Journal ArticleDOI
Detection of X-ray photons by solution-processed lead halide perovskites
Sergii Yakunin,Mykhailo Sytnyk,Dominik Kriegner,Shreetu Shrestha,Moses Richter,Gebhard J. Matt,Hamed Azimi,Christoph J. Brabec,Julian Stangl,Maksym V. Kovalenko,Wolfgang Heiss +10 more
TL;DR: Here it is demonstrated a possibility to use such inexpensive semiconductors for sensitive detection of X-ray photons by direct photon-to-current conversion and a compelling combination of fast photoresponse and a high absorption cross-section for X-rays, owing to the heavy Pb and I atoms.
Journal ArticleDOI
High-performance direct conversion X-ray detectors based on sintered hybrid lead triiodide perovskite wafers
Shreetu Shrestha,Rene Fischer,Gebhard J. Matt,Patrick Feldner,Thilo Michel,Andres Osvet,Ievgen Levchuk,Benoit Merle,Saeedeh Golkar,Haiwei Chen,Sandro Francesco Tedde,Oliver Schmidt,Rainer Hock,Manfred Rührig,Mathias Göken,Wolfgang Heiss,Gisela Anton,Christoph J. Brabec +17 more
TL;DR: Methyl ammonium lead triiodide perovskite wafers for application in direct conversion X-ray detectors are fabricated by a room-temperature sintering process.
Journal ArticleDOI
Brightly Luminescent and Color-Tunable Formamidinium Lead Halide Perovskite FAPbX3 (X = Cl, Br, I) Colloidal Nanocrystals
Ievgen Levchuk,Andres Osvet,Xiaofeng Tang,Marco Brandl,José Darío Perea,Florian Hoegl,Gebhard J. Matt,Rainer Hock,Miroslaw Batentschuk,Christoph J. Brabec +9 more
TL;DR: A facile and rapid room temperature synthesis of 15-25 nm formamidinium CH(NH2)2PbX3 colloidal nanocrystals by ligand-assisted reprecipitation (LARP) is reported, which has a high photoluminescence quantum yield, colloidal and thermodynamic stability, and is an ideal candidate for optoelectronic devices and applications.
Journal ArticleDOI
Designing ternary blend bulk heterojunction solar cells with reduced carrier recombination and a fill factor of 77
Nicola Gasparini,Xuechen Jiao,Thomas Heumueller,Derya Baran,Gebhard J. Matt,Stefanie Fladischer,Erdmann Spiecker,Harald Ade,Christoph J. Brabec,Tayebeh Ameri +9 more
TL;DR: In this article, a highly ordered polymer is added to a ternary blend of organic solar cells to achieve a high fill factor of 77% in order to overcome the competition between recombination and free charges.
Journal ArticleDOI
Abnormal strong burn-in degradation of highly efficient polymer solar cells caused by spinodal donor-acceptor demixing.
Ning Li,José Darío Perea,Thaer Kassar,Moses Richter,Thomas Heumueller,Gebhard J. Matt,Yi Hou,Nusret S. Güldal,Haiwei Chen,Shi Chen,Stefan Langner,Marvin Berlinghof,Tobias Unruh,Christoph J. Brabec +13 more
TL;DR: An abnormal strong burn-in degradation in highly efficient polymer solar cells is demonstrated caused by spinodal demixing of the donor and acceptor phases, which dramatically reduces charge generation and can be attributed to the inherently low miscibility of both materials.
