염료감응 태양전지 모듈을 이용한 창문용 액정 패널 Window liquid crystal panel using dye-sensitized solar cell module
본 발명은 창문용 액정 패널에 관한 것으로, 보다 구체적으로, 염료감응 태양전지(Dye-Sensitized Solar Cell: DSSC) 모듈을 이용하여 생성된 전원으로 창문용 액정 패널을 구동할 수 있는 염료감응 태양전지 모듈을 이용한 창문용 액정 패널에 관한 것이다.The present invention relates to a liquid crystal panel for a window, and more specifically, a dye-sensitized solar cell module capable of driving a window liquid crystal panel with a power generated using a dye-sensitized solar cell (DSSC) module. It relates to a window liquid crystal panel using.
1991년도 스위스 로잔공대(EPFL)의 마이클 그라첼(Michael Gratzel) 연구팀에 의해 염료감응 나노입자 산화티타늄 태양전지가 개발된 이후, 이 분야에 관한 많은 연구가 진행되고 있다. 염료감응 태양전지는 기존의 실리콘계 태양전지에 비해 제조단가가 현저하게 낮기 때문에 기존의 비정질 실리콘 태양전지를 대체할 수 있는 가능성을 가지고 있으며, 또한, 염료감응 태양전지는 실리콘 태양전지와 달리 가시광선을 흡수하여 전자-홀 쌍을 생성할 수 있는 염료분자, 및 생성된 전자를 전달하는 전이금속 산화물을 주요 구성 재료로 하는 광전기화학적 태양전지이다.Since the development of dye-sensitized nanoparticle titanium oxide solar cells by Michael Gratzel and colleagues at the Lausanne Institute of Technology (EPFL) in 1991, much work has been done in this area. Dye-sensitized solar cells have the potential to replace conventional amorphous silicon solar cells because their manufacturing cost is significantly lower than that of conventional silicon-based solar cells. It is a photoelectrochemical solar cell whose main constituent material is a dye molecule capable of absorbing to generate an electron-hole pair, and a transition metal oxide for transferring the generated electrons.
일반적인 염료감응 태양전지의 단위 셀 구조는 투명한 기판과 그 투명기판의 표면에 각각 형성되는 도전성 투명전극을 기본으로 하여, 제1 전극에 해당하는 일측의 도전성 투명전극 위에는 그 표면에 염료가 흡착된 전이금속 산화물 다공질 층이 형성되고, 제2 전극에 해당하는 타측 도전성 투명전극 위에는 촉매 박막전극이 형성되며, 상기 전이금속 산화물, 예를 들면, TiO2, 다공질 전극과 촉매박막전극 사이에는 전해질이 충진되는 구조를 갖는다. 즉, 염료감응 태양전지는 정공 전달 매개체로서 전해질을 사용하며, 이러한 염료감응 태양전지의 전해질 의존성은 전해질의 확산속도에 의존하며, 확산속도는 액체상태의 유기용매나 이온액체전해질이 반고체형이나 고체형에 비교하여 확산속도가 크기 때문에 광전변환 효율 성능이 우수하다.The unit cell structure of a general dye-sensitized solar cell is based on a transparent substrate and a conductive transparent electrode formed on the surface of the transparent substrate, respectively, and a transition of dye adsorbed on the surface of the conductive transparent electrode on one side corresponding to the first electrode A metal oxide porous layer is formed, a catalyst thin film electrode is formed on the other conductive transparent electrode corresponding to the second electrode, and an electrolyte is filled between the transition metal oxide, for example, TiO 2 , the porous electrode, and the catalyst thin film electrode. Has a structure. In other words, the dye-sensitized solar cell uses an electrolyte as a hole transporting medium, and the electrolyte dependence of the dye-sensitized solar cell depends on the diffusion rate of the electrolyte, and the diffusion rate is a semi-solid or high Compared with the body type, the diffusion speed is high, so the photoelectric conversion efficiency is excellent.

도 1은 종래의 기술에 따른 액정 소자를 이용한 블라인드의 구성도이다.1 is a block diagram of a blind using a liquid crystal device according to the prior art.
도 1에 도시된 바와 같이, 종래의 기술에 따른 액정 소자를 이용한 블라인드는 다수의 가변성 유리(11, 12, 13)를 포함하는 패키지(10); 상기 가변성 유리의 각각의 투명/불투명 상태를 제어하는 구동부(20); 상기 구동부(20)에 제어신호를 출력하는 콘트롤러(30); 상기 콘트롤러(30)에 제어명령을 입력하는 키입력부(40); 외부의 조도를 검출하여 상기 콘트롤러(30)에 입력하는 조도검출부(50); 콘트롤러(30)에서의 작동에 필요한 프로그램과 제어 데이터를 저장하는 메모리(60); 리모콘(80)으로부터 입력되는 제어명령 신호를 수신하기 위한 신호 수신부(70)를 포함한다.As shown in FIG. 1, the blind using the liquid crystal device according to the related art includes a package 10 including a plurality of variable glasses 11, 12, and 13; A driver 20 for controlling each transparent / opaque state of the variable glass; A controller 30 for outputting a control signal to the driver 20; A key input unit 40 for inputting a control command to the controller 30; An illuminance detection unit 50 which detects an external illuminance and inputs it to the controller 30; A memory 60 for storing a program and control data necessary for operation in the controller 30; And a signal receiver 70 for receiving a control command signal input from the remote controller 80.
가변성 유리(11, 12, 13)는 내부에는 액정이 주입되고 전극이 돌출 형성된 액정판이 한 쌍의 글래스에 의하여 고정되어 있다. 이때, 액정판은 전극에 전원을 연결하지 않으면 액정 분자가 분산되어서 불투명 상태를 유지하고, 전극에 전원이 연결되면 액정분자가 정렬되면서 투명 상태가 된다.In the variable glass 11, 12, 13, the liquid crystal is inject | poured inside, and the liquid crystal plate in which the electrode protruded is fixed by a pair of glass. In this case, the liquid crystal plate maintains an opaque state by dispersing liquid crystal molecules when the power source is not connected to the electrode, and becomes transparent while the liquid crystal molecules are aligned when the power source is connected to the electrode.
상기 액정판은 한 쌍의 글래스에 의하여 보호되며 불투명상태에서는 불투명유리, 투명상태에서는 투명유리와 본질적으로 동일하게 작용한다.The liquid crystal plate is protected by a pair of glasses and functions essentially the same as opaque glass in the opaque state and transparent glass in the transparent state.

구체적으로, 염료감응 태양전지는 식물의 광합성 작용원리와 유사한 개념의 전지로서, 빛을 흡수하는 광감응성 염료(116), 이러한 염료(116)를 지지하는 나노 구조의 티타니아 전극(115), 전해질(117), 촉매 상대전극(113)으로 구성된 태양전지이다. 염료감응 태양전지는 기존의 실리콘 태양전지나 박막 태양전지와 같이 p형과 n형 반도체의 접합을 사용하지 않고, 전기화학적 원리에 의해 전기를 생산하므로, 이론 효율이 높고, 친환경적이어서 미래의 그린에너지로 가장 적합한 태양전지로 기대되고 있다.Specifically, the dye-sensitized solar cell is a cell having a concept similar to the principle of photosynthesis of plants, and includes a photosensitive dye 116 that absorbs light, a titania electrode 115 having a nanostructure supporting the dye 116, and an electrolyte ( 117), a solar cell composed of a catalyst counter electrode 113; Dye-sensitized solar cells do not use p-type and n-type semiconductor junctions like conventional silicon solar cells or thin-film solar cells, and produce electricity by electrochemical principles. It is expected to be the most suitable solar cell.
다시 말하면, 염료감응 태양전지는 크게 작동 전극(115), 전해질(117) 및 상대 전극(113)로 구성된다. 작동 전극(115)은 식물의 염록소와 같이 태양광 또는 실내광을 받아 전자를 높은 에너지 상태로 만들어 주는 염료들(116)이 높은 에너지를 쉽게 받아들이는 산화물 반도체 표면에 부착되어 있다.In other words, the dye-sensitized solar cell is largely composed of a working electrode 115, an electrolyte 117, and a counter electrode 113. The working electrode 115 is attached to the surface of the oxide semiconductor, where dyes 116, such as chlorophyll of plants, that receive sunlight or room light to bring electrons into a high energy state are easily absorbed.
따라서 외부의 빛이 염료(116)에 닿으면 염료(116)에서 전자기 에너지를 얻어 높은 에너지의 전자가 되고, 이를 나노 구조의 산화물 반도체(주로 TiO2가 이용됨)인 작동 전극(115)이 받아 외부로 전달한다. 이후, 높은 에너지의 전자는 외부회로를 타고 흐르면서 자신의 에너지를 소모하게 되고, 다시 상대 전극(113)에 도달하게 된다. 이때, 작동 전극(115)의 염료(116)에서 전자가 외부로 빠져 나갔기 때문에 전해질(117) 내부의 이온에서 한 개의 전자가 다시 염료(116)로 공급되고, 외부에서 상대 전극으로 돌아온 전자는 다시 전해질(117) 내부의 이온으로 전달됨으로써 에너지 전달 과정이 연속적으로 이루어지게 된다.Therefore, when external light comes into contact with the dye 116, the electromagnetic energy is obtained from the dye 116 to become electrons of high energy, which is received by the working electrode 115, which is a nanostructured oxide semiconductor (mostly TiO 2 is used). To pass. Thereafter, the high energy electrons consume their energy while flowing in an external circuit, and reach the counter electrode 113 again. At this time, since electrons escaped from the dye 116 of the working electrode 115 to the outside, one electron is again supplied to the dye 116 from the ions inside the electrolyte 117, and the electrons returned from the outside to the counter electrode are returned again. The energy transfer process is continuously performed by being transferred to the ions in the electrolyte 117.
이러한 과정들은 주로 작동 전극(115)과 전해질(117) 사이와 상대 전극(113)과 전해질(117) 사이에서 이루어지는 전기화학 반응에 따르므로, 전극과 전해질이 닿는 면적이 넓을수록 많은 반응이 빠르게 진행될 수 있다. 아울러 작동 전극(115)의 표면 면적이 넓을수록 많은 양의 염료가 붙어 있을 수 있기 때문에 생산할 수 있는 전력의 양이 증가하게 된다. 따라서 각각의 전극(113, 115) 소재로 나노 입자를 사용하며, 동일 부피에서 물질의 표면적이 극단적으로 증가하기 때문에 많은 양의 염료를 표면에 부착할 수 있고, 전극(113, 115)과 전해질(117) 사이의 전기화학 반응의 속도를 증가시킬 수 있다.These processes are mainly based on the electrochemical reaction between the working electrode 115 and the electrolyte 117 and between the counter electrode 113 and the electrolyte 117, so that the larger the area where the electrode and electrolyte are in contact, the faster the reaction. Can be. In addition, the larger the surface area of the working electrode 115, the greater the amount of dye that can be attached to the amount of power that can be produced is increased. Therefore, the nanoparticles are used as the material of each of the electrodes 113 and 115, and since the surface area of the material increases dramatically in the same volume, a large amount of dye can be attached to the surface, and the electrodes 113 and 115 and the electrolyte ( It is possible to increase the rate of the electrochemical reaction between 117).
