Photocurrent oscillations in natural dyes-based DSSCs with different mordant and assistants: Their role in oscillations and color stability

Cochineal was used as natural dye together with alum and tin as mordant and five assistants (also called brighteners): citric acid, acetic acid, oxalic acid, sodium metasilicate, and cream of tartar. The mordant improves the adhesion between the dye and the mesoporous, stabilizing and intensifying t...
