염료감응 태양전지를 포함하는 태양광 창호{Solar window frame comprising dye-sinsitized solar cell}Solar window frame comprising dye-sinsitized solar cell

본 발명은 염료감응 태양전지를 포함하는 태양광 창호에 관한 것으로, 보다 상세하게는 내부에 구비된 염료감응 태양전지를 투과한 빛이 염료 자체의 빛에 의하여 영향 받지 않는 염료감응 태양전지를 포함하는 태양광 창호에 관한 것이다. The present invention relates to a solar window including a dye-sensitized solar cell, and more particularly includes a dye-sensitized solar cell that the light transmitted through the dye-sensitized solar cell is not affected by the light of the dye itself. It is about a solar window.

염료감응 태양전지 중에서 대표적인 것으로는 1991년도 스위스 국립 로잔 고등기술원의 마이클 그라첼(Michael Gratzel) 등이 개발한 나노입자 산화티타늄을 이용한 염료감응 태양전지가 있다. 이 염료감응 태양전지는 기존의 실리콘 태양전지에 비해 제조단가가 저렴하고 전극이 투명하여 건물 외벽 유리창이나 유리온실 등에 응용이 가능하다는 이점이 있으나, 광전변환 효율이 낮아 실제 적용에는 제한이 있다.A typical dye-sensitized solar cell is a dye-sensitized solar cell using nanoparticle titanium oxide, which was developed by Michael Gratzel of the Swiss National Lausanne Institute of Technology in 1991. This dye-sensitized solar cell has the advantage that the manufacturing cost is cheaper than the conventional silicon solar cell, and the electrode is transparent, so that it can be applied to a glass wall or a glass greenhouse of a building, but the photoelectric conversion efficiency is low, and thus the practical application is limited.

이러한 염료감응 태양전지는 염료분자가 흡착된 나노결정 산화물필름이 코팅된 투명의 전도성 전극, 금속 백금 등이 코팅된 상대전극 및 산화-환원의 작용을 하는 전해질로 구성된다. 이와 같은 구성을 갖는 염료감응 태양전지는 하나의 기판에 하나의 염료감응 태양전지를 구비시켜 사용하거나, 하나의 기판 위에 다수개의 염료감응 태양전지를 서로 연결시켜 모듈형태로 사용하게 된다. 이와 같은 종래의The dye-sensitized solar cell is composed of a transparent conductive electrode coated with a nanocrystalline oxide film on which dye molecules are adsorbed, a counter electrode coated with metal platinum, and an electrolyte that functions as a redox. The dye-sensitized solar cell having such a configuration is used by having one dye-sensitized solar cell on one substrate or by connecting a plurality of dye-sensitized solar cells on one substrate to be used in a module form. Such conventional

염료감응 태양전지를 다수개 연결설치한 염료감응 태양전지 모듈은 주로 건자재 일체형 광전변환(BIPV,building integrated photovoltaic) 분야에 적용된다. The dye-sensitized solar cell module, which is installed with a plurality of dye-sensitized solar cells, is mainly applied to the building integrated photovoltaic (BIPV) field.

도 1 및 2는 종래 기술에 따른 염료감응 태양전지의 정면도 및 단면도이다.1 and 2 are a front view and a cross-sectional view of a dye-sensitized solar cell according to the prior art.

도 1 및 2를 참조하면, 대면적 제트-시리즈(Z-series) 형태의 직렬 모듈로 제작되어, 사용된 염료감응 태양전지가 개시된다. 상기 염료감응 태양전지 모듈은 두 개의 판상 투명전극으로서 제 1 기판(2) 및 제 2 기판(4)이 서로 접합된 샌드위치 구조를 갖고, 하나의 투명전극인 제 1 기판(2)의 이면에 이산화티타늄 등으로 구성된 도전성 제 1 전극(6)을 구비하고, 다른 하나의 투명전극인 제 2 기판(4)에 백금 등으로 구성된 상대전극인 제 2 전극(8)을 구비하고, 상기 제 1 전극(6) 및 제 2 전극(8)이 각각 구비된 제 1 기판(2) 및 제 2 기판(4) 사이의 공간에 전해질(18)이 충진된 형태를 하나의 단위 셀(cell)로 하여 다수의 셀을 금속 그리드(10)로 서로 연결 설치하여 구성한다. 이때, 상기 그리드(10)는 통상적으로 전해질(18)에 취약하므로 상기 그리드(10)의 외부를 밀봉부재(14)로 감싸 전해질(18)과 접촉되는 것을 방지하고, 전체 염료감응 태양전지 모듈을 구성하는 염료감응 태양전지 중 외측에 위치하는 염료감응 태양전지의 벽면을 밀봉부재(14)로 마감시켜 전해질(18)이 외부로 누액되는 것을 방지한다. 또한, 상기 각각의 염료감응 태양전지의 사이에 구비되는 그리드(10)와 이웃하게 기판(2, 4) 표면에 코팅된 도전성 필름(22)에 에칭부(16)를 구비시켜 염료감응 태양전지 내부에서 발생하는 전자가 다른 염료감응 태양전지로 병렬로 흐르지 않도록 한다. 한편, 상기 금속 그리드(10)는 염료감응 태양전지인 셀의 경계면으로서, 상기 셀의 일 측 벽면으로부터 이에 대향되는 타 측 벽면까지 연장되도록 연결 설치되어 셀, 즉 염료감응 태양전지에 충진된 전해질(18)이 다른 염료감응 태양전지로 이동되지 못하도록 구성된다. 그러므로 상기 염료감응 태양전지 각각에 전해질(18)을 주입하기 위해서는 해당 염료감응 태양전지마다 전해질 주입구(12)가 별도로 두 개 구비된다.Referring to FIGS. 1 and 2, a dye-sensitized solar cell manufactured by using a series module of a large area Z-series type is disclosed. The dye-sensitized solar cell module has a sandwich structure in which the first substrate 2 and the second substrate 4 are bonded to each other as two plate-shaped transparent electrodes, and is discretized on the rear surface of the first substrate 2 as one transparent electrode. A conductive first electrode 6 made of titanium or the like, and a second electrode 4 made of platinum or the like on a second substrate 4, which is another transparent electrode, and the first electrode ( 6) A plurality of unit cells are formed in which the electrolyte 18 is filled in the space between the first substrate 2 and the second substrate 4 provided with the second electrode 8, respectively. The cells are connected to each other by the metal grid 10 and are installed. At this time, since the grid 10 is typically vulnerable to the electrolyte 18, the outside of the grid 10 is wrapped with a sealing member 14 to prevent contact with the electrolyte 18, and the entire dye-sensitized solar cell module The wall surface of the dye-sensitized solar cell positioned outside of the dye-sensitized solar cell is closed with the sealing member 14 to prevent the electrolyte 18 from leaking to the outside. In addition, the etching unit 16 is provided on the conductive film 22 coated on the surface of the substrates 2 and 4 adjacent to the grid 10 provided between the dye-sensitized solar cells, thereby providing the inside of the dye-sensitized solar cell. Prevent electrons from flowing in parallel to other dye-sensitized solar cells. Meanwhile, the metal grid 10 is a boundary surface of a cell which is a dye-sensitized solar cell, and is connected to extend from one side wall of the cell to the other side wall opposite to the cell, that is, an electrolyte filled in a cell, that is, a dye-sensitized solar cell ( 18) is prevented from being transferred to other dye-sensitized solar cells. Therefore, in order to inject the electrolyte 18 into each of the dye-sensitized solar cells, two electrolyte injection holes 12 are provided for each dye-sensitized solar cell.

이와 같은 염료감응 태양전지는 건물 창호 등에 구비되어, 실외로 조사되는 빛을 전기로 변환시킨다. 하지만, 염료감응 태양전지에서 색을 띠게 되는 염료는 일반적으로 붉은 색을 나타내며, 이 중 가장 일반적인 염료는 N719로 지칭되는 염료이다. 이와 같이 붉은 색의 염료를 사용하여 제조된 염료감응 태양전지는 적갈색을 나타내며, 따라서, 이와 같은 염료감응 태양전지를 건물 창호 등에 사용하는 경우, 이를 투과한 빛은 붉은 계열을 띠게 된다. 따라서, 사용자는 푸름 색 계열의 채광 빛에 비하여 붉은 색 계열의 채광 빛에는 피로감을 느끼게 된다. Such a dye-sensitized solar cell is provided in a building window or the like, and converts light emitted to the outside into electricity. However, dyes that become colored in dye-sensitized solar cells generally exhibit a red color, the most common of which is a dye called N719. The dye-sensitized solar cell manufactured using the red dye as described above exhibits reddish brown color. Therefore, when the dye-sensitized solar cell is used in a building window or the like, the light transmitted through the dye-sensitized solar cell is reddish. Accordingly, the user may feel fatigue in the red light of the light compared to the blue light of the light.

더 나아가, 푸른 색 계열의 염료를 사용하는 경우, 효율이 떨어지고, 더 나아가 전해질의 구성요소인 요오드가 주황을 띠는 점을 고려하여 볼 때, 설령 푸른 색 계열의 염료가 사용되어도, 실제 염료감응 태양전지를 투과한 빛이 푸른 색을 띠는 것은 거의 불가능하다. Furthermore, in the case of using a blue dye, the efficiency is lowered, and furthermore, considering that the iodine, which is a component of the electrolyte, is orange, even if a blue dye is used, the actual dye sensitivity It is almost impossible for the light transmitted through the solar cell to have a blue color.

따라서, 본 발명이 해결하려는 과제는 사용자가 불편함과 피로감을 느끼는 붉은 색 계열의 투광 빛을 제거하고, 원하는 투광 빛, 특히 푸른 색 계열의 투광 빛을 구현할 수 있는 염료감응 태양전지 기반의 태양광 창호를 제공하는 것이다. Therefore, the problem to be solved by the present invention is a dye-sensitized solar cell-based solar light that can remove the red-based floodlight that the user feels uncomfortable and tired, and can implement a desired floodlight, in particular a blue-based floodlight To provide a window.

In order to solve the above problems, the present invention is a solar window including a dye-sensitized solar cell facing the upper substrate and the lower substrate spaced apart at a predetermined interval, the electrolyte is filled between the upper substrate and the lower substrate, The window and doors are two glass spaced at predetermined intervals; And a dye-sensitized solar cell provided between the two glasses, wherein any one of the glasses has a specific color, and provides a solar window including the dye-sensitized solar cell.

본 발명의 일 실시예에서 상기 유리는 실내 방향으로의 유리이다.In one embodiment of the invention the glass is glass in the room direction.

본 발명에 따른 태양광 창호는 내부에 구비된 염료감응 태양전지를 투과한 빛이 염료 자체의 빛에 의하여 영향 받지 않는다. 따라서, 사용자가 원하는 색으로 염료감응 태양전지의 투광 빛을 결정할 수 있으므로, 특히 건물 외벽이나 창호에 사용되는 경우, 효과적이다. 아울러, 투과되는 빛을 반사함으로써 전지 효율 향상 또한 기대할 수 있다.

도 4를 참조하면, 염료감응 태양전지의 양 측면에 구비되는 유리 중 어느 하나(310) 상에는 필름(340)이 적층된다. 여기에서 상기 필름은 염료감응 태양전지를 거치면서 외부로부터 투과되는 빛을 수광하며, 상기 빛 중 특정 파장의 빛을 걸러내고, 나머지 파장의 빛을 투과시키는 특성을 갖는다. 특히, 본 발명자는 태양광 창호와 같이 실외와 실내의 경계에 설치되는 건물일체형 태양광 시스템에서 실내 방향의 유리에 특정 파장의 빛을 걸러내고, 반사시키는 필름을 구비시킴으로써 실내 방향으로 투과된 빛의 색을 염료 자체에 의하여 영향 받지 않게 하며, 더 나아가, 필름에서 반사된 빛으로 전지 효율을 향상시켰다. 따라서, 반사되는 빛을 극대화하기 위하여, 상기 필름은 염료감응 태양전지(330)의 기판(331)과 유리(310) 사이에 적층되는 것이 바람직하다. Referring to FIG. 4, the film 340 is stacked on any one of the glasses 310 provided on both sides of the dye-sensitized solar cell. Herein, the film receives light transmitted from the outside while passing through the dye-sensitized solar cell, filters out light of a specific wavelength, and transmits light of the remaining wavelengths. In particular, the inventors of the present invention provide a film that filters and reflects light of a specific wavelength on glass in an indoor direction in a building integrated solar system installed at a boundary between an outdoor and an indoor space such as a solar window, thereby providing The color was not affected by the dye itself, and furthermore, the cell efficiency was improved by the light reflected from the film. Therefore, in order to maximize the reflected light, the film is preferably laminated between the glass 310 and the substrate 331 of the dye-sensitized solar cell 330.
