제1 전극(120)은 기판(110) 상에 형성되며, 광흡수저장층(160)의 전자이동에 관여한다. 제1 전극(120)은 기판(110)을 투과한 광이 광흡수저장층(160)에 도달되도록 투명한 전도성 금속산화물을 포함한다. The first electrode 120 is formed on the substrate 110 and participates in electron transfer of the light absorption and storage layer 160 . The first electrode 120 includes a transparent conductive metal oxide so that light transmitted through the substrate 110 reaches the light absorption and storage layer 160 .

It may include, and may include graphite (graphite) in the case of a negative electrode.

전해질(150)은 광흡수저장층(160)과 제2 전극(130) 사이에서 양이온이 이동할 수 있게 한다. 전해질은 공지의 액체전해질, 겔폴리머 전해질, 고체전해질 중 어느 하나로 구비될 수 있으며, 고체전해질의 경우, 세퍼레이터는 생략될 수 있다.

The light-scattering particles include a transparent material, scatter light that passes through the light absorption and storage layer 160 and reaches the electrolyte 150, and returns some of the scattered light to the light absorption and storage layer 160, thereby returning the solar cell to the solar cell. Efficiency of the battery-integrated device may be increased.
광흡수저장층(160)은 광을 흡수하여 홀전자쌍을 생성하여 도선을 통해 전자를 제2 전극(130)에 제공하며, 제2 전극(130)으로부터 세퍼레이터(140)을 통해 제공되는 양이온을 저장하거나 세퍼레이터(140)를 통해 제2 전극(130)에 양이온을 제공하는 기능을 수행한다. The light absorption storage layer 160 absorbs light to generate an unpaired electron pair, provides electrons to the second electrode 130 through a conducting wire, and stores positive ions provided from the second electrode 130 through the separator 140. Alternatively, it serves to provide positive ions to the second electrode 130 through the separator 140 .
일반적으로 태양전지의 경우, 발전능력은 있지만 저장능력이 없어서, 광충전에 의해 발생한 전력을 저장할 별도의 배터리가 필요하다. 본 발명의 경우, 광흡수저장층이 광을 흡수하여 광전효과를 일으킬 뿐만 아니라 양이온의 저장 및 방출을 통해 저장능력도 구비함으로써 별도의 배터리가 필요하지 않게 된다.In general, in the case of a solar cell, a separate battery is required to store the power generated by photocharging because it has power generation capability but no storage capability. In the case of the present invention, the light absorption and storage layer not only absorbs light to cause a photoelectric effect, but also has a storage capability through storage and release of positive ions, so that a separate battery is not required.
도 2의 (a)를 참조하면, 광흡수저장층(160)은 광을 흡수하여 홀전자쌍을 생성하고, 전자를 도선을 통해 제2 전극(130)에 제공한다. 이와 동시에 광흡수저장층(160)은 리튬양이온(Li+)을 방출하고 방출된 리튬양이온(Li+)을 전해질(150)을 통해 제2 전극(130)에 제공한다. 제2 전극(130)에 제공된 리튬양이온(Li+)은 리튬(Li)으로 환원된다. 도 2에서 양이온이 리튬양이온(Li+)으로 설명되었지만, 이에 제한되는 것은 아니다.Referring to (a) of FIG. 2 , the light absorption and storage layer 160 absorbs light to generate an unpaired electron pair and provides electrons to the second electrode 130 through a wire. At the same time, the light absorption storage layer 160 emits lithium cations (Li+) and supplies the released lithium cations (Li+) to the second electrode 130 through the electrolyte 150. Lithium cations (Li+) supplied to the second electrode 130 are reduced to lithium (Li). In FIG. 2, the cation is described as lithium cation (Li+), but is not limited thereto.
도 2의 (b)를 참조하면, 광흡수저장층(160)은, 방전시, 제1 전극(120)에 홀을 전달하고, 제2 전극(130)으로부터 제1 전극(120)으로 도선을 통해 제공되는 전자에 결합한다. 또한 광흡수저장층(160)은 제2 전극(130)으로부터 방출되어 전해질(150)을 통과해온 리튬양이온(Li+)을 흡수하여 저장한다.

도 3a는 도 1a에 도시된 광흡수저장층의 (A')2(A)n-1BnX3n+1 구조를 설명하기 위한 도면이다. 도 3b는 도 1a에 도시된 광흡수저장층의 ANA'1-NBX3 구조를 설명하기 위한 도면이다.FIG. 3A is a view for explaining the (A′) 2 (A) n−1 B n X 3n+1 structure of the light absorption and storage layer shown in FIG. 1A. FIG. 3B is a view for explaining the A N A ′ 1-N BX 3 structure of the light absorption and storage layer shown in FIG. 1A.
도 3a를 참조하면, 광흡수저장층(160)이 층상구조인 경우, 세퍼레이터(140)를 통과한 양이온은 광전극(130)의 층간에서 저장/방출될 수 있다. 광흡수저장층(160)이 3차원 구조인 페로브스카이트 소재를 포함하는 경우, 페로브스카이트 소재를 제1 전극(120)에 층상구조로 배열하여 다시 2차원 구조를 중첩하여 형성할 수 있다. Referring to FIG. 3A , when the light absorption and storage layer 160 has a layered structure, positive ions passing through the separator 140 may be stored/released between layers of the photoelectrode 130 . When the light absorption and storage layer 160 includes a three-dimensional perovskite material, the perovskite material can be formed by arranging the first electrode 120 in a layered structure and overlapping the two-dimensional structure again. there is.
한편, 페로브스카이트는 태양전지에 널리 사용되고 있으나, 에너지 저장능력이 없는 태양전지의 특성을 고려해 볼 때, 태양전지에 사용되는 페로브스카이트는 리튬양이온의 저장과는 전혀 관련이 없다. On the other hand, perovskite is widely used in solar cells, but considering the characteristics of solar cells without energy storage capability, perovskite used in solar cells has nothing to do with the storage of lithium cations.
도 3a 및 도 3b를 참조하면, 본 발명에서는, 페로브스카이트 소재 ABX3에서 A의 일부 또는 전부가 카르보닐화합물로 치환된 도 3a에 도시된 ANA'1-NBX3 (여기서 N은 0<N<1 인 실수)의 구조를 갖거나 또는 도 3b와 같은 (A')2(A)n-1BnX3n+1(여기서 n은 정수)구조를 갖는다. 3a and 3b, in the present invention, in the perovskite material ABX 3 , some or all of A is substituted with a carbonyl compound A N A' 1-N BX 3 shown in FIG. is a real number of 0<N<1) or has a structure of (A′) 2 (A) n−1 B n X 3n+1 (where n is an integer) as shown in FIG. 3B.
A'인 카르보닐화합물은 탄소와 산소의 이중결합을 포함하며, 카르보닐의 특성상 산소 부분이 Li양이온과 잘 결합될 수 있다. 따라서 페르보스카이트 구조에서 A의 일부 또는 전부가 카르보닐화합물 A'로 치환되는 경우, 리튬양이온의 저장효율을 카르보닐화합물이 없는 경우에 비해 더욱 증가시킬 수 있다. The carbonyl compound of A' includes a double bond between carbon and oxygen, and due to the nature of carbonyl, the oxygen moiety can be well bonded to Li cations. Therefore, when part or all of A in the perovskite structure is substituted with the carbonyl compound A', the storage efficiency of lithium cations can be further increased compared to the case where the carbonyl compound is not present.
3D구조를 이루는 페로브스카이트에서 A의 일부 또는 전부를 카르보닐화합물 A'로 대체하는 경우, 페로브스카이트는 유사(Quasi) 2D구조 또는 2D구조를 갖을 수 있다. In the case of replacing part or all of A in perovskite having a 3D structure with carbonyl compound A', the perovskite may have a quasi 2D structure or 2D structure.
페로브스카이트 구조에서 A가 카르보닐 화합물 A'로 전부 치환되는 경우, 2D구조의 페로브스카이트가 될 확률이 높아진다. 그리고 페로브스카이트 구조에서 A의 일부가 카르보닐화합물 A'로 대체된 유사(Quasi-) 2D구조의 페로브스카이트가 될 확률이 높아진다.When all of A in the perovskite structure is substituted with the carbonyl compound A', the probability of becoming a 2D perovskite increases. And in the perovskite structure, a part of A is replaced with carbonyl compound A', and the probability of becoming a quasi- 2D perovskite structure increases.
2D구조의 페로브스카이트는, Quasi-2D구조 및 3D구조에 비해 전자이동도가 감소하여 태양전지 성능이 떨어질 수 있으나, 금속양이온을 흡수하기 위한 카르보닐화합물 A'이 다수 포함되어 있기 때문에 Quasi-2D구조 및 3D구조에 비해 배터리 성능은 향상될 수 있다. 2D structured perovskite may have reduced electron mobility compared to quasi-2D and 3D structures, resulting in poor solar cell performance. Compared to the 2D structure and the 3D structure, battery performance can be improved.
즉, 태양전지 성능면에서 페로브스카이트 구조는, 2D구조, Quasi-2D구조, 3D구조로 갈수로 향상된다. 한편 배터리 성능면에서 페로브스카이트 구조는 3D구조, Quasi-2D구조, 2D구조로 갈수록 향상된다.In other words, in terms of solar cell performance, the perovskite structure is improved in terms of 2D structure, Quasi-2D structure, and 3D structure. On the other hand, in terms of battery performance, the perovskite structure is gradually improved in 3D structure, Quasi-2D structure, and 2D structure.
