Problems solved by technology

However, since the foldable module consists of only two modules, and adjacent photovoltaic cell modules are used as round rug connection with shaped bolts, so this structure can only be used for flat types
[0006] In addition, in the case where a photovoltaic cell module manufactured by connecting a plurality of unit cells in series and / or in parallel is to be arranged in a large-area flat type, a large output may not be generated in a narrow space, and the reflection of each unit module Reflected light may not be reabsorbed, and transmission and storage may be inconvenient
In order to solve the above limitations, Korean Registered Patent No. 10-1730562 discloses a structure for easily assembling and disassembling a unit module of a photovoltaic cell module, but does not disclose improving power generation efficiency for the same installation area and increasing reabsorbed reflected light structure

Embodiment approach 1

[0103] will use figure 1 (a) to (c) describe the configuration of the module according to the first embodiment of the present invention.

[0104] figure 1 (a) is a diagram showing a configuration of a module in which a plurality of rectangular unit modules are mounted on a support including a bent portion having a triangular pipe shape at an upper portion thereof.

[0105] The support including the triangular protrusion is built on an installation site such as a plain, a slope, a roof, an outdoor facility, or a public house. The support includes a post supported by the ground or wall surface and a support connected to the post and including a triangular protrusion. A photovoltaic cell module is mounted on the surface of the triangular protrusion.

[0106] like figure 1 As shown in (a) of (a), the photovoltaic cell unit module is configured such that a plurality of photovoltaic cells are arranged in a row, and surface electrodes and rear electrodes of cells adjacent to each...

Embodiment approach 2

[0117] figure 2 is a diagram illustrating a method of using a flexible photovoltaic cell that can obtain a curved surface effect by using a typical flat support.

[0118] Flexible photovoltaic cells include thin silicon photovoltaic cells and thin film photovoltaic cells. That is, since conventionally commonly used silicon photovoltaic cells have a wafer thickness of about 180 μm, the silicon photovoltaic cells have insufficient flexibility and elasticity and thus are easily broken during bending. However, when thin-film silicon cells are applied, the wafer thickness can be reduced to 100 μm or less, and flexibility and elasticity can be increased. Therefore, bending equal to or greater than 60° can be performed.

[0119] Thin Film Photovoltaic Cells Flexible photovoltaic cells can be manufactured by using a metal substrate such as a polymer sheet or a stainless steel sheet as a substrate so that the shape of the cell can be easily deformed.

[0120] Therefore, when a thin...

Embodiment approach 3

[0124] image 3 is a diagram showing a thin film photovoltaic cell manufactured on a flexible substrate including a plurality of uneven portions through an embossing process and a unit module including the thin film photovoltaic cell.

[0125] The embossing treatment method includes forming multiple embossments on the surface of a substrate by using an apparatus for treating embossing on the surface of a polymer sheet such as polyimide or a metal sheet such as a stainless steel sheet, copper sheet, and zinc sheet. method for uneven parts. The embossing treatment method can generally be carried out in the following manner: a flexible substrate is inserted between and passes through the upper and lower embossing rollers, and the embossing formed on the outer peripheral surface of the rollers is removed by applying heat or pressure. Or the embossing is transferred to the substrate to form a plurality of uneven parts. In addition, embossing processing methods include laser engra...

Abstract

The present invention relates to a structure of a photovoltaic cell module capable of improving power generation output by increasing a light receiving area and a sunshine duration. The photovoltaic cell module includes a crystalline photovoltaic cell, such as monocrystalline silicon / polycrystalline silicon or gallium arsenide (GaAs), and a cadmium telluride (CdTe), copper indium gallium selenide(CIGS) / copper indium selenide (CIS) or fuel sensitive thin film photovoltaic cell. A photovoltaic cell module according to the present invention includes a support unit and a plurality of photovoltaiccell modules mounted on the support unit, and has a protruding shape bent in a predetermined shape toward a surface.

Description

technical field [0001] The present invention relates to a photovoltaic cell module capable of increasing power generation output per unit area in which the photovoltaic cell module is installed, compared with typical photovoltaic cell modules. Photovoltaic cell modules include crystalline photovoltaic cells such as monocrystalline silicon, polycrystalline silicon, and gallium arsenide (GaAs), as well as cadmium telluride (CdTe), copper indium gallium selenide (CIGS) / copper indium selenide (CIS), and fuel-sensitive thin-film PV. Background technique [0002] Crystalline and thin-film photovoltaic cell technology is a clean energy alternative to typical electrical energy sources. Although continuously distributed, this technology has been limited in commercialization due to the high cost of the power generation unit compared to typical methods such as coal-fired power generation and nuclear power generation. Among them, compared with crystalline silicon photovoltaic cells th...
