coupling of TiO 2 and PLT15. The Scanning Electron Microscope (SEM) reveals that
the extracted carotene is uniform in structure with lesser amount of pores. The UV–
vis spectroscopy indicates the presence of absorption peaks under low concentration.
Also purification was carried out using diluted dye solution in presence of various
absorption media that reveals Al 2 O 3 -treated absorption is suitable for solar cell application. Hence, using Al 2 O 3 -treated sample underwent for FTIR spectroscopy that
reveals the presence of various functional groups within the dye solution. Finally,
electrical characterization was carried out with the dye in presence and absence of
PLT15-coupled TiO 2 matrix. The result revealed that presence of PLT15 within the
system has improved the photoconversion efficiency of the solar cell due to better
charge collection properties and minimize the surface recombination.
