggested as a viable alternative to overcome this problem.

Therefore, in order to increase the power generation efficiency, it is most important to create a cold and sunny environment.

The problem to be solved according to the present invention is to install a photovoltaic device on the water surface can secure a wide area of land dash in limited land, and can prevent the degradation of power generation efficiency due to heat during power generation In providing.

May be defined. The photovoltaic structure 1000 may transmit electric power generated through photovoltaic power generation to a power company through an underwater cable.

The container 100 may be open at an upper side and a lower side, and may have an empty space at an inner side thereof with a plane and a curved surface connected to each other. The container 100 may be similar to the shape split in half when the capsule-type pills are cut in the longitudinal direction. In addition, the container 100 may be configured in the form of a vessel that can generate buoyancy. The container 100 may have a length of about 25 to 30M in the X direction, about 3 to 4M in the Y direction, and about 2 to 3M in the Z direction. The container has been shown as an embodiment in which a plurality of photovoltaic modules are mounted, but may have a minimum unit length for mounting a photovoltaic module of about 2 meters. The vessel may be adjusted in length so that it is not broken by forces hitting high waves in bad weather.

The container 100 may be buoyant in the water with a buoyancy calculated dynamically with the shape and weight of the container 100. Since the container 100 is a part directly contacting the seawater or fresh water in the solar conversion structure 1000, the container 100 should have good corrosion resistance to prevent corrosion, and may be made of a high strength material in preparation for waves and various bad weather. The container 100 is generally metal, plastic, and more specifically, stainless steel, aluminum, fiber reinforced plastic (FRP), sheet molding compound (SMC), polyethylene, or polystyrene may be used. The outer surface contacting the water in the container 100 may be painted with a material having high corrosion resistance.

The protective plate 200 may be located in an open portion of the upper portion of the container 100. The protective plate 200 may be coupled to the container 100 in a manner that seals the container 100 so that the inside of the container 100 is not flooded from the water phase. The protective plate 200 may protect the reflective plate 500 and the photovoltaic module 400 located in the container 100 from an external environment. The protective plate 200 may be coupled and opened and closed by a hinge type on one side of the container 100 in the longitudinal direction (X-axis), and may be driven in an actuator manner through electric, hydraulic, and compressed air. 1 and 2 it is noted that the protective plate 200 is not shown separately to show the configuration inside the container 100.

The protective plate 200 may be made of a material of a transparent material so that light generated from the sun is incident into the container 100. The container 100 may be made of a material such as tempered glass, polyethylene, polypropylene, a silicone-based transparent material including polydimethylsiloxane (PDMS), or polymethyl methacrylate (PMMA).

The protective plate 200 may be configured in the shape of a lens. Therefore, by collecting the light from the sun it can increase the amount of light incident to the photovoltaic module 400.

The heat sink 300 may be located at an open portion of the lower portion of the container 100. The heat sink 300 may be coupled to the container 100 in a manner to seal the container 100 so that the inside of the container 100 is not submerged from the water phase. The heat sink 300 may be configured in a rectangular plate shape, but the shape is not limited thereto. In this embodiment, a plurality of solar power module 400 is shown as being located on one heat sink 300, but each heat sink corresponding to each of the solar power module 400 may be located. The heat sink 300 may be disposed substantially parallel to the water surface when there is no shaking due to an external environment when the solar conversion structure 1000 is lifted in seawater or freshwater to perform its function.

In addition, the heat dissipation plate 300 and the protection plate 200 may be substantially spaced apart by the height of the container 100 to be disposed substantially parallel to each other.

The photovoltaic module 400 is positioned on an upper portion of the heat sink 300, and a lower portion of the heat sink 300 may directly contact seawater or fresh water. Accordingly, the heat sink 300 may be made of a metal material having high thermal conductivity and high corrosion resistance in water in order to quickly transfer heat generated by the photovoltaic module 400 to seawater or fresh water.

The method of increasing the power generation efficiency during solar power generation is a direct method to increase the power generation efficiency based on the material characteristics of the PV cell itself. However, due to technical limitations, the power generation efficiency remains between about 10 to 40%. Physically, the photovoltaic module 400 has a lower voltage as temperature increases, resulting in lower power generation efficiency. Therefore, a method of increasing power generation efficiency by lowering the temperature of the photovoltaic module 400 by rapidly removing heat generated from the photovoltaic module 400 may be used.

Since the heat sink 300 is in direct contact with seawater or fresh water having a very high heat transfer coefficient compared to air, heat generated by the solar power module 400 may quickly escape into the seawater or freshwater.

In addition, in the solar conversion structure 1000 according to the embodiment of the present invention, the heat sink 300 and the solar power generation module 400, which are heavy components in the solar conversion structure 1000, are formed in the container 100. It may be located at the bottom. This is due to the high density of photovoltaic modules placed on low-density objects such as plastics, which are already commercially available, such that the center of buoyancy is lower than the center of gravity. This is a design structure to solve problems such as overturning. This lowers the center of gravity in the photovoltaic structure 1000 according to an embodiment of the present invention than the buoyancy center, compared to the photovoltaic devices previously disclosed in the water, especially in the sea water affected by the algae, especially the solar conversion structure ( 1000) can be installed and operated stably.

The reflector 500 is a light that is not incident to the photovoltaic module 400 of the light incident through the protective plate 200 is incident to the reflector 500 to be reflected to enter the photovoltaic module 400 again. Can function. The reflective plate 500 may select any one of a metal and a metal alloy including aluminum, copper, and the like, and may be manufactured by coating a metallic material on a plastic or the like.

4 is a cross-sectional view of a solar conversion structure according to another embodiment of the present invention.

Referring to FIG. 4, the position and structure of the solar conversion structure 1200 according to another embodiment of the present invention are different from those of the solar conversion structure 1000 disclosed in FIGS. 1 to 3. There is. Therefore, the embodiment corresponding to FIG. 4 will be described with reference to the reflecting plate 520, and other components will be borrowed from the matters described with reference to FIGS. 1 to 3.

The reflective plate 520 may be disposed to contact the inside of the container 100 to surround the inner surface of the container 100. In more detail, the reflective plate 520 may be formed to have a predetermined thickness along the inner surface of the container 100 and may be formed up to a position from the bottom of the protection plate 200 to the heat sink 300. Accordingly, the shape of the reflector plate 520 may have a shape substantially the same as that of the container 100, and thus may have an arc shape.

The reflective plate 520 having the same configuration as the present embodiment has no separation distance from the container 100, and thus, when the external environmental condition is deteriorated and fluidity such as shaking is increased, the plate type reflective plate 500 disclosed in FIGS. 1 to 3 is increased. Compared to), it is possible to stably maintain the solar conversion structure 1200.

The reflective plate 520 may be formed on the inner surface of the container 100 by processing a material to have a predetermined thickness, but may be manufactured by plating on the inner surface of the container 100.

5 and 6 are cross-sectional views of a solar conversion structure according to another embodiment of the present invention. FIG. 6 is a cross-sectional view taken along the line BB ′ of FIG. 5.

5 and 6, the solar cell converting structure 1400 according to another embodiment of the present invention has a water reservoir 600 compared to the solar cell converting structure 1000 disclosed in FIGS. 1 to 3. There is a difference in the additional configuration. Thus, in the embodiment corresponding to Figures 5 and 6 will be described with respect to the water reservoir 600, the parts related to other components will be borrowed from the details described in Figures 1 to 3.

When the solar conversion structure 1400 is located in the water phase, the water reservoir 600 may adjust the submerged depth of the solar conversion structure 1400 by adjusting buoyancy according to the water environment by injecting or removing water in the water. have. For example, when the solar conversion structure 1400 is shaken due to the wind at sea, the amount of seawater injected into the water reservoir 600 is increased so that the solar conversion structure 1400 is further submerged below the water surface. The solar conversion structure 1400 may be protected from waves and other external objects generated from above.

The water reservoir 600 should be positioned spaced apart from the heat sink 300 by a predetermined distance. When the solar conversion structure 1400 is installed in the water phase, since the heat sink 300 must be in direct contact with water, the heat dissipation function may not be optimized when located in the water reservoir 600. Therefore, the water reservoir 600 should be spaced apart from the heat sink 300 so that the heat sink 300 is in direct contact with water under the water surface. Of course, the heat sink 300 may be in contact with the water introduced into the water reservoir 600 to perform a heat dissipation function, but the water reservoir 600 may not be stored in some cases, the water reservoir 600 Where the heat sink 300 is located in the heat radiation effect may not be high.

The water reservoir 600 may introduce water through the inlet 610 in the water. The inlet 610 may be disposed under the water surface to allow water to flow in when the inlet 610 is opened. In order to drain water from the water reservoir 600, when air is injected into the water reservoir 600 through an air inlet pipe (not shown) configured between the container 100 and the water reservoir 600, The water above the surface of the water can escape.

9 is a plan view of a photovoltaic device according to an embodiment of the present invention.

Referring to FIG. 9, in the photovoltaic device 1500 according to an embodiment of the present invention, a plurality of photovoltaic conversion structures 1000 may be interconnected. Again, the photovoltaic structure 1000 may be a photovoltaic device, and a plurality of photovoltaic devices 1000 may be connected to be referred to as a photovoltaic device 1500.

The plurality of solar conversion structures 1000 may be arranged in a row with each other. The containers of each solar conversion structure 1000 may be connected through the inter-containment fastening part 700. The construction method of the fastening part 700 may use other known techniques. For example, the connecting plate 750 may be welded between the mutually opposing containers of the first photovoltaic structure 1010 and the second photovoltaic structure 1020 or may be interconnected through mechanical assembly such as a bracket. And, through the connecting plate 750 it is possible to secure a moving space of the worker for the maintenance / repair of the photovoltaic device 1500. When the photovoltaic device 1500 adopts a multi-hulled structure interconnecting a plurality of photovoltaic conversion structures 1000, only a single photovoltaic conversion structure 1000 is in a water phase, and sunlight is exposed from a harsh external environment such as a typhoon. The power generation apparatus 1500 can be stably operated. Therefore, the arrangement and operation of the solar conversion structure 1000 in a matrix may have an excellent effect on the movement of the worker, stable response of the external environment, and increase in power generation capacity. However, the numerical value of the matrix of the photovoltaic converting structure depends on the local characteristics and economic characteristics such as the area of the site where the photovoltaic device 1500 is installed, weather conditions, power generation capacity and the like.

The electric motor may be driven by receiving electric power from the energy storage system, and supply the pneumatic and hydraulic pressure to the connecting plate 750 through the pressure regulator connected to the electric motor and the electric motor, and adjust the supply amount thereof. Since the process of supplying or adjusting the amount of pneumatic or hydraulic pressure to the connecting plate 750 does not require fast response characteristics as when driving a robot or a machine tool, a small / low output electric motor and a pressure regulator driven therefrom The function can be performed as (not shown). The pressure regulator may also deliver pneumatic or hydraulic pressure to the connecting plate 750 through a pneumatic / hydraulic line (not shown), or adjust the pneumatic and hydraulic pressure in the connecting plate.

When the weather conditions are good at sea, the connecting plate 750 is maintained in a high rigidity state by the compressed air, it can be the same as the movement of the calm water surface. However, when the difference in the height of the water surface such as high waves in bad weather increases, if the rigidity of the photovoltaic device is high, there is a possibility of being crushed or overturned by the impact from the waves. Therefore, when bad weather is expected or arrived, it may be changed to a flexible state by controlling the flow rate such as removing compressed air injected into the connecting plate 750. In this case, the photovoltaic structure 1000 connected to the connecting plate 750 may move while following the movement of the wavefront, and may prevent breakage or overturning of the photovoltaic device.

The power transmission device 800 may be further positioned in the solar conversion structure 1000 that is positioned outside the solar cell apparatus 1500. The power train 800 may be another device that can move the photovoltaic device 1500 in the water body, for example a propeller propellant. The power transmission device 800 may be configured in plural and may be driven in whole or in part only depending on a situation. The photovoltaic device 1500 may rotate in place through the power transmission device 800, and may move to any point set by an operator operating the photovoltaic device 1500. The photovoltaic device 1500 may have a mobility through the power transmission device 800 so that the weather environment may deteriorate in a water phase (typhoon, Nether) to escape a harsh environment.

In addition, the power transmission device 800 may rotate the photovoltaic device 1500 underwater so that the photovoltaic device 1500 tracks the movement of the sun. The power train 800 may provide power to the photovoltaic device 1500 to follow the movement trajectory of the sun.

If the position is a result value and transmits it to the power transmission device 800, the photovoltaic device 1500 may automatically rotate by date / time and receive the maximum sunlight. The photovoltaic device 1500 may rotate along the trajectory of the sun and brake or adjust the movement of the power train 800 according to a signal from a position sensor.

In addition, the heat dissipation plate 2300 and the protection plate 2200 may be substantially spaced apart from each other by a height of the first container 2100 to be substantially parallel to each other.

A photovoltaic module 2400 is positioned on an upper portion of the heat sink 2300, and a lower portion of the heat sink 2300 may directly contact seawater or fresh water. Therefore, the heat dissipation plate 2300 may be made of a metal material having high thermal conductivity and high corrosion resistance in water to quickly transfer heat generated by the solar power generation module 2400 to seawater or fresh water. Copper or aluminum may be adopted as the representative metal.

Since the heat sink 2300 is in direct contact with seawater or fresh water having a very high heat transfer coefficient as compared with air, heat generated by the solar power module 2400 may quickly escape into the seawater or fresh water.

In addition, in the solar conversion structure 2000 according to the embodiment of the present invention, the heat-dissipating plate 2300 and the solar power generation module 2400, which are heavy components in the solar conversion structure 2000, are positioned at the bottom of the container. can do.

Since the second container 3100 is in direct contact with seawater or fresh water, the second container 3100 should have good corrosion resistance to prevent corrosion, and may be made of a high strength material in preparation for waves and various bad weather conditions. The container is generally metal or plastic, and more specifically, stainless steel, aluminum, fiber reinforced plastic (FRP), sheet molding compound (SMC), polyethylene or polystyrene may be used.
