Celle solari a colorante organico (DSSC): Applicazione in flusso continuo del colorante a substrati di Titania e monitoraggio in situ mediante spettroscopia UV-vis.

Real-time monitoring of dye loading on TiO2 photoanodes for dye sensitized solar cells (DSSCs) has been applied to quantitatively investigate dye uptake kinetics for the benchmark Ruthenium(II)-based dyes, N3 and N719. Two-step kinetic profiles were observed for both dyes, composed by a fast pseudo-first order step followed by a slower, zero-order process. Static impregnation was compared with dye loading under continuous flow conditions using solutions at different dye concentrations. Photovoltaic performances of DSSCs prepared according the two procedures were also evaluated.
