Universal rules for visible-light absorption in hybrid perovskite materials
Masato Kato, Takemasa Fujiseki, Tetsuhiko Miyadera +5
A variety of organic-inorganic hybrid perovskites (APbX3) consisting of mixed center cations [A = CH3NH3+, HC(NH2)2+, Cs+] with different PbX3- cages (X = I, Br, Cl) have been deve…
Quantitative determination of optical and recombination losses in thin-film photovoltaic devices based on external quantum efficiency analysis
Akihiro Nakane, Hitoshi Tampo, Masato Tamakoshi +6
In developing photovoltaic devices with high efficiencies, quantitative determination of the carrier loss is crucial. In conventional solar-cell characterization techniques, howeve…
Optical transitions in hybrid perovskite solar cells: Ellipsometry, density functional theory, and quantum efficiency analyses for CH3NH3PbI3
Masaki Shirayama, Hideyuki Kadowaki, Tetsuhiko Miyadera +10
We report artifact-free CH3NH3PbI3 optical constants extracted from ultra-smooth perovskite layers without air exposure and assign all the optical transitions in the visible/ultrav…
