The influence of using different concentration of triazoloisoquinoline based small molecule as co-adsorbent to modify the monolayer of a TiO 2 semiconductor on the performance of a dye-sensitized solar cell is studied. The current-voltage characteristics are measured under AM 1.5 (100mW cm-2). The co-adsorbent significantly enhances the open-circuit photovoltage (Voc), the short circuit photocurrent density (J sc) as well as the solar energy conversion efficiency (η). The co-adsorbent 4L is applied successfully to prepare an insulating molecular layer with N719, and achieve high energy conversion efficiency as high as 8.83% at 100mWcm-2 and AM 1.5 at 1 to 0.25 (N719: co-adsorbent) molar ratio. The resulting efficiency is about 6% higher than that of a non-additive device. The result shows that the organic small molecule 4L is the promising candidates for improvement of the performance of dye-sensitized solar cell.
