Effective Phase‐Alignment for 2D Halide Perovskites Incorporating Symmetric Diammonium Ion for Photovoltaics

Advanced Science, 2021
New structural type of 2D AA′n−1MnX3n+1 type halide perovskites stabilized by symmetric diammonium cations has attracted research attention recently due to the short interlayer distance and better charge‐transport for high‐performance solar cells (PSCs).

The origin of Sr segregation at La1-xSrxMnO3 surfaces

, 2011
A uniform distribution of La and Sr in lanthanum-strontium manganites would lead to charged crystal planes, a charged surface, and arbitrarily large surface energy for a bulk crystal.

Device for measuring the contour of a surface [PDF]

, 1978
Light from a source is imaged by a lens onto a surface so that the energy from the source is concentrated into a spot. As the spot across the surface is scanned, the surface moves relative to the point of perfect focus.

Energetics of hydrogen impurities in aluminum and their effect on mechanical properties

, 2001
The effects of hydrogen impurities in the bulk and on the surface of aluminum are theoretically investigated. Within the framework of density functional theory, we have obtained the dependence on H concentration of the stacking fault energy, the cleavage

All-inorganic cesium lead iodide perovskite solar cells with stabilized efficiency beyond 15%

Nature Communications, 2018
Black phase cesium lead iodide perovskite is regarded as a promising candidate for solar cells, but it easily transits to undesired yellow phase. Herein, Wang et al. stabilized the black phase using molecular additives to achieve device efficiency beyond
