The TCO (transparent conducting oxide) substrate is a critical component for dye-sensitized and perovskite solar cells. It should have high transmission, good conductivity, and promote good adhesion for the deposited layers. Dyenamo offers FTO (fluorine-doped tinoxide) glass especially designed for such applications. The different products have been developed to meet the criteria of substrates for DSSC working and/or counter electrodes. The glass can be as thin as 1.1 mm, resulting in reduced device thickness and weight.
