Sang Won Lee,Seongtak Kim,Soohyun Bae,Kyung-Jin Cho,Taewon Chung,Laura E. Mundt,Seunghun Lee,Seunghun Lee,Sungeun Park,Sungeun Park,Hyomin Park,Martin C. Schubert,Stefan W. Glunz,Stefan W. Glunz,Yohan Ko,Yongseok Jun,Yoonmook Kang,Hae-Seok Lee,Donghwan Kim +18 more
TL;DR: The degradation of perovskite solar cells in the presence of UV light alone was examined, and during exposure to consecutive UV light, the diminished short circuit current density (Jsc) and EQE continuously restored.
Journal ArticleDOI
Investigation of Thermally Induced Degradation in CH 3 NH 3 PbI 3 Perovskite Solar Cells using In-situ Synchrotron Radiation Analysis
Nam Kim,Young Hwan Min,Seokhwan Noh,Eunkyung Cho,Gitaeg Jeong,Minho Joo,Seh Won Ahn,Jeong Soo Lee,Seongtak Kim,Kyuwook Ihm,Hyungju Ahn,Yoonmook Kang,Hae-Seok Lee,Donghwan Kim +13 more
TL;DR: This study confirms that the surface structure of MAPbI3 perovskite film changes to an intermediate phase and decomposes to CH3I, NH3, and PbI2 after both a short and a long exposure to heat stress at 100 °C.
Journal ArticleDOI
Hybrid solar cells with vertically aligned CdTe nanorods and a conjugated polymer
TL;DR: In this paper, vertical aligned CdTe nanorods were fabricated by electrodeposition and were applied for the active layer of solar cells after being combined with poly(3-octylthiophene) (P3OT), a conjugated polymer.
Journal ArticleDOI
Electric-Field-Induced Degradation of Methylammonium Lead Iodide Perovskite Solar Cells.
Soohyun Bae,Seongtak Kim,Sang Won Lee,Kyung-Jin Cho,Sungeun Park,Sungeun Park,Seunghun Lee,Seunghun Lee,Yoonmook Kang,Hae-Seok Lee,Donghwan Kim +10 more
TL;DR: It is demonstrated that perovskite solar cells are stable under an electric field up to the operating voltage, and Ion migration is confirmed using the temperature-dependent dark current decay.
Journal ArticleDOI
Relationship between ion migration and interfacial degradation of CH3NH3PbI3 perovskite solar cells under thermal conditions.
Seongtak Kim,Soohyun Bae,Sang Won Lee,Kyung-Jin Cho,Kyung Dong Lee,Hyunho Kim,Sungeun Park,Guhan Kwon,Seh Won Ahn,Heon Min Lee,Yoonmook Kang,Hae-Seok Lee,Donghwan Kim +12 more
TL;DR: It was confirmed that, at high temperatures (85 °C), I− and CH3 NH3+ (MA+) diffused into the spiro-OMeTAD layer in the form of CH3NH3I (MAI).
