| Summary: | Flexible Dye Sensitized Solar Cell (FDSSC) have attracted great attention due
to its ability to install at curved and uneven surface. Therefore, several flexible
substrates including plastic and metal substrate have been chosen to replace
rigid glass substrate for DSSC application. However, due to the weak thermal
stability of plastic Indium Tin Oxide Polyethylene Terephthalate (ITO-PET)
substrate that limit the sintering process at 150℃, metal titanium (Ti) substrate
was chosen as photoanode substrate due to its high thermal stability as well as
good electrical conductivity. The main challenge for metal substrate is the
opaqueness of metal substrate that need to be operated under back illumination
method which will reduce the light penetration thus lead to the low power
conversion efficiency. Consequently, the Platinum (Pt) layer on the ITO-PET for
the counter electrode (CE) side need to be properly choose to allow sufficient
light penetration under back illumination method. In this study, several
experiments have been conducted to improve the efficiency of DSSC until the
fabrication of flexible DSSC (FDSSC). During the fabrication of FDSSC, the
titanium dioxide (TiO2) was deposited onto Ti foil using Doctor-Blade method
while platinum (Pt) was deposited using sputtering method onto ITO-PET. The
highest efficiency of FDSSC with 2.03% has been achieved by applying and pretreatment
of hydrogen peroxide (H2O2) Ti foil as photoanode substrate and 7 nm
thickness of Platinum (Pt) layer on ITO-PET as CE substrate under back
illumination method. |
