Thick TiO2-Based Top Electron Transport Layer on Perovskite for Highly Efficient and Stable Solar Cells
Yong Zhao,Hong Zhang,Xingang Ren,Hugh L. Zhu,Zhanfeng Huang,Fei Ye,Dan Ouyang,Kok Wai Cheah,Alex K.-Y. Jen,Alex K.-Y. Jen,Wallace C. H. Choy +10 more
TL;DR: In this paper, a fullerene-decorated TiO2 electron transport layer (ETL) was constructed on top of a perovskite film through a simple room-temperature solution process.
Journal ArticleDOI
n-Doping of thermally polymerizable fullerenes as an electron transporting layer for inverted polymer solar cells
Namchul Cho,Hin-Lap Yip,Steven K. Hau,Kung-Shih Chen,Tae-Wook Kim,Joshua A. Davies,David F. Zeigler,Alex K.-Y. Jen +7 more
TL;DR: In this paper, a novel [6,6]-phenyl-C61-butyric acid methyl styryl ester (PCBM-S) was synthesized and employed as an electron transporting interfacial layer for bulk heterojunction polymer solar cells with an inverted device configuration.
Journal ArticleDOI
Spiro-Phenylpyrazole-9,9′-Thioxanthene Analogues as Hole-Transporting Materials for Efficient Planar Perovskite Solar Cells
TL;DR: In this article, a series of hole-transporting materials (HTMs) with small molecular weight are designed, which are constructed on a spiro core involving phenylpyrazole and a second heteroaromatics, i.e., xanthene (O atom), thioxanthene(S atom), and acridine (N atom).
Journal ArticleDOI
Ketene dithioacetal as a π-electron donor in second-order nonlinear optical chromophores
TL;DR: In this paper, it was shown experimentally that the ketene dithioacetal group is very effective as an electron-donating group in the design and synthesis of thermally stable and efficient second-order nonlinear optical chromophores.
Journal ArticleDOI
Surface-Initiated Synthesis of Poly(3-methylthiophene) from Indium Tin Oxide and its Electrochemical Properties
Natalia Doubina,Judith L. Jenkins,Sergio A. Paniagua,Katherine A. Mazzio,Gordon A. MacDonald,Alex K.-Y. Jen,Neal R. Armstrong,Seth R. Marder,Christine K. Luscombe +8 more
TL;DR: This work represents the first time that polymer thickness has been controlled in a surface initiated K CTP reaction, highlighting the utility of KCTP in achieving controlled polymerizations.
