Journal ArticleDOI
A generic interface to reduce the efficiency-stability-cost gap of perovskite solar cells
Yi Hou,Xiaoyan Du,Simon Scheiner,David P. McMeekin,Zhiping Wang,Ning Li,Manuela S. Killian,Haiwei Chen,Moses Richter,Ievgen Levchuk,Nadine Schrenker,Erdmann Spiecker,Tobias Stubhan,Norman A. Luechinger,Andreas Hirsch,Patrik Schmuki,Hans-Peter Steinrück,Rainer H. Fink,Marcus Halik,Henry J. Snaith,Christoph J. Brabec +20 more
TL;DR: Tantalum-doped tungsten oxide forms almost ohmic contacts with inexpensive conjugated polymer multilayers to create a hole-transporting material with a small interface barrier, which eliminates the use of ionic dopants that compromise device stability.
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
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.
Journal ArticleDOI
Photoinduced degradation of methylammonium lead triiodide perovskite semiconductors
Xiaofeng Tang,Marco Brandl,Benjamin May,Ievgen Levchuk,Yi Hou,Moses Richter,Haiwei Chen,Shi Chen,Simon Kahmann,Andres Osvet,Florian Maier,Hans-Peter Steinrück,Rainer Hock,Gebhard J. Matt,Christoph J. Brabec +14 more
TL;DR: In this article, the photoinduced degradation of CH3NH3PbI3 in a vacuum and air (relative humidity 40%) is analyzed by ex situ and advanced in situ technologies.
Journal ArticleDOI
Evaluation of Electron Donor Materials for Solution-Processed Organic Solar Cells via a Novel Figure of Merit
Jie Min,Jie Min,Yuriy N. Luponosov,Chaohua Cui,Bin Kan,Haiwei Chen,Xiangjian Wan,Yongsheng Chen,Sergei A. Ponomarenko,Sergei A. Ponomarenko,Yongfang Li,Christoph J. Brabec +11 more
TL;DR: In this paper, a new merit factor for material applied accessibility containing three parameters, namely synthetic complexity, device efficiency, and photostability, was proposed. And the investigated molecules were ranked according to an industrial figure of merit (i-FOM), while some guidelines for the material design and synthesis were given.
