Description

Photovoltaic Cell System Having Light Focusing Efficiency Improving Structure

The present invention relates to a solar cell system including a light collecting efficiency improving structure, and more particularly, to a solar cell system in which power generation efficiency is improved by using a light collecting unit disposed independently of a solar cell panel.

Solar power generation is a power generation method that directly converts sunlight into electrical energy using solar cells without the aid of a generator.

Recently, interest in solar power generation is increasing with the improvement of semiconductor efficiency, and efforts are being made to efficiently collect solar light to improve power generation efficiency.

Korean Patent Application Laid-Open No. 10-2009-0015019 discloses a solar collecting panel technology that changes the angle of a solar cell panel according to the angle of incident light in order to collect more light on the surface of the solar cell.

The conventional solar collecting panel rotates to face the sun, so the power generation efficiency can be improved, but there is a disadvantage in that a power mechanism for detecting the incident direction of sunlight and rotating the panel is separately required.

In addition, Korean Patent No. 10-1092428 discloses a technology of a condenser capable of condensing sunlight using a parabolic mirror.

However, this conventional condenser technology has a problem in that the light condensing efficiency is lowered as the optical paths of the light incident on the parabolic mirror and the reflected light overlap each other, resulting in loss of light.

In order to solve this problem, as shown in FIG. 1 , a parabolic reflector has been developed that surrounds the side of the solar cell and reflects the sunlight to the light incident surface of the solar cell and condenses it.

In order to use the parabolic reflector shown in FIG. 1, it must be fixed by being spaced apart from the front surface of the solar cell by a predetermined distance, thereby requiring a separate support structure. In addition, there is a problem that the reflector structure collides with the solar cell due to external environmental factors such as wind or typhoon, thereby damaging the solar cell.

On the other hand, in the case of a solar cell panel according to the prior art, a plurality of solar cell units are arranged at a predetermined interval on a plate-shaped support member. At this time, a frame is mounted on the edge of the plate-shaped support member to be bound to a column installed on the ground surface.

In this case, since the solar cell unit cannot be disposed in an area corresponding to the frame surrounding the edge of the solar cell panel, there is a problem in that solar power cannot be generated as much as the area occupied by the frame.

On the other hand, the solar cell panel according to the prior art is mounted on the upper part of the support installed in the corresponding area. In this case, the support installed in the corresponding area is constructed in a specific direction and at a specific angle so that the solar cell panel can absorb sunlight as much as possible.

In the area where the solar cell panel is installed, a plurality of supports are installed at regular intervals. In this case, sunlight incident on the spaced apart space of the support cannot be incident on the solar cell panel. For this reason, although a technology for installing a plurality of supports as close to each other as possible has been developed, there is a problem in that solar cell panels installed adjacent to each other interfere with each other to form shades, and on the contrary, solar power generation efficiency is lowered.

Accordingly, there is a need for a technique capable of solving the above-mentioned problems according to the prior art.
