TL;DR: In this article, a systematic and comprehensive understanding of the origin, classification, nature, relationships and overlapping effects of defects in perovskite solar cells is summarized and reviewed, while point defects, undercoordinated ions, impurities and pinholes are categorized based on a dimension-criterion.

TL;DR: A seeded growth technique for building a library of single-crystal copper foils with sizes of about 30 × 20 square centimetres and more than 30 kinds of facet, and it is shown that this technique is also applicable to the growth of high-index single-Crystal nickel foils, and the possibility of using the authors' high- index copper foiling as substrates for the epitaxial growth of two-dimensional materials is explored.

TL;DR: In this paper, the modification effect of a Si-P master alloy on Al-24%Si alloy was investigated by using electron probe micro-analyzer (EPMA) and optical microscopy (OM).

TL;DR: In this paper, the authors performed molecular dynamics simulations to study the interaction between the graphene nanoribbon and single-wall carbon nanotube (SWCNT) and found that the GNR enters the SWCNT spontaneously to display a helical configuration which is quite similar to the chloroplast in the spirogyra cell.

TL;DR: In this article, a novel kind of highly efficient photocatalyst composed of ultrathin P-doped ZnO nanosheets decorated with atomic MoS2 layers is reported.
