Abstract
Description
본 발명은 염료감응태양전지(dye-sensitized solar cell, DSSC)에 사용되는 염료 및 이의 제조방법에 관한 것이다.
The present invention relates to a dye used in a dye-sensitized solar cell (DSSC) and a method for producing the same.
1991년도 마이클 그라첼(Michael Gratzel) 연구팀에 의해 염료감응 나노입자 산화티타늄 태양전지가 개발된 이후 이 분야에 관한 많은 연구가 진행되고 있다. 염료감응태양전지는 기존의 실리콘계 태양전지에 비해 효율이 높고 제조단가가 현저히 낮기 때문에 기존의 비정질 실리콘 태양전지를 대체할 수 있는 가능성을 가지고 있으며, 실리콘 태양전지와 달리 염료감응태양전지는 가시광선을 흡수하여 전자-홀(hole) 쌍을 생성할 수 있는 염료분자와, 생성된 전자를 전달하는 전이금속 산화물을 주 구성 재료로 하는 광전기화학적 태양전지이다.Since the development of dye-sensitized nanoparticle titanium oxide solar cells in 1991 by Michael Gratzel's team, much research has been done in this area. Dye-sensitized solar cells have the potential to replace conventional amorphous silicon solar cells because of their higher efficiency and lower manufacturing costs than conventional silicon-based solar cells. It is a photoelectrochemical solar cell whose main constituent material is a dye molecule capable of absorbing and generating electron-hole pairs, and a transition metal oxide for transferring generated electrons.
염료감응태양전지에 사용되는 염료로서 높은 광전기 전환효율을 나타내는 루테늄 금속 착체가 널리 사용되어 왔는데, 이 루테늄 금속 착체는 가격이 너무 비싸다는 단점이 있었다.As a dye used in dye-sensitized solar cells, ruthenium metal complexes having high photovoltaic conversion efficiency have been widely used, but this ruthenium metal complex has a disadvantage of being too expensive.
최근, 흡광효율, 산화환원 반응 안정성 및 분자내 전하-전달(charge-transfer, CT)계 흡수의 측면에서 우수한 물성을 나타내는, 금속을 함유하지 않은 유기염료가, 고가의 루테늄 금속 착체를 대체할 수 있는 태양전지용 염료로서 사용될 수 있음이 발견되어, 금속이 결여된 유기염료에 대한 연구가 중점적으로 이루어지고 있다.Recently, metal-free organic dyes, which exhibit excellent physical properties in terms of light absorption efficiency, redox reaction stability, and intramolecular charge-transfer (CT) absorption, can replace expensive ruthenium metal complexes. It has been found that it can be used as a dye for solar cells, and research on organic dyes lacking metals has been focused on.
유기염료는 일반적으로 π-결합 유닛에 의해 연결되는 전자 공여체(electron donor)-전자 수용체(electron acceptor) 잔기의 구조를 갖는다. 대부분의 유기염료에서, 아민 유도체가 전자 공여체의 역할을 하고, 2-시아노아크릴산 또는 로다닌 잔기가 전자 수용체의 역할을 하며, 이 두 부위는 메타인 유닛 또는 티오펜 체인과 같은 π-결합 시스템에 의해 연결된다.Organic dyes generally have a structure of electron donor-electron acceptor residues linked by π-binding units. In most organic dyes, amine derivatives act as electron donors, 2-cyanoacrylic acid or rhodanine residues act as electron acceptors, and these two sites are π-binding systems such as metaine units or thiophene chains. Is connected by.
그러나, 이제까지 알려진 대부분의 유기염료는 루테늄 금속 착체 염료에 비해 낮은 변환효율과 낮은 구동 안정성을 나타내므로, 이러한 전자 공여체와 수용체의 종류 또는 π-결합 길이를 변화시킴으로써, 기존의 유기염료 화합물들에 비해 향상된 몰흡광계수를 가지며 높은 광전기 변환효율을 나타내는 새로운 염료를 개발하려는 노력이 지속되고 있는 실정이다.However, most of the organic dyes known so far have lower conversion efficiency and lower driving stability than ruthenium metal complex dyes. Thus, by changing the type or the π-bond length of these electron donors and acceptors, Efforts have been made to develop new dyes having an improved molar absorption coefficient and showing high photoelectric conversion efficiency.
또한 염료감응태양전지에 사용되는 전해질은 일반적으로 Iodide/Triiodide의 레독스 시스템을 이용하고 있다. 그러나 이 시스템은 금속에 대한 부식성이 있어 염료감응태양전지의 내구성을 떨어뜨리며, 또한 레독스 전위차가 작은 것이 문제점으로 대두되어 새로운 전해질에 대한 연구가 꾸준히 진행되고 있다.In addition, electrolytes used in dye-sensitized solar cells generally use the redox system of Iodide / Triiodide. However, this system is corrosive to metals, which reduces the durability of dye-sensitized solar cells, and the small redox potential difference is a problem, and research on new electrolytes is ongoing.
따라서, 본 발명은 종래의 염료보다 향상된 몰흡광계수, Jsc(단회로 광전류 밀도) 및 광전기 변환효율을 나타내며, 특히 코발트계 전해질과 병행사용하여 태양전지의 효율을 크게 향상시킬 수 있는 유기염료 및 이의 제조방법을 제공하는 것을 목적으로 한다.Therefore, the present invention exhibits an improved molar absorption coefficient, J sc (single circuit photocurrent density) and photoelectric conversion efficiency than conventional dyes, and in particular, organic dyes that can greatly improve the efficiency of solar cells using cobalt based electrolytes and It is an object to provide a method for producing the same.

또한 본 발명은 기존의 염료감응태양전지보다 얇은 박막으로의 제조를 가능하게 하고, 금속에 대한 부식성이 적어 염료감응태양전지의 내구성을 향상시킬 수 있으며, 특히 레독스 전위차가 커 염료감응태양전지의 효율을 크게 향상시킬 수 있는 새로운 전해질 시스템 및 이를 포함하는 염료감응태양전지를 제공하는 것을 목적으로 한다.
In addition, the present invention enables the manufacture of a thin film than the conventional dye-sensitized solar cell, and the corrosion resistance to the metal can be improved to improve the durability of the dye-sensitized solar cell, especially the redox potential difference is large It is an object of the present invention to provide a new electrolyte system and a dye-sensitized solar cell including the same, which can greatly improve the efficiency.
