What are the strategies of achieving low resistivity and high transmission at the same time in fluorine-doped tin oxide tin films prepared by spray pyrolysis or chemical bath deposition techniques?
Fluorine doped Tin Oxide by spray pyrolysis requires optimization of various parameters starting with the processing of the precussor to the deposition conditions. There are different set up for spray pyrolysis that have been reported in literature, some manufactured and others 'home made'. This has lead to variations in optimizing conditions such as substrate distance, flow rate etc. For you to obtain crystalline FTO, the deposition temperature of the substrate should be around 450 degrees during the deposition process. You can try to optimize other conditions basing on your set up.
