The effect of different alkyl chains on the photovoltaic performance of D–π–A porphyrin-sensitized solar cells

Abstract: Compared to the DSSCs based on WH-C1 and YD20 with short alkyl chains, the device sensitized by WH-C2 with the hexyloxy group shows a significantly enhanced Voc, Jsc and power conversion efficiency (η).

“…Despite the substantially lower surface concentration, these molecules however, advantageously increase the PCE of the DSSC by 1.5% compared to that with the same dye but not terminated with alkyl chains (Scheme ) . A similar trend was reported elsewhere (Table ) …”

“…This favorable effect is caused by suppressing reduction of a charge mediating species by electrons from the CB of the MO. The lower PCE of DSSCs with porphyrins bearing long alkyl chain was most likely because the 3‐ up to 5‐carbon atom difference in the terminating alkyl chain of the 20‐ meso substituent did not affect much surface coverage of the TiO 2 with the dye . If an auxiliary donor is introduced in the 20‐ meso position, then a conjugated link is required for efficient electron transfer from the auxiliary donor to the porphyrin macrocycle.…”

“…p -Iodoanisole ( 10 ) was prepared according to the literature procedure. 54 A mixture of 4-iodophenol ( 9 ) (264 mg, 1.2 mmol), methyl iodide (170 mg, 1.2 mmol), and K 2 CO 3 (828 g, 6.0 mmol) in 10 mL of acetone was stirred at 60 °C for 24 h. After cooling to room temperature, the mixture was poured into 100 mL of water and extracted with diethyl ether (3 × 40 mL). The combined organic phase was evaporated under vacuum to remove the solvent.…”
