Dear Researchers,

It is known that TiO2 and ZnO is the well known material for DSSC due to its some admirable properties. At the same time, these material are also used in Photo-Catalytic activity.

Hence i think TiO2 incorporation on DSSC also the major drawback due to its dye degradation property.

I know, this is the well electron collector or transporter, porosity, well interaction with N719. Even though it has affected the dye.

Suggest the answers for my comments

Thank You
