Abstract :

This paper contains a preliminary report on 1-(2-pyridylazo)-2-naphthol (PAN) dye as an organic sensitizer in dye-sensitized solar cell. Initially, we have carried out absorption and cyclic voltammetric studies of (PAN) dye to investigate the absorption of light in the visible region and the conditions for the transition of electrons from photo-excited dye to TiO2 nanocrystal. Experimental results of these two studies indicate that PAN dye can be used as a TiO2 sensitizer. Thus, dye sensitized solar cell with PAN dye, sensitizing the TiO2 nanocrystal has been constructed. SEM and photovoltaic characterizations also were made. From SEM surface characteristics, better attachment of the dye particles with TiO2 nano crystalline particles has been observed. The faicated DSSC provides requisite I-V characteristics but has poor efficiency.
