Heteroatom Engineering of a Dibenzo[g,p]Chrysene-Based Hole Transporting Material Provides High-Performance Perovskite Solar Cells

Keith Gregory Brooks, Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Zhaofu Fei, Bin Ding, Yong Ding

Hole-transporting materials (HTMs) are indispensable for realizing efficient and stable perovskite solar cells (PSCs). Herein, a novel dibenzo[g,p]chrysene-based HTM, termed FTPE-OSMe, is synthesized with peripheral methoxy- and methylthio-groups, which co ...

Surface Passivation of FAPbI3-Rich Perovskite with Cesium Iodide Outperforms Bulk Incorporation

Michael Graetzel, Jacques-Edouard Moser, Shaik Mohammed Zakeeruddin, Mounir Driss Mensi, Jun Ho Yum, Kevin Sivula, Thomas Paul Baumeler, Essa Awadh R Alharbi, Brian Irving Carlsen, Jing Gao, George Cameron Fish, Felix Thomas Eickemeyer, Lukas Pfeifer, Georgios Kakavelakis

Metal halide perovskites (MHPs) have shown an incredible increase in efficiency, reaching as high as 25.7%, which now competes with traditional photovoltaic technologies. Herein, we excluded CsX and RbX (X = I–, Br–, Cl–), the most commonly used cations to ...
