TL;DR: A bromide-iodide lead perovskite film is demonstrated with an optical bandgap of 1.94 eV, which is optimal for tandem cells of these materials with crystalline silicon devices.
Journal ArticleDOI
Understanding charge transport in lead iodide perovskite thin-film field-effect transistors.
Satyaprasad P. Senanayak,Bingyan Yang,Tudor H. Thomas,Nadja Giesbrecht,Wenchao Huang,Eliot Gann,Bhaskaran Nair,Karl C. Goedel,Suchi Guha,Xavier Moya,Christopher R. McNeill,Pablo Docampo,Pablo Docampo,Aditya Sadhanala,Richard H. Friend,Henning Sirringhaus +15 more
TL;DR: It is shown that through optimization of thin-film microstructure and source-drain contact modifications, it is possible to significantly minimize instability and hysteresis in FET characteristics and demonstrate an electron field-effect mobility (μFET) of 0.5 cm2/Vs at room temperature.
Journal ArticleDOI
Atmospheric influence upon crystallization and electronic disorder and its impact on the photophysical properties of organic-inorganic perovskite solar cells.

TL;DR: It is found that the crystal formation is kinetically driven by the annealing atmosphere, time and temperature, which indicates a critical impact of the atmosphere upon crystallization and the ultimate device performance.
