Description

[0001] Solar power generation apparatus [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar power generation apparatus, and more particularly, to an integrated solar power generation apparatus capable of generating solar power with high efficiency by reflecting and condensing sunlight.

Solar power generation is a power generation method that converts solar light into electric energy, including solar cells, accumulators and power conversion devices. When solar light is irradiated on a solar cell that is made by bonding a P-type semiconductor and an N-type semiconductor, holes and electrons are generated in the solar cell due to the energy of the sunlight. , Electrons are collected toward the N-type semiconductor, and a current flows when a potential difference occurs.

Solar power generation can be used semi-permanently and it is easy to maintain because it uses solar cell, and it is being regarded as a future alternative energy source because it uses pollution-free and inexhaustible solar energy source.

However, in the conventional solar power generation system, a silicon type solar cell which receives direct light is widely used. Since the electric efficiency is about 12 to 14%, the generation area must be relatively wide for sufficient power generation.

Accordingly, even if a solar power generation system is installed in a general house or the like, there is a problem that the utility due to low generation power is inferior, and there is a space restriction that a solar panel should be installed in a place where solar light can be directly irradiated.

Korean Patent No. 10-1208735, filed and registered by the present applicant, discloses a "high-efficiency indoor solar power generation apparatus ", and specifically installed outside the room, A mining unit that removes the solar heat contained in the sunlight and concentrates the sunlight in the visible light region; An optical transmission unit for transmitting sunlight mined through the mining unit to the room; The solar light transmitted through the light transmitting unit is emitted toward a predetermined area so that the light amount per unit area of the solar light scanned in a predetermined area is larger than the light amount per unit area of the sunlight mined through the mining unit, A light emitting unit for collecting light and emitting light toward a predetermined area; A power generation unit provided in a predetermined zone and generating electricity using solar light scanned in a predetermined zone; And a fixed unit that fixes the light emitting unit and the power generating unit to one point in the room. According to this, the portion for mining the sunlight and the portion for generating the mined sunlight are separately arranged outdoors and indoors, It is possible to increase the power generation efficiency by transmitting solar light having a light amount per unit area larger than the light amount per unit area that is mined, to the power generation portion, and there is an advantage that the solar light can be generated beyond the spatial limit or the environmental limit.

However, in this type of photovoltaic device, sunlight mined by a mining unit must be transferred to a power generation unit through an optical transmission unit such as an optical fiber, energy may be lost in the process of transmission, Since the form is very limited, improvement is required.

The base 10 is in the form of a flat plate in the horizontal direction, and the condenser 20 is fixed to the upper surface. The base 10 may be provided with a mounting pillar 50 at the lower end thereof for the installation of the integrated photovoltaic device 1. [

The condenser 20 is formed in the shape of an upwardly concave reflector and is shaped like a parabolic reflector so that the sunlight irradiated by the condenser 20 can be condensed as a single focal point. The surface of the concentrator 20 may be nickel plated, chrome plated or aluminum coated for efficient solar reflection.

A fixed frame 40 for fixing the solar cell module 30 is provided on the base 10 and a plurality of solar cell modules 30 may be installed on the fixed frame 40. The fixed frame 40 is formed to be relatively thin so as to minimize the sunlight irradiated toward the condenser 20 and includes a column 41 that is vertically erected and a column 41 that is formed long in the horizontal direction And a second beam 43 formed in a direction orthogonal to the first beam 42 in the same plane as the first beam 42 and the first beam 42.

The stationary frame 40 is preferably made of metal for ensuring rigidity and for stably supporting the solar cell module 30. [

The solar cell module 30 is fixed to the fixed frame 40 on the base 10 and the condenser 20 and is installed to the focal point of the sunlight condensed in the condenser 20. That is, the solar cell module 30 can be installed after the height thereof is adjusted in consideration of the required amount of power, the size of the condenser 20 as the parabolic reflector, the radius of curvature, and the like. It is preferable that the solar cell module 30 is installed such that the solar cell 33 of the solar cell module 30 is located between the focal distance of the visible light region and the focal distance of the infrared region, It is possible to exhibit the optimal power generation efficiency while excluding it.

The integrated photovoltaic device 1 according to the present invention is configured such that the concentrator 20 for collecting sunlight and the solar cell module 30 for solar power generation are made up of a single device, So that no optical fiber or the like is required for the transfer of the sunlight and the energy loss can be minimized. In addition, the electricity converted in the solar cell module 30 can be transferred through ordinary electric wires, and there is no installation restriction such as optical fibers.

The solar cell module 30 includes a housing 31 and a solar cell 33. 1, the 'A' portion is an enlarged view of the solar cell module 30, and the 'B' portion is an enlarged view of the solar cell module 30 being turned upside down.

The solar cell 33 is a semiconductor device for directly converting solar energy into electric energy, and is installed inside the housing 31 but facing downward. In other words, it is fixed to the housing 31 in such a way as to face the lower side so as to receive the sunlight reflected from the lower side through the condenser 20.

The housing 31 may have the same shape as a box, and houses a solar cell 33 therein, and a through hole 32 for receiving sunlight is formed on a lower side thereof.

The housing 31 may be divided into a case 31a and a lid 31b and the case 31a may be opened in a downward direction and may include a solar cell 33 and other elements for solar power generation And the lid 31b is formed with a through hole 32 so as to cover the case 31a and expose the solar cell 33. [

The through hole 32 is formed to have a size corresponding to the size of the solar cell 33. That is, depending on the size and position of the solar cell 33, solar light reflected by the concentrator 20 can be irradiated to the solar cell 33 only.

For example, if the solar cell 33 is rectangular, the through hole 32 is square, and the solar cell 33 is assembled to the housing 31 in a close contact with the through hole 32, the size of the through hole 32 May be equal to the size of the solar cell 33. Alternatively, when the solar cell 33 is slightly spaced from the through hole 32, the through hole 32 may be formed slightly larger than the solar cell 33.

In any case, it is preferable that the through-hole 32 is formed in a size such that the light condensed and reflected by the condenser 20 can be irradiated (directly irradiated) only to the area of the solar cell 33, 33 to prevent unnecessary heating of elements constituting the solar cell module 30.

At this time, the housing 31 is made of a high-brightness color, especially white, so that the temperature of the inside of the housing 31 can be suppressed as much as possible by reflecting the light other than the light irradiated toward the solar cell 33.
