Soo-Jin Moon,Jun-Ho Yum,Robin Humphry-Baker,Karl Martin Karlsson,Daniel P. Hagberg,Tannia Marinado,Anders Hagfeldt,Licheng Sun,Michael Grätzel,Khaja Nazeeruddin +9 more
TL;DR: In this paper, an organic sensitizers comprising of donor, electron-conducting, and anchoring groups are designed and developed for dye-sensitized solar cell applications, which exhibits a short circuit photocurrent density of 9.64 mA/cm2, an open circuit voltage of 798 mV, and a fill factor of 0.57.
Journal ArticleDOI
Impact of a Mesoporous Titania–Perovskite Interface on the Performance of Hybrid Organic–Inorganic Perovskite Solar Cells
Mojtaba Abdi-Jalebi,M. Ibrahim Dar,Aditya Sadhanala,Satyaprasad P. Senanayak,Fabrizio Giordano,Shaik M. Zakeeruddin,Michael Grätzel,Richard H. Friend +7 more
TL;DR: Modification of the mesoporous TiO2 film by TiCl4 treatment substantially reduced the surface traps, which led to an order of magnitude enhancement in the bulk electron mobility and corresponding decrease in the transport activation energy within a device.
Journal ArticleDOI
High-efficiency and stable quasi-solid-state dye-sensitized solar cell based on low molecular mass organogelator electrolyte
Li Tao,Zhipeng Huo,Yong Ding,Yi Li,Songyuan Dai,Songyuan Dai,Lu Wang,Jun Zhu,Xu Pan,Bing Zhang,Jianxi Yao,Mohammad Khaja Nazeeruddin,Michael Grätzel +12 more
TL;DR: In this article, a quasi-solid-state DSSC (QS-DSSC) based on a low molecular mass organogelator (LMOG) is achieved using N,N′-1,5-pentanediylbis-dodecanamide as a LMOG in conjunction with a TiO2 photoanode of sub-microspheres sensitized with a highabsorptivity Ru complex.
Journal ArticleDOI
Efficient stable graphene-based perovskite solar cells with high flexibility in device assembling via modular architecture design
Chunyang Zhang,Shi Wang,Hong Zhang,Yulin Feng,Wenming Tian,Ying Yan,Jiming Bian,Yuchen Wang,Shengye Jin,Shaik M. Zakeeruddin,Michael Grätzel,Yantao Shi +11 more
TL;DR: In this paper, a modular perovskite solar cells (C-PSCs) design using a carbon back electrode, whose sheet resistance and thickness were greatly reduced by covering it with another carbon-coated FTO glass that was applied under pressure.
Journal ArticleDOI
The Role of π Bridges in High-Efficiency DSCs Based on Unsymmetrical Squaraines
Jared H. Delcamp,Yanrong Shi,Jun-Ho Yum,Tissa Sajoto,Elisa Dell'Orto,Stephen Barlow,Mohammad Khaja Nazeeruddin,Seth R. Marder,Michael Grätzel +8 more
TL;DR: The dye that incorporates a 4,4-di-n-hexyl-cyclopentadithiophene group that is directly attached onto the π bridge, JD10, exhibits the highest power conversion efficiency in a DSC; this result is attributed, in part, to the deaggregative properties that are associated with the gem-di,n- hexyl substituents, which extend above and below the ρ-conjugated dye plane.
