چکیده
In article number 2203001, Viktor V. Brus and co-workers report on the advanced radiation resistance of high-performance self-powered UV–Vis–NIR (300–800 nm) multi-component hybrid perovskite photodiodes. The devices were exposed to a short impulse 170 keV proton irradiation with fluence up 1013 protons cm−2. Even heavily proton-irradiated photodiodes retain 75% their initial photoelectric characteristics: external quantum efficiency ≥80%, spectral responsivity 0.46 A/W, maximum detectivity 2 × 1012 Jones.

CH(3)NH(3)PbI(3) perovskite / silicon tandem solar cells: characterization based optical simulations.
In this study we analyze and discuss the optical properties of various tandem architectures: mechanically stacked (four-terminal) and monolithically integrated (two-terminal) tandem devices, consisting of a methyl ammonium lead triiodide (CH(3)NH(3)PbI(3)) perovskite top solar cell and a crystalline silicon bottom solar cell. We provide layer thickness optimization guidelines and give estimates...
متن کاملPhase Segregation in Cs-, Rb- and K-Doped Mixed-Cation (MA)x(FA)1–xPbI3 Hybrid Perovskites from Solid-State NMR
Hybrid (organic-inorganic) multication lead halide perovskites hold promise for a new generation of easily processable solar cells. Best performing compositions to date are multiple-cation solid alloys of formamidinium (FA), methylammonium (MA), cesium, and rubidium lead halides which provide power conversion efficiencies up to around 22%. Here, we elucidate the atomic-level nature of Cs and Rb...

متن کاملOptical spectroscopy of two-dimensional layered (C(6)H(5)C(2)H(4)-NH(3))(2)-PbI(4) perovskite.
We report on optical spectroscopy (photoluminescence and photoluminescence excitation) on two-dimensional self-organized layers of (C(6)H(5)C(2)H(4)-NH(3))(2)-PbI(4) perovskite. Temperature and excitation power dependance of the optical spectra gives a new insight into the excitonic and the phononic properties of this hybrid organic/inorganic semiconductor. In particular, exciton-phonon interac...
متن کاملElectronic structures and optical properties of BiOX (X = F, Cl, Br, I) via DFT calculations
Based on the density functional theory (DFT), the lattice constants and atomic positions of BiOX (X = F, Cl, Br, I) species have been optimized, and the electronic and optical properties of the relaxed species have been calculated, with Bi 5d states considered or not. Relaxation generally results in the shrinkage in a and the expansion of c. Relaxed BiOCl, BiOBr, and BiOI present indirect band ...
