Comparative Study on the Photovoltaic Properties of Dye-Sensitized Solar Cells (DSCs) Based on Different Counter Electrode Configurations

T. O. Ahmed, N. Alu & A. Y. Abdul Rahman · Journal of Materials Science Research and Reviews · 2019

Previously, we reported an investigation on Delonix regia dye extract as a natural sensitizer for TiO2/DSC assembled with platinum counter electrode and low power conversion efficiency was recorded. This necessitated the current investigation on Delonix regia dye extract as a nat...

Fabrication of TiO2/Dye-Sensitized Solar Cells (DSCs) Using Dye Extracts and Their Mixture as Photosensitizers

T. O. Ahmed, P. O. Akusu, N. Alu & A. L. Aluko · Current Journal of Applied Science and Technology · 2019

In this work we have reported an investigation on Hibiscus sabdariffa and Delonix regia dye extracts and their mixture as natural sensitizers for TiO2/DSCs. A shift in the absorption maximum toward the lower energy of the ultraviolet-visible spectrum was observed for the dye mixt...

Dye-Sensitized Solar Cell (DSC) Based on Titania Nanoparticles and Hibiscus sabdariffa

T. O. Ahmed, P. O. Akusu, N. Alu & M. B. Abdullahi · Current Journal of Applied Science and Technology · 2013

Natural dye extracts from Hibiscus sabdariffa (popularly called Zobo in Nigeria; Western part of Africa) has been used as a sensitizer for nanosized titania (TiO2) synthesized via hydrothermal route. The SEM-EDS analysis revealed the wide band gap titania (TiO2) to be almost isom...
