The precursor sol can be either deposited on a substrate to form a film (e.g., by dip-coating or spin coating), cast into a suitable container with the desired shape (e.g., to obtain monolithic ceramics, glasses, fibers, membranes, aerogels), or used to synthesize powders (e.g., microspheres, nanospheres).

If the B-X-B angle deviates too far from 180°, phase transitions towards non-luminescent or all-together non-perovskite phases can occur. [121] [122] If the B-X-B angle does not deviate very far from 180°, the overall structure of the perovskite remains as a 3D network of interconnected octahedra, but the optical properties may change.
Crystal structure of CH 3 NH 3 PbX 3 perovskites (X=I, Br and/or Cl). The methylammonium cation (CH 3 NH 3 +) is surrounded by PbX 6 octahedra. [13]The name "perovskite solar cell" is derived from the ABX 3 crystal structure of the absorber materials, referred to as perovskite structure, where A and B are cations and X is an anion.
P2i Ltd was established as a stand-alone company in 2004, as the first DSTL technology spin-out managed by Ploughshare Innovations (the DSTL's technology transfer company). [ 19 ] On 13 July 2010, P2i announced the acquisition of Surface Innovations Ltd, a UK-based technology company with several functional nano-coating patent families in areas ...
Laurell Technologies WS-400 spin coater used to apply photoresist to the surface of a silicon wafer. Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.
LSM is primarily an electronic conductor, with transference number close to 1. This material is commonly used as a cathode material in commercially produced solid oxide fuel cells (SOFCs) because it has a high electrical conductivity at higher temperatures, and its thermal expansion coefficient is well matched with yttria-stabilized zirconia ...
Although the perovskite structure is named after CaTiO 3, this mineral has a non-cubic structure. SrTiO 3 and CaRbF 3 are examples of cubic perovskites. Barium titanate is an example of a perovskite which can take on the rhombohedral (space group R3m, no. 160), orthorhombic, tetragonal and cubic forms depending on temperature. [7]
Slot-die coating is a non-contact coating method, in which the slot-die is typically held over the substrate at a height several times higher than the target wet film thickness. [23] The coating fluid transfers from the slot-die to the substrate via a fluid bridge that spans the air gap between the slot-die lips and substrate surface.
