Abstract

A dye-sensitized heterojunction of configuration n-TiO2/PD-CuPC-MV/p-CuSCN (where PD = 3,4-pyridinedicarboxylic acid anchored to TiO2, CuPC = copper(II) phthallocyanine tetrasulfonic acid ionically linked to PD, and MV = Methyl Violet complexed to CuPC) is developed to demonstrate the applicability of molecular rectification to dye-sensitized solar cells as a strategy of suppressing recombination. Short-circuit photocurrent, open-circuit voltage, energy conversion efficiency, and incident photon to photocurrent conversion of this system are higher than that of the heterojunctions of configurations n-TiO2/PD-MV/p-CuSCN, n-TiO/CuPC-MV/p-CuSCN, and n-TiO2/MV/p-CuSCN. The impressively high rectification ratio and the mode of anchorage of CuPC toTiO2 are suggested as the cause of superior photovoltaic action of the cell TiO2/PD-CuPC-MV/p-CuSCN.

摘要

开发了一种构型为n-TiO2/PD-CuPC-MV/p-CuSCN的染料敏化异质结（其中PD = 锚定在TiO2上的3,4-吡啶二甲酸，CuPC = 与PD离子连接的铜（II）酞菁四磺酸，MV = 与CuPC络合的甲基紫），以证明分子整流在染料敏化太阳能电池中的适用性，作为抑制复合的一种策略。该系统的短路光电流、开路电压、能量转换效率和入射光子到光电流的转换率均高于构型为n-TiO2/PD-MV/p-CuSCN, n-TiO/CuPC-MV/p-CuSCN和n-TiO2/MV/p-CuSCN的异质结。令人印象深刻的高整流比以及CuPC与TiO2的锚定方式被认为是电池TiO2/PD-CuPC-MV/p-CuSCN具有优异光伏性能的原因。
