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.
Journal ArticleDOI
Inorganic caesium lead iodide perovskite solar cells
Giles E. Eperon,Giuseppe M. Paternò,Giuseppe M. Paternò,Rebecca J. Sutton,Andrea Zampetti,Andrea Zampetti,Amir A. Haghighirad,Franco Cacialli,Franco Cacialli,Henry J. Snaith +9 more
TL;DR: In this paper, the authors showed that the organic cation is not essential, but simply a convenience for forming lead triiodide perovskites with good photovoltaic properties.
Journal ArticleDOI
Bandgap-tunable cesium lead halide perovskites with high thermal stability for efficient solar cells
Rebecca J. Sutton,Giles E. Eperon,Laura Miranda,Elizabeth S. Parrott,Brett A. Kamino,Jay B. Patel,Maximilian T. Hörantner,Michael B. Johnston,Amir A. Haghighirad,David T. Moore,Henry J. Snaith +10 more
TL;DR: In this paper, the highest reported efficiency cesium lead halide perovskite solar cells are realized by tuning the bandgap and stabilizing the black perovsite phase at lower temperatures.
Journal ArticleDOI
Lead-Free Halide Double Perovskites via Heterovalent Substitution of Noble Metals
George Volonakis,Marina R. Filip,Amir A. Haghighirad,Nobuya Sakai,Bernard Wenger,Henry J. Snaith,Feliciano Giustino +6 more
TL;DR: In this paper, a new family of Pb-free inorganic halide double perovskites based on bismuth or antimony and noble metals was proposed, which exhibits tunable band gaps in the visible range and low carrier effective masses.
Journal ArticleDOI
Cs2InAgCl6: A New Lead-Free Halide Double Perovskite with Direct Band Gap.
George Volonakis,Amir A. Haghighirad,Rebecca L. Milot,Weng Hong Sio,Marina R. Filip,Bernard Wenger,Michael B. Johnston,Laura M. Herz,Henry J. Snaith,Feliciano Giustino +9 more
TL;DR: This work proposes a new class of halide double perovskites, where the B3+ and B+ cations are In 3+ and Ag+, respectively, and attempts to synthesize Cs2InAgCl6 and Cs1InAgBr6, and succeeds to form the hitherto unknown double perOVskite Cs 2InAgcl6.
