Journal ArticleDOI
Lead-free solid-state organic–inorganic halide perovskite solar cells
TL;DR: In this paper, perovskite solar cells containing tin rather than lead were reported, which have a power conversion efficiency of 5.7% and retain 80% of their performance over a period of 12 hours.
Journal ArticleDOI
2D Homologous Perovskites as Light-Absorbing Materials for Solar Cell Applications
Duyen H. Cao,Constantinos C. Stoumpos,Omar K. Farha,Omar K. Farha,Joseph T. Hupp,Mercouri G. Kanatzidis +5 more
TL;DR: The homologous 2D halide perovskites define a promising class of stable and efficient light-absorbing materials for solid-state photovoltaics and other applications.
Journal ArticleDOI

Importance of Reducing Vapor Atmosphere in the Fabrication of Tin-Based Perovskite Solar Cells
Tze-Bin Song,Takamichi Yokoyama,Takamichi Yokoyama,Constantinos C. Stoumpos,Jenna L. Logsdon,Duyen H. Cao,Michael R. Wasielewski,Shinji Aramaki,Mercouri G. Kanatzidis +8 more
TL;DR: An effective process that involves a reducing vapor atmosphere during the preparation of Sn-based halide perovskite solar cells to solve the problem of poor device reproducibility and limits the overall power conversion efficiencies (PCEs).
Journal ArticleDOI
High Members of the 2D Ruddlesden-Popper Halide Perovskites: Synthesis, Optical Properties, and Solar Cells of (CH3(CH2)3NH3)2(CH3NH3)4Pb5I16
