TL;DR: An ammonium-cation-passivated Pb-Sn perovskites with long diffusion lengths are developed, enabling subcells having an absorber thickness of ~1.2 μm, and a certified efficiency of 26.4% in all-perovskite tandem solar cells is reported, exceeding that of the best-performing single-junction perovSKite solar cells.

TL;DR: A facile and inexpensive and self-assembled strategy to massively fabricate Ni/Co layered double hydroxides (LDHs) with special three-dimensional hierarchical microsphere structure with well-defined flower-like configuration is developed under mild reaction conditions.

TL;DR: The fabrication of high-performance ultraviolet photodetectors based on a heterojunction device structure in which ZnO quantum dots were used to decorate Zn2SnO4 nanowire suggest that the band alignment engineering on nanowires can be rationally achieved using compound semiconductor quantum dots.

TL;DR: In this paper, a broadband response perovskite photodetectors (PPDs) with low bandgap (≈1.25 eV) (FASnI3)0.6 MAPbI3 )0.4 perovSKite as active layers, exhibiting broadband response from 300 to 1000 nm.

TL;DR: In this article, a novel, high-performance flexible integrated on-chip micro-supercapacitors (MSCs) based on hybrid nanostructures of reduced graphene oxide/Fe2O3 hollow nanospheres using a microelectronic photo-lithography technology combined with plasma etching technique is reported.
