TL;DR: In this article, a method based on the closed space vapor transport deposition was proposed for large-scale production of hybrid perovskite solar cells with high power conversion efficiencies of 16.2%.

TL;DR: In this article, a truly bistable twisted nematic liquid crystal display has been fabricated using photo alignment, which can be switched between the −22.5° and 157° twist states by breaking the anchoring condition on one of the substrates.

TL;DR: In this paper, the in situ formation of superconducting Y-Ba-Cu-O (YBCO) thin films by pulsed-laser deposition is discussed, including the formation of various atomic beams by the pulsed laser, the question of oxygen incorporation during film growth, the transformation from the tetragonal to the orthorhombic phase, the nucleation dynamics and the nature of the interface layers between the YBCO film and the substrates.

TL;DR: In this paper, a bridged-grain structure for low-temperature polycrystalline silicon thin-film transistors (TFTs) is introduced, which can reduce the threshold voltage and sub-threshold swing, increase the on-off ratio, and suppress leakage current and kink effect of TFTs significantly.
