Journal ArticleDOI
Electron-hole diffusion lengths exceeding 1 micrometer in an organometal trihalide perovskite absorber.
Samuel D. Stranks,Giles E. Eperon,Giulia Grancini,Christopher Menelaou,Marcelo J. P. Alcocer,Tomas Leijtens,Laura M. Herz,Annamaria Petrozza,Henry J. Snaith +8 more
TL;DR: In this article, transient absorption and photoluminescence-quenching measurements were performed to determine the electron-hole diffusion lengths, diffusion constants, and lifetimes in mixed halide and triiodide perovskite absorbers.

Electron-Hole Diffusion Lengths Exceeding 1 Micrometer in an Organometal Trihalide Perovskite Absorber
Samuel D. Stranks,Giles E. Eperon,Giulia Grancini,Christopher Menelaou,Marcelo J. P. Alcocer,Tomas Leijtens,Laura M. Herz,Annamaria Petrozza,Henry J. Snaith +8 more
TL;DR: In this paper, transient absorption and photoluminescence-quenching measurements were performed to determine the electron-hole diffusion lengths, diffusion constants, and lifetimes in mixed halide and triiodide perovskite absorbers.
Journal ArticleDOI
Formamidinium lead trihalide: a broadly tunable perovskite for efficient planar heterojunction solar cells
Giles E. Eperon,Samuel D. Stranks,Christopher Menelaou,Michael B. Johnston,Laura M. Herz,Henry J. Snaith +5 more
TL;DR: In this article, the effect of replacing the methylammonium cation in this perovskite was explored, and it was shown that with the slightly larger formamidinium lead trihalide cation, one can synthesise a peroviscite with a bandgap tunable between 1.48 and 2.23 eV.
Journal ArticleDOI
High Charge Carrier Mobilities and Lifetimes in Organolead Trihalide Perovskites
TL;DR: Organolead trihalide perovskites are shown to exhibit the best of both worlds: charge-carrier mobilities around 10 cm2 V−1 s−1 and low bi-molecular charge-recombination constants.
Journal ArticleDOI
A mixed-cation lead mixed-halide perovskite absorber for tandem solar cells
David P. McMeekin,Golnaz Sadoughi,Waqaas Rehman,Giles E. Eperon,Michael Saliba,Maximilian T. Hörantner,Amir A. Haghighirad,Nobuya Sakai,Lars Korte,Bernd Rech,Michael B. Johnston,Laura M. Herz,Henry J. Snaith +12 more
TL;DR: It is shown that using cesium ions along with formamidinium cations in lead bromide–iodide cells improved thermal and photostability and lead to high efficiency in single and tandem cells.
