Dye Sensitized Solar Cells Based on Diphenylpyranylidene Sensitizers with Mono and Dual Cyanoacrylic Acid Anchoring Groups
To clarify the effect of multi-anchoring groups on diphenylpyranylidene (DP) sensitized solar cells for improving charge-transfer rate, di-anchored DP dyes were synthesized for the first time for comparison with a novel mono-anchored DP dye. A solar cell based on di-anchored dye showed enhanced phot...

| description | To clarify the effect of multi-anchoring groups on diphenylpyranylidene (DP) sensitized solar cells for improving charge-transfer rate, di-anchored DP dyes were synthesized for the first time for comparison with a novel mono-anchored DP dye. A solar cell based on di-anchored dye showed enhanced photocurrent and open circuit voltage compared to mono-anchored dye, leading to 32% higher power conversion efficiency of 5.18%, which resulted from the higher molar extinction coefficient and larger charge transfer resistance in the interface of TiO2 and di-anchored dye. |
