A hybrid electrolyte involving tetramethylammonium (TMA) hydroquinone/benzoquinone redox couple is formulated. This electrolyte is more transparent than the traditional I − /I 3 − electrolyte and has negligible absorption in the visible region. Dye‐sensitized solar cells using the hybrid electrolyte show higher light‐to‐electricity conversion efficiency. FTO=fluorine‐doped tin oxide.
