The components Zn and Al are much cheaper and less toxic compared to the generally used indium tin oxide (ITO). One application which has begun to be commercially available is the use of ZnO as the front contact for solar cells or of liquid crystal displays. Transparent thin-film transistors (TTFT) can be produced with ZnO.

Zinc. Zinc is a lustrous bluish-white metal. It is found in group IIb of the periodic table.It is brittle and crystalline at ordinary temperatures, but it becomes ductile and malleable when heated between 110°C and 150°C. From Wikipedia, the free encyclopedia Zinc acetate is a salt with the formula Zn (CH 3 CO 2) 2, which commonly occurs as the dihydrate Zn (CH 3 CO 2) 2 ·2H 2 O. Both the hydrate and the anhydrous forms are colorless solids that are commonly used in chemical synthesis and as dietary supplements. Again, the effectiveness of Zn can be enhanced by using chloroquine as an ionophore while Zn inside the infected cell can stop SARS-CoV-2 replication. Given those benefits, this perspective paper describes how and why Zn could be given due consideration as a complement to the prescribed treatment of COVID-19. Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite.
