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.

The photovoltaic conversion efficiency of flexible chalcogenide solar cell devices has recently exceeded 20%, but there is still much room for improvement in open-circuit voltage and fill factor as well as durability, which are determined by carrier non-radiative compounding. Based on this, on December 14, 2020, Xin Li's team at Xiamen University and his collaborating team, Tsutomu Miyasaka's team at Yokohama University, Japan, published in JMCA the research results on the preparation of artemisinin passivated mixed cation chalcogenide thin films for the preparation of durable flexible chalcogenide solar cells with efficiency over 21%. The open-circuit voltage and fill factor of the flexible chalcogenide solar cell were improved by using artemisinin passivated chalcogenide thin film. After optimization, the addition of 0.22 mol% of artemisinin can significantly reduce the film defects and non-radiative compound. Finally, 21.1% photoelectric conversion efficiency was obtained with an open voltage up to 1.126V.
