본 발명은 벌크이종접합 구조의 태양전지용 활성층에 관한 것으로, 보다 상세하게는 정공수송물질(HTM)과 전자수송물질(ETM)의 벌크이종접합구조에 페로브스카이트 입자가 분포되어 효율이 개선된 태양전지용 활성층에 관한 것이다.The present invention relates to an active layer for a solar cell having a bulk heterojunction structure, and more particularly, perovskite particles are distributed in a bulk heterojunction structure of a hole transport material (HTM) and an electron transport material (ETM), thereby improving efficiency. It relates to an active layer for solar cells.

Si 태양전지의 경우 기존 화석연료나 원자력발전에 비해 여전히 발전단가가 높아 새로운 구조나 물질의 차세대 태양전지에 대한 연구가 관심을 받고 있다. 대표적으로 유기태양전지, 페로브스카이트 태양전지, 박막형 태양전지 등 다양한 차세대 태양전지가 많은 연구가 되고 있다. 페로브스카이트 물질(perovskite material)은 AMX3 구조체(A, M은 양이온, X는 음이온)로서 이온결정이면서 직접형 띠간격(direct band gap)을 갖는 유/무기 복합물질이다In the case of Si solar cells, the cost of power generation is still higher than that of conventional fossil fuels or nuclear power generation, so research on next-generation solar cells with new structures or materials is drawing attention. Representatively, various next-generation solar cells such as organic solar cells, perovskite solar cells, and thin-film solar cells are being studied. The perovskite material is an AMX3 structure (A, M is a cation, X is an anion), which is an organic/inorganic composite material that is ionic crystal and has a direct band gap.

그 중에서도 페로브스카이트 태양전지(perovskite solar cell)는 높은 광 흡수도와 긴 확산거리로 인해 기존 Si 태양전지를 대체할 만큼의 효율을 보여주고 있으며, flexible 하며 매우 값싼 재료를 사용하기 때문에 실용화 측면 폭발적인 관심을 받고 있다. 페로브스카이트 태양전지의 가장 큰 단점은 내구성이었지만, 지속적으로 개선되고 있으며 대변적의 높은 효율을 개발하기 위해 많은 연구가 되고 있다. 일반적인 페로브스카이트 태양전지는 "투명전극/정공수송층/페로브스카이트/전자수송층/금속전극"의 순서로 적층된 구조를 갖는다.Among them, perovskite solar cells show high light absorption and long diffusion distances, so they are efficient enough to replace existing Si solar cells. They are flexible and use very inexpensive materials. I am getting attention. The biggest drawback of perovskite solar cells was durability, but it is continuously improving, and a lot of research is being conducted to develop high efficiency of large volume. A typical perovskite solar cell has a structure stacked in the order of "transparent electrode/hole transport layer/perovskite/electron transport layer/metal electrode".

페로브스카이트 태양전지의 경우 다양한 구조로 연구가 진행되고 있는데 초기에는 염료감응형 태양전지(dye-sensitized solar cell)와 같은 형태로 TiO2 나노입자(nanoparticle)에 양자점(quantum dot) 형태로 붙여 매우 낮은 효율을 보고하였다. 하지만, 성균관대학교에서 고체 형태의 페로브스카이트를 개발함에 따라 급격한 효율 개선이 이루어지고 있다. 고체 형태의 기존 페로브스카이트 구조는 도 1과 같다. 도 1의 TiO2 나노입자의 경우, 페로브스카이트에서 만들어진 전하를 추출하기 위해 사용되는데 접촉 면적을 넓히기 위해 TiO2 나노입자를 3차원(3D)구조의 mesoporous형태로 사용하여 전하 추출효율을 높여 고효율을 달성하였다. 하지만, 도 2의 TEM 이미지와 같이 여전히 음극쪽에만 3D구조를 갖는 형태로 접촉 면적이 매우 적다. 또한, 나노입자를 3D구조로 mesoporous형태로 만들기 위해서 까다로운 공정 및 높은 온도의 열처리가 필요하기 때문에 새로운 공정 방법이 연구 개발 되어야한다. 따라서 최근에는 도 3과 같이 TiO2, SnO2, 그리고 ZnO 등의 colloidal nanoparticles을 낮은 온도에서 solution 방식으로 제작하여 planer형태의 구조가 많은 연구가 되고 있다. 그러나 더욱 접촉 면적이 적어 전하를 추출하는데 한계가 있다.In the case of perovskite solar cells, research is being conducted in various structures, but at the beginning, they are attached to TiO 2 nanoparticles in the form of quantum dots in the same form as a dye-sensitized solar cell. It reported very low efficiency. However, as Sungkyunkwan University develops a solid form of perovskite, there is a rapid improvement in efficiency. The existing perovskite structure in solid form is shown in FIG. 1. In the case of the TiO 2 nanoparticles of FIG. 1, it is used to extract the electric charge made from the perovskite. In order to increase the contact area, the TiO 2 nanoparticles are used in a mesoporous form of a three-dimensional (3D) structure to increase the charge extraction efficiency. High efficiency was achieved. However, as in the TEM image of FIG. 2, the contact area is very small since the 3D structure is still formed only on the cathode side. In addition, in order to make nanoparticles mesoporous in a 3D structure, a difficult process and high temperature heat treatment are required, so a new process method must be researched and developed. Therefore, recently, as shown in FIG. 3, colloidal nanoparticles such as TiO 2 , SnO 2 , and ZnO are fabricated in a solution method at a low temperature, and thus, many studies have been conducted on a planer structure. However, since the contact area is smaller, there is a limit to extracting electric charges.

이러한 문제를 해결하기 위해 페로브스카이트 활성층(active layer) 합성시 TiO2 나노입자를 삽입하는 등 다양한 연구가 진행되고 있으나 여전히 효율이 낮은 문제가 있다.In order to solve this problem, various studies such as inserting TiO 2 nanoparticles when synthesizing a perovskite active layer have been conducted, but there is still a problem of low efficiency.
