Hence, DSSCs do not require ultra high pure materials unlike inorganic solar cells.
DSSC fabricated with the inclusion of nano crystalline materials has been effective in diverting from the classical solid state junction devices.
Materials The chemicals used for the experiment were pure and of analytical grade.

One of the many materials was the plastic as it could reduce the weight and cost, while the performance and lifetime could be reduced [7].
Other materials, e.g., polymers and polyvinyl chloride, were also considered and tested by many scientists, but without distinguished advantages.
