方酸菁染料的光伏效应及HMO计算

本文测试了六个方酸菁染料太阳电池的光伏效应,发现其最大量子效率随染料端基杂环碱性的降低而增大。通过这些染料的溶液吸收曲线与光电流光谱响应曲线的比较,可以认为真空升华固态薄膜中染料分子的聚集状态有利于导电性。此外,应用HMO理论计算的染料分子跃迁能与其最大光电流对应的波数之间有较好的线性关系。

Photovoltaic Effects and HMO Calculation of Squarylium Dyes

The photovoltaic effects of the squarylium dyessolar cells have been measured, it is found that the maximum quantumefficiency of these cells is increased with the decrease of basicities ofthe heterocyclie compounds which the dyes are derivatized from. Thecomparison between the solution absorption spectrum and the photoele-ctric action spectra of short circuit current of the dyes exhibits thatthe aggregate of vacuum-evaporated solid film of the dyes is favourablefor concluctivity. Finally, the transition energies of the dyes which arecalculated by means of HMO theory, have a good linear correlationwith the wave-number corresponding to the maxium photocurrent.
