리드 부재를 갖는 염료감응 태양전지Dye-Sensitized Solar Cell with Lead Member
본 발명은 염료감응 태양전지에 관한 것으로, 상세하게는 모듈 또는 단위셀로부터 전기를 인출하는 리드 부재를 갖는 염료감응 태양전지에 관한 것이다.The present invention relates to a dye-sensitized solar cell, and more particularly, to a dye-sensitized solar cell having a lead member for drawing electricity from a module or a unit cell.
1991년도 스위스 로잔 연방공과대학(EPFL)의 마이클 그라첼(Michael Gratzel) 연구팀이 염료감응 나노입자 산화티타늄 태양전지를 개발한 이후, 이 분야에서 많은 연구가 진행되어 왔다.Since Michael Gratzel's team at the Swiss Federal Institute of Technology (EPFL) in 1991 developed a dye-sensitized nanoparticle titanium oxide solar cell, much work has been done in this area.
염료감응 태양전지는 기존의 실리콘계 태양전지에 비해 제조 단가가 낮아 기존의 비정질 실리콘 태양전지를 대체할 수 있을 것으로 기대되고 있다. 염료감응 태양전지는, 실리콘 태양전지와 달리, 가시광선을 흡수하여 전자-홀 쌍을 생성하는 염료분자와, 생성된 전자를 전달하는 전이금속 산화물을 주된 구성 요소로 하는, 광전기-화학적 태양전지이다.Dye-sensitized solar cells are expected to be able to replace conventional amorphous silicon solar cells due to lower manufacturing costs compared to conventional silicon-based solar cells. Dye-sensitized solar cells, unlike silicon solar cells, are photoelectro-chemical solar cells whose main components are dye molecules that absorb visible light to form electron-hole pairs, and transition metal oxides that transfer the generated electrons. .
일반적인 염료감응 태양전지의 단위셀의 구조는, 전면 투명기판, 후면 투명기판, 그리고 전면/후면 투명기판의 각 표면에 형성되는 도전성 투명 전극을 기본 구성요소로 한다. 전면 투명기판의 도전성 투명 전극에는 전이금속 산화물, 예를들어 TiO2 다공질층이 형성된다. 나노 입자 다공질 TiO2의 표면에는 염료가 흡착되어 있다. 후면 투명기판의 도전성 투명 전극에는 촉매전극이 형성된다. 그리고, TiO2 다공질층과 촉매전극 사이에는 전해질이 채워진다.The structure of a unit cell of a general dye-sensitized solar cell is based on a conductive transparent electrode formed on each surface of the front transparent substrate, the rear transparent substrate, and the front / rear transparent substrate. In the conductive transparent electrode of the front transparent substrate, a transition metal oxide, for example, a TiO 2 porous layer is formed. The surface of the nanoparticles, the porous TiO 2 has the dye is adsorbed. A catalytic electrode is formed on the conductive transparent electrode of the rear transparent substrate. An electrolyte is filled between the TiO 2 porous layer and the catalyst electrode.
염료감응 태양전지의 전기 발생 원리는, 염료가 빛을 흡수하면 염료 내부의 전자가 여기되어 TiO2 다공질층으로 이동하여 외부 전극까지 도달함에 따라 한 극을 이루고, 염료에서 전자가 빠져나간 자리는 전해질 속에 있는 요오드 이온의 산화 작용에 의해 요오드의 전자가 이동하여 채워진다. 요오드 이온은 촉매전극 쪽으로 이동하여 촉매전극 표면에서 환원 작용에 의해 전자를 다시 공급받는다. 이때, 전압은 TiO2 의 전도대 최하단의 에너지 준위와 촉매전극 표면에서 요오드 이온의 환원 준위 차이로 결정된다.The principle of electricity generation of dye-sensitized solar cells is that when the dye absorbs light, the electrons inside the dye are excited to move to the TiO 2 porous layer and reach the external electrode, and the electron escapes from the dye. By oxidizing iodine ions in the inside, electrons of iodine move and are filled. Iodine ions move toward the catalyst electrode and are supplied with electrons again by a reducing action on the surface of the catalyst electrode. In this case, the voltage is determined by the difference between the energy level at the bottom of the conduction band of TiO 2 and the reduction level of iodine ions at the surface of the catalyst electrode.
그런데, 염료감응 태양전지는 1 ㎠ 이하의 작은 면적에서는 효율이 높으나 대면적으로 제조하면 기판과 소재의 저항 때문에 효율이 급격히 떨어진다. 이 때문에, 대면적 모듈로 제조하기 위하여 인접 단위셀들을 전기적으로 연결하게 되고, 최종적으로 다수의 단위셀들로 구성된 서브 모듈에서 생성된 전기를 외부로 인출하게 된다.However, dye-sensitized solar cells have high efficiency at a small area of 1 cm 2 or less, but when manufactured in large areas, the efficiency decreases rapidly due to the resistance of the substrate and the material. For this reason, in order to manufacture a large area module, adjacent unit cells are electrically connected, and finally, electricity generated in a sub module including a plurality of unit cells is drawn out to the outside.

This problem can be solved by adjusting the number of threads of the female threads 512 and 552 and the number of threads of the male threads 522 and 562.
도3b는 도3a와 유사하고, 다만 결합 방식이 나사 방식이 아닌 돌기 방식을 취하고 있다는 점에서만 다르므로, 당업자라면 도2b의 설명 및 도3a의 설명을 통해 도3b의 기술적 특징을 충분히 이해할 수 있을 것이다. 따라서, 자세한 설명은 생략한다.FIG. 3B is similar to FIG. 3A, except that the coupling method is a projection method rather than a screw method, so that those skilled in the art can fully understand the technical features of FIG. 3B through the description of FIG. 2B and the description of FIG. 3A. will be. Therefore, detailed description is omitted.
