TL;DR: Triazatruxene-based compounds are demonstrated as a new class of HTM for the fabrication of highly efficient perovskite solar cells and remarkable power conversion efficiency was achieved using 5,10,15-trihexyl-3,8,13-tris(4-methoxyphenyl)-10, 15-dihydro-5H-diindolo[3,2-a:3',2'-c]carbazole with compos
Journal ArticleDOI
Enhancing Thermal Stability and Lifetime of Solid-State Dye-Sensitized Solar Cells via Molecular Engineering of the Hole-Transporting Material Spiro-OMeTAD
Tadas Malinauskas,Daiva Tomkute-Luksiene,Rüdiger Sens,Maryte Daskeviciene,Robert Send,Henrike Wonneberger,Vygintas Jankauskas,Ingmar Bruder,Vytautas Getautis +8 more
TL;DR: Thermal stability of hybrid solar cells containing spiro-OMeTAD as hole-transporting layer is investigated and suppression of the crystal growth in the holes is demonstrated to be a viable tactic to achieve a significant increase in the solar cell resistance to thermal stress and improve the overall lifetime of the device.
Journal ArticleDOI
Molecular engineering of face-on oriented dopant-free hole transporting material for perovskite solar cells with 19% PCE
Kasparas Rakstys,Sanghyun Paek,Peng Gao,Paul Gratia,Tomasz Marszalek,Giulia Grancini,Kyung Taek Cho,Kristijonas Genevičius,Vygintas Jankauskas,Wojciech Pisula,Mohammad Khaja Nazeeruddin +10 more
TL;DR: In this paper, a dopant-free star-shaped D-π-hole transporting materials coded KR355, KR321, and KR353 were systematically designed, synthesized and characterized.
Journal ArticleDOI
Highly Efficient Perovskite Solar Cells Employing an Easily Attainable Bifluorenylidene‐Based Hole‐Transporting Material
Kasparas Rakstys,Michael Saliba,Peng Gao,Paul Gratia,Egidijus Kamarauskas,Sanghyun Paek,Vygintas Jankauskas,Mohammad Khaja Nazeeruddin,Mohammad Khaja Nazeeruddin +8 more
TL;DR: The 4,4'-dimethoxydiphenylamine-substituted 9,9'-bifluorenylidene (KR216) hole transporting material has been synthesized using a straightforward two-step procedure from commercially available and inexpensive starting reagents, mimicking the synthetically challenging spiro-OMeTAD moiety.
Journal ArticleDOI
