Solvent-Mediated Crystallization of CH3NH3SnI3 Films for Heterojunction Depleted Perovskite Solar Cells
Feng Hao,Constantinos C. Stoumpos,Peijun Guo,Nanjia Zhou,Tobin J. Marks,Robert P. H. Chang,Mercouri G. Kanatzidis +6 more
TL;DR: Solvent effects on the crystallization of the lead-free methylammonium tin triiodide (CH3NH3SnI3) perovskite films in a solution growth process are investigated to provide important progress toward achieving improved perovkite morphology control in realizing solution-processed highly efficient lead- free perovSKite solar cells.
Journal ArticleDOI
Structural Diversity in White-Light-Emitting Hybrid Lead Bromide Perovskites
Lingling Mao,Peijun Guo,Mikael Kepenekian,Ido Hadar,Claudine Katan,Jacky Even,Richard D. Schaller,Constantinos C. Stoumpos,Mercouri G. Kanatzidis +8 more
TL;DR: A series of new structurally diverse hybrid lead bromide perovskites that have broad-band emission at room temperature and the highest photoluminescence quantum yield is reported, owing to its unique structure that allows efficient charge carrier relaxation and light emission.
Journal ArticleDOI
Ultrafast switching of tunable infrared plasmons in indium tin oxide nanorod arrays with large absolute amplitude
TL;DR: In this paper, the authors demonstrate ultrafast plasmon modulation in the near-infrared (NIR) to mid infrared (MIR) range by intraband pumping of indium tin oxide nanorod arrays (ITO-NRAs).
Journal ArticleDOI
All-Polymer Solar Cell Performance Optimized via Systematic Molecular Weight Tuning of Both Donor and Acceptor Polymers
Nanjia Zhou,Alexander S. Dudnik,Ting I. N. G. Li,Eric F. Manley,Thomas J. Aldrich,Peijun Guo,Hsueh-Chung Liao,Zhihua Chen,Lin X. Chen,Robert P. H. Chang,Antonio Facchetti,Monica Olvera de la Cruz,Tobin J. Marks,Tobin J. Marks +13 more
TL;DR: It is shown that proper and precise tuning of both donor and acceptor polymer Mns is critical for optimizing APSC performance and the importance of optimizing Mn for both polymer components to realize the full potential of AP SC performance is highlighted.
Journal ArticleDOI
