title: Performance improvement of dye-sensitized glass powder added TiO2 solar cells.
abstract: The effect of two different types of glass powder added TiO2 hydride photoelectrode in performance of dye sensitize solar cell (DSSC) had been studied at different wt.%. TiO2 particles diffusion and possible attachment with Si atoms was observed with field-emission scanning electron microscopy (FE-SEM) and it strongly depends on characteristics of glass. Short circuit current (I(sc)) was increased with increasing the wt.% up to 5% of glass powder and further increase in wt.% ratio had decreased the I(sc). Maximum increase upto 32 and 45% in the efficiently was observed at 5 wt.% of glass powder in TiO2 for low temperature (LTG) and high temperature glass (HTG) powder, respectively. Adding glass powder in TiO2 can increase light scattering properties of hybrid electrode and can also create an energy barriers of SiO2 which prevents the recombination reactions, hence; an increase in efficiency observed.
