High-precision slot die coating equipment
Slot-die coating is a coating technique in which a solution is delivered onto a substrate via a narrow slot positioned close to the surface. The slot-die has a high aspect ratio outlet controlling the final delivery of the coating liquid onto the substrate. This results in the continuous production of a wide layer of coated material on the substrate, with adjustable width depending on the dimensions of the slot-die outlet. By closely controlling the rate of solution deposition and the relative speed of the substrate, slot-die coating affords thin material coatings with easily controllable thicknesses in the range of 10 nanometers to hundreds of micrometers after evaporation of the precursor solvent.

Flexible perovskite solar modules
Perovskite is a crystalline material with the general molecular formula ABX3, in the shape of an octahedron. It is widely used in photovoltaics, LEDs and other fields because of high photoelectric conversion efficiency. Perovskite solar cells (PSCs) are utilized perovskite structural materials as light-absorbing materials, and are representative of the third generation of high-efficiency thin-film cells.

Flexible perovskite solar cells
A perovskite solar cell (PSC) is a type of solar cell which includes a perovskite-structured compound, most commonly a hybrid organic-inorganic lead or tin halide-based material, as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture. Perovskites have inherent properties such as broad absorption spectrum, fast charge separation, long electron and hole transport distance, and long carrier separation lifetime, making them very promising solid-state solar cell materials.

A perovskite is any material with a crystal structure following the formula ABX3, which was first discovered as the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3). Perovskites have a nearly cubic structure and the chemical formula is ABO3. Typically perovskite compounds have the chemical formula ABX3, where "A" and "B" represent cations and X is an anion bound to both. A large number of different elements can combine to form a perovskite structure. Using this compositional flexibility, scientists can design perovskite crystals with a variety of physical, optical, and electrical properties. Today, perovskite crystals are found in ultrasonic machines, memory chips and current solar cells.
