The present invention relates to a photovoltaic focused generator that focuses sunlight to generate electrical energy, and more particularly, to a photovoltaic focused generator that improves the focusing efficiency of the photovoltaic light and facilitates tracking of the sun. will be.

As a general high-density photovoltaic device, it can be divided into uniaxial type and biaxial type depending on the driving method.

The biaxial type installs a structure including a plurality of reflectors toward the sun, and installs a part including the power generation device at a sufficient distance from the center of the structure with the sun back, and adjusts the reflectors belonging to the structure from side to side. The azimuth and altitude are tracked and light is generated by generating power.

This biaxial method has the advantage of focusing a lot of light in one place, so it is mainly used for solar power generation rather than using solar cells. In addition, there is a disadvantage in that cost and operation are difficult because of the precision required to accurately track the movement of the sun.

On the other hand, the uniaxial type is a device in which the reflectors installed in the transverse direction with respect to the sun's copper wire rotate in the same direction in response to the azimuth of the sun. The solar cell or the solar collector is mounted on the shaft. This device is simple to use because it has a single rotation axis without tracking altitude and is easy to install by forming a colony.It is relatively easy to operate compared to the biaxial type, but the device is large and requires a large space. Because of its high heat, it is being used as a solar-powered device rather than for solar power generation.

Conventional solar photovoltaic devices including such uniaxial or biaxial systems generate heat ranging from at least 300 degrees to thousands of degrees due to high collection speeds, so that heating power generation using solar heat is higher than that of solar cells having a water resistance of 90 degrees.

The excessive heat rises due to the heat generated, which causes a problem such that the battery function is significantly reduced or the life is shortened.

In addition, the low-concentration photovoltaic device, which is being studied in a small number of conventional photovoltaic devices, exhibits a low focusing rate of about 2 times due to a structural problem in which reflectors and solar cells are alternately installed. Since it has a low concentration of solar light efficiency there is a problem that does not obtain a satisfactory power generation efficiency.

The light collecting plate 17 is composed of a solar cell in which the light reflected from the reflecting plate 15 and the auxiliary reflecting plate 19 to be described later is collected, and the light energy thus collected can be converted into electrical energy. Since the specific structure of such a solar cell is a well-known structure, detailed description is abbreviate | omitted. However, the light collecting plate 17 according to the present invention may be formed to have a size between 1/4 and 1/10 times the incident light incident on the reflecting plate 15, and thus may be configured to have a light collecting efficiency of 4 to 10 times. have.

For reference, FIG. 13 is a view illustrating that the light collecting plate 17 is configured to have a light condensing rate of about 10 times the incident light area.

Next, the auxiliary reflecting plate 19 is formed in a planar structure on the inner surface of the end of the curved plate 13, out of the light collecting plate 17 without being reflected by the light collecting plate 17 of the light reflected from the reflecting plate 15 It serves to reflect some light to the light collecting plate 17.

In other words, despite the fact that the government is promoting renewable energy supply projects in the midst of a high march of oil prices due to the expense that consumers must bear, the device according to the present invention is a solar cell price. Compared with the relatively cheap reflector, the solar energy utilization efficiency is increased, thereby motivating the user to save energy and protect the environment.

In addition, the present invention by using a reflector installed at a specific angle to reflect the sunlight while maintaining a certain angle and to prevent the damage to the light collecting plate because the light collecting plate (solar cell) is installed on the bottom so as not to interfere with sunlight At the same time, there is an advantage that more efficient solar power generation is possible.

In addition, the unbalanced light is irradiated on the solar cell by the slight shadow generated during the solar cell's light collection process, and accordingly, a different voltage is generated on each side, thereby lowering the efficiency of the solar cell due to a voltage drop phenomenon. However, since the present invention is configured so that the light collecting plate is installed at a position outside the region where sunlight is incident, so as not to be affected by a shadow or the like, a shadow does not occur inside and condenses solar energy more uniformly. There is an advantage to increase the efficiency.
