Charge Accumulation, Recombination, and Their Associated Time Scale in Efficient (GUA) x (MA)1-x PbI3-Based Perovskite Solar Cells.
Daniel Prochowicz,Daniel Prochowicz,Mohammad Mahdi Tavakoli,Mohammad Mahdi Tavakoli,Anwar Q. Alanazi,Suverna Trivedi,Hadi Tavakoli Dastjerdi,Shaik M. Zakeeruddin,Michael Grätzel,Pankaj Yadav +9 more
TL;DR: Electrochemical impedance spectroscopy results prove that incorporation of GUA forms electronic and ionic accumulation regions at the interface of the electron transporting layer and perovskite absorber layer are associated with the enhanced surface charge capacitance and photovoltage.
Journal ArticleDOI
Preparation of SrTiO3 by sol–gel techniques for the photoinduced production of H2 and surface peroxides from water
TL;DR: In this paper, a method of preparing SrTiO3 by the citrate route and sol-gel freeze-drying technique is presented, and the influence of the preparative conditions on the catalysed H evolution has been explored.
Journal ArticleDOI
High absorption coefficient cyclopentadithiophene donor-free dyes for liquid and solid-state dye-sensitized solar cells
Yue Hu,Antonio Abate,Yiming Cao,Aruna Ivaturi,Shaik M. Zakeeruddin,Michael Grätzel,Neil Robertson +6 more
TL;DR: A series of donor-free dyes featuring moieties of oligo(4,4-dihexyl-4H-cyclopenta[1,2-b:5,4b′]dithiophene) (CPDT-3) functionalized with cyanoacrylic end groups for mesoscopic titania solar cells based on I-/I3- or Co(II)/Co(III) redox couple and spiro-OMeTAD hole transporter were reported in this paper.
Journal ArticleDOI
SnS Quantum Dots as Hole Transporter of Perovskite Solar Cells
Yang Li,Zaiwei Wang,Dan Ren,Yuhang Liu,Aibin Zheng,Shaik M. Zakeeruddin,Xiandui Dong,Anders Hagfeldt,Michael Grätzel,Peng Wang +9 more
TL;DR: In this paper, the authors introduced SnS quantum dots (QDs) as a new inorganic hole transporting material (HTM) to perovskite solar cells and obtained a power conversion efficiency (PCE) of 13.7% compared with the 2,2′, 7,7,7′tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD)-based control devic...
