Journal ArticleDOI
Planar perovskite solar cells with long-term stability using ionic liquid additives
Sai Bai,Sai Bai,Peimei Da,Cheng Li,Cheng Li,Zhiping Wang,Zhongcheng Yuan,Fan Fu,Maciej Kawecki,Maciej Kawecki,Xianjie Liu,Nobuya Sakai,Jacob Tse-Wei Wang,Sven Huettner,Stephan Buecheler,Mats Fahlman,Feng Gao,Feng Gao,Henry J. Snaith +18 more
TL;DR: Addition of an ionic liquid, BMIMBF4, to metal halide perovskite solar cells improves their efficiency and long-term operation under accelerated aging conditions of high temperature and full-spectrum sunlight.
Journal ArticleDOI

Weidong Xu,Weidong Xu,Qi Hu,Sai Bai,Chunxiong Bao,Chunxiong Bao,Yanfeng Miao,Zhongcheng Yuan,Tetiana Borzda,Alex J. Barker,Elizaveta Tyukalova,Zhangjun Hu,Maciej Kawecki,Maciej Kawecki,Heyong Wang,Zhibo Yan,Zhibo Yan,Xianjie Liu,Xiao-Bo Shi,Kajsa Uvdal,Mats Fahlman,Wenjing Zhang,Martial Duchamp,Jun-Ming Liu,Annamaria Petrozza,Jianpu Wang,Li-Min Liu,Wei Huang,Wei Huang,Feng Gao +29 more
TL;DR: A major efficiency limit for solution-processed perovskite optoelectronic devices, for example light-emitting diodes, is trap-mediated non-radiative losses as mentioned in this paper.
Journal ArticleDOI
I2 vapor-induced degradation of formamidinium lead iodide based perovskite solar cells under heat–light soaking conditions
Fan Fu,Fan Fu,Stefano Pisoni,Quentin Jeangros,Jordi Sastre-Pellicer,Maciej Kawecki,Maciej Kawecki,Adriana Paracchino,Thierry Moser,Jerernie Werner,Christian Andres,Léo Duchêne,Peter Fiala,Michael Rawlence,Sylvain Nicolay,Christophe Ballif,Ayodhya N. Tiwari,Stephan Buecheler +17 more
TL;DR: In this paper, the degradation was observed to originate from a few seed points in the perovskite bulk rather than from the interfaces with the charge-selective layers or from the cell edges.
Journal ArticleDOI
Biomaterial surface energy-driven ligand assembly strongly regulates stem cell mechanosensitivity and fate on very soft substrates
Tojo Razafiarison,Claude N. Holenstein,Claude N. Holenstein,Tino Stauber,Tino Stauber,Milan Jovic,Milan Jovic,Edward Vertudes,Edward Vertudes,Marko Loparic,Maciej Kawecki,Laetitia Bernard,Unai Silvan,Unai Silvan,Jess G. Snedeker +14 more
TL;DR: It is revealed that surface energy-driven supramolecular ligand assembly can regulate mesenchymal stem cell (MSC) sensing of substrate mechanical compliance and subsequent cell fate, filling a critical gap in basic understanding of cell–biomaterial interaction.
Journal ArticleDOI
Photovoltaic organic interface for neuronal stimulation in the near-infrared
Marta Jole Ildelfonsa Airaghi Leccardi,Naïg Aurelia Ludmilla Chenais,Laura Ferlauto,Maciej Kawecki,Maciej Kawecki,Elodie Geneviève Zollinger,Diego Ghezzi +6 more
TL;DR: In this article, a photovoltaic organic interface optimized for neuronal stimulation in the near-infrared spectrum is presented. But the interface is limited by the adhesion of conjugated polymers in aqueous environments and the materials responsive in the visible spectrum.
