High photovoltage dye-sensitized solar cells (DSCs) offer an exceptional opportunity to power electrocatalysts for the production of hydrogen from water and the reduction of CO
2
to usable fuels with a relatively cost-effective, low-toxicity solar cell. Competitive recombination pathways such as electron transfer from TiO
2
films to the redox shuttle or oxidized dye must be minimized to achieve the maximum possible photovoltage (V
oc
) from DSC devices. A high V
oc
of 882 mV was achieved with the iodide/triiodide redox shuttle and a ruthenium NCS-ligated dye, HD-2-mono, by utilizing a combined approach of (1) modulating the TiO
2
surface area through film thickness and nanoparticle size selection, (2) addition of a
MgO
insulating layer, and (3) capping available TiO
2
film surface sites post film sensitization with an F-SAM (fluorinated self-assembled monolayer) treatment. The exceptional V
oc
of 882 mV observed is the highest achieved for the popular NCS containing ruthenium sensitizers with >5%
PCE
and compares favorably to the 769 mV value observed under common device preparation conditions.
