Using computational modeling, we developed a baseline model of the device structure (FTO/TiO2/Cs3Sb2I9/PolyTPD(poly(N,N'-bis-4-butylphenyl-N,N'-bisphenyl)benzidine)/Au), which experimentally achieved a power conversion efficiency (PCE) of 3.7% under white light-emitting diode (WLED) ...

We systematize available experimental data on the crystal structure of the ternary halides K 2 (Rb 2 ,Cs 2 ,Tl 2 )TeBr 6 (I 6 ) and Rb 3 (Cs 3 )Sb 2 (Bi 2 )Br 9 (I 9 ), analyze the general trends in the properties of their single crystals, and examine the key features ...
The promise of a lead‐free and layered inorganic halide perovskite, Cs3Sb2I9, in designing efficient ReRAM and artificial synaptic devices is herein demonstrated. The memristive devices exhibit a reproducible bipolar resistive‐switching with a large on/off ratio of ≈104, an excellent retention ...
Here, changes in the optoelectronic properties and crystal structure of the lead-free perovskite derivative Cs3 Sb2 I9 are reported, caused by pressure-induced lattice compression. At 20.0GPa, Cs3 Sb2 I9 with a wide band gap (2.34eV) successfully broke through the Shockley-Queisser limit (1.34eV...
