We investigate the consequences of dimensional confinement on halide double perovskites by synthesizing two-dimensional analogues of the recently reported three-dimensional double perovskite Cs2AgBiBr6. The layered perovskites (BA)4AgBiBr8 (1) and (BA)2CsAgBiBr7 (2) (BA = CH3(CH2)3NH3+) featur...
Although the environmental stability of perovskites has been dramatically improved by constructing 2D perovskites, the PCE of 2D PSCs is still shown inferior performance. Figure1shows the evolution of record PCEs for both Ruddlesden-Popper (RP) and Dion-Jacobson (DJ) 2D PSCs based on the aromati...
Hybrid layered derivatives of double perovskites substantially expand on the substitutional flexibility of halide perovskites to encompass greater compositional and electronic diversity. 机译:我们通过合成最近报道的三维双钙钛矿Cs_(2)AgBiBr_(6)的二维类似物来研究卤化物双钙钛矿的尺寸限制的后果。层状钙钛矿(BA...
Layered halide perovskites and double perovskites optoelectronic properties have recently been the subject of intense research. Layered double perovskites represent the merging of both worlds, and as such, have the potential to further expand the already vast space of optoelectronic properties and applicati...
Further development of the two series up to seven layers illustrates the structure-property relationships in these systems, aiding future materials design and selection in solar cell device engineering and beyond. Summary Two-dimensional hybrid halide perovskites offer high chemical versatility, strong ...
Two-dimensional halide perovskites (2D PVSKs) have drawn tremendous attentions owing to their outstanding ambient stability. However, the random orientation of layered crystals severely impedes the out-of-plane carrier transport and limits the solar cell performance. An in-depth understanding coupled wit...

such as lead-halide perovskites, CdZnxTe1-x(e.g. CdTe), and double perovskites (Fig.4a). We took radiographs of BiOI single crystals in a side-by-side comparison with silicon, and showed that far fewer X-rays were transmitted (only 2%, compared to 78% for silicon), demonstrating the ...
