Abstract

Enlarging the molecular size of zinc phthalocyanine (Pc) dyes three dimensionally with 2,6-diphenylphenoxy substituents significantly reduced the aggregation of the dyes on a TiO(2) surface. As a result, the incident photon-to-current conversion efficiency was improved not only in the Q band but over the whole absorption range, achieving 4.6% energy conversion efficiency under one-sun conditions. Electron lifetime measurements indicated that these Pc dyes do not enhance charge recombination, encouraging further development of Pc.

摘要

用 2,6-二苯基苯氧基取代基将锌酞菁（Pc）染料的分子尺寸在三维方向上扩大，显著降低了染料在 TiO(2)表面上的聚集。结果，不仅在 Q 带，而且在整个吸收范围内，光电流转换效率都得到了提高，在单阳光条件下达到了 4.6%的能量转换效率。电子寿命测量表明，这些 Pc 染料不会增强电荷复合，这鼓励了 Pc 的进一步发展。
