Journal ArticleDOI
Ultrahydrophobic 3D/2D fluoroarene bilayer-based water-resistant perovskite solar cells with efficiencies exceeding 22.
Yuhang Liu,Seckin Akin,Seckin Akin,Linfeng Pan,Ryusuke Uchida,Ryusuke Uchida,Neha Arora,Jovana V. Milić,Alexander Hinderhofer,Frank Schreiber,Alexander R. Uhl,Shaik M. Zakeeruddin,Anders Hagfeldt,M. Ibrahim Dar,Michael Grätzel +14 more
TL;DR: This new approach provides water- and heat-resistant operationally stable PSCs with a record-level PCE, and enhances interfacial hole extraction, suppressing nonradiative carrier recombination and enabling a power conversion efficiency (PCE) >22%, the highest reported for 3D/2D architectures.
Journal ArticleDOI
Boosting the Efficiency of Perovskite Solar Cells with CsBr-Modified Mesoporous TiO2 Beads as Electron-Selective Contact
Ji-Youn Seo,Ryusuke Uchida,Hui-Seon Kim,Yasemin Saygili,Jingshan Luo,Christopher J Moore,Julie Kerrod,Anthony Wagstaff,Mike Eklund,Robert Mcintyre,Norman Pellet,Shaik M. Zakeeruddin,Anders Hagfeldt,Michael Grätzel +13 more
TL;DR: In this article, a mesoscopic architecture as electron-selective contact for perovskite solar cells is introduced, where 40 nm sized TiO2 beads endowed with mesopores of a few nanometer diameters are used to achieve a very high fill factor of close to 80% a VOC of 1.14 V and a PCE up to 21% with negligible hysteresis.
Journal ArticleDOI
Low‐Cost and Highly Efficient Carbon‐Based Perovskite Solar Cells Exhibiting Excellent Long‐Term Operational and UV Stability
Neha Arora,M. Ibrahim Dar,Seckin Akin,Seckin Akin,Ryusuke Uchida,Ryusuke Uchida,Thomas Baumeler,Yuhang Liu,Shaik M. Zakeeruddin,Michael Grätzel +9 more
TL;DR: A simple and low-cost PSC architecture employing dopant-free TiO2 and CuSCN as the electron and hole conductor, respectively, is introduced while a graphitic carbon layer deposited at room temperature serves as the back electrical contact.
Journal ArticleDOI
Minimizing the Trade-Off between Photocurrent and Photovoltage in Triple-Cation Mixed-Halide Perovskite Solar Cells
Thomas Baumeler,Neha Arora,Neha Arora,Alexander Hinderhofer,Seckin Akin,Seckin Akin,Alessandro Greco,Mojtaba Abdi-Jalebi,Ravichandran Shivanna,Ryusuke Uchida,Ryusuke Uchida,Yuhang Liu,Frank Schreiber,Shaik M. Zakeeruddin,Richard H. Friend,Michael Graetzel,M. Ibrahim Dar,M. Ibrahim Dar +17 more
TL;DR: This work stabilized FAPbI3 into a cubic lattice and minimized the formation of photoinactive phases and allowed the fabrication of operationally stable perovskite solar cells yielding reproducible efficiencies approaching 22%.
Journal ArticleDOI
