Jin Wen,Yicheng Zhao,Zhou Liu,Han Gao,Renxing Lin,Sushu Wan,Chenglong Ji,Ke Xiao,Yuan Gao,Yu-Peng Tian,Jin Xie,Christoph J. Brabec,Hairen Tan +12 more
TL;DR: In this paper , a steric engineering to obtain high quality and photostable widebandgap perovskites (≈1.8 eV) suitable for all-perovskite tandems is reported.
Journal ArticleDOI
Transient Absorption Spectroscopy Studies on Polythiophene–Fullerene Bulk Heterojunction Organic Blend Films Sensitized with a Low‐Bandgap Polymer
Heiko Löslein,Heiko Löslein,Tayebeh Ameri,Gebhard J. Matt,Gebhard J. Matt,Markus Koppe,H.-J. Egelhaaf,Anna Troeger,Vito Sgobba,Dirk M. Guldi,Christoph J. Brabec +10 more
TL;DR: P3HT:PCPDTBT:PCBM ternary blend films are investigated by transient absorption spectroscopy and hole transfer from PCPDT BT-positive polarons to P3HT in the P3 HT:PC PDTBT :PCBM 0.1:1 blend film can be visualized.
Journal ArticleDOI
Ionic dipolar switching hinders charge collection in perovskite solar cells with normal and inverted hysteresis
Osbel Almora,Osbel Almora,Pilar Lopez-Varo,Kyung Taek Cho,Sadig Aghazada,Wei Meng,Yi Hou,C. Echeverría-Arrondo,Iwan Zimmermann,Gebhard J. Matt,J.A. Jiménez-Tejada,Christoph J. Brabec,Mohammad Khaja Nazeeruddin,Germà Garcia-Belmonte +13 more
TL;DR: In this paper, drift-diffusion modeling of the ionic dipole switching from the measurement of fast scanned and long pre-biased electrical response is proposed as a novel protocol for evaluation of limit hysteretic effects in perovskite solar cells.
Journal ArticleDOI
Real-time evaluation of thin film drying kinetics using an advanced, multi-probe optical setup
Nusret S. Güldal,Thaer Kassar,Marvin Berlinghof,Tayebeh Ameri,Andres Osvet,Roberto Pacios,Giovanni Li Destri,Tobias Unruh,Christoph J. Brabec +8 more
TL;DR: In this paper, a novel in situ thin film drying characterization chamber, equipped with white-light reflectometry, laser light scattering and photoluminescence, is presented in combination with grazing-incidence X-ray diffraction on two different polymer:fullerene bulk heterojunctions based on poly-(3-hexylthiophene-2,5-diyl) (P3HT) and polythieno[3,2b]thiopane-diketopyrrolopyrrole-co-thiopnea (DPP-TT
Journal ArticleDOI
