Nanocomposites Of Multi-Walled Carbon Nanotube/Titanium Dioxide As Photoelectrodes For Enhanced Performance Dsscs

Abstract

- The fabrication of the dye-sensitized solar cell (DSSC) was carried out by
depositing TiO2 pure onto an FTO glass. TiO2 was sold at 450 C ° for 30 min to obtain a
homogeneous crystalline film. Then the film was immersed in the Ruthenium N719
solution for 24 hours at room temperature and in the dark to obtain the photoanode. For a
working electrode, the platinum paste was the deposition of platinum on glass FTO by
thermal evaporation in a vacuum. The (I-/I3
-
) as the electrolyte of the DSSC. The poles
were then combined, and electrolytes were injected between them. We designed the first
device DSSC-1 and the second DSSC-3 where improvements were observed in the DSSCs
parameters device DSSC-3 compared to the device DSSC-1. The performance of the
DSSC of the device DSSC-3 has been improved by adding multi-walled carbon nanotubes
to TiO2 as a photoanode. The J-V curves of the under ambient light power conditions (AM
1.5 G, 100 mW cm-2
) showed that the device DSSC-3 gives the efficiency of the
conversion of the falling photons a current of 8.25 %, which is much better when
compared with the rest of the devices.
