On-line monitoring and active control of dye uptake in dye-sensitised solar cells

Real-time monitoring of dye loading (N3 and N719) under continuous flow conditions on TiO 2 photoanodes for dye-sensitized solar cells has been applied to quantitatively investigate dye uptake kinetics, demonstrating that static impregnation provides in all cases higher dye loading and, as a consequence, better working devices. © 2011 The Royal Society of Chemistry.
