چکیده انگلیسی
Development of innovative low-cost and efficient DSSCs (dye-sensitized solar cell) device for solar energy conversion is essential. In this present study, the performance of DSSCs based on graphene-titania (TrGO) photoanode using conventional N719 (synthetic dye) and natural green chlorophyll dye (organic dye) were extensively studied, analysed and discussed. TrGO was successfully synthesized via one step sol precipitation peptization technique using titanium (IV) isopropoxide (TTIP) and reduced graphene oxide (rGO) as starting materials. It was found that TrGO-2 exhibited the highest photocurrent generation among samples regardless of dye type. DSSCs device fabricated using N719 dye showed 9.15Â mAÂ cmâ2 of photocurrent with 3.95% efficiency whereas DSSCs device using natural chlorophyll green dye exhibited photocurrent density of 3.43Â mAÂ cmâ2 with 0.67% efficiency. From the Tauc plot, band gap was narrowed from 3.17Â eV of TiO2 to 2.78Â eV of TrGO considering the graphene extended the absorption range of the film to the visible light region. The main reason was associated with the better surface contact of the TiO2 dopants with the rGO film resulting in a lower charge transfer resistance.
