Ti-Nanoxide BL/SC

Ti-Nanoxide BL/SC offers a simple and convenient way to create a 50-70 nm compact titania layer by spin-coating the solution (5000 rpm for 30 s, acceleration 2000 rpm/s) and firing the coated substrates at 550°C for one hour.

The resulting compact layers, also referred as “blocking layer”, is a pre-requisite in not only Perovskite Solar Cells but also most solid-state Dye Solar Cells where it acts as an electron-selective barrier on the anode.
