提出了一种基于两种不互溶电解质溶液极化界面上光致非均相电子转移的太阳能转换新方法。在水\1，2-二氯乙烷界面敏化的水溶性锌卟啉异二聚体的初步研究显示转换效率约为0.1%，对应的光电流吸收的光子通量比接近1。在水相中氧化还原电对作为超敏化剂的存在下，转化效率增加。还提出了这些界面的特征功率关系，并设想了不直接参与光生和载流子输运的固体电极的太阳能电池的可能性。(C)1999年Elsevier Science S.A. All rights reserved.
A novel approach to solar energy conversion is presented on the basis of photoinduced heterogeneous electron transfer at polarised interfaces between two immiscible electrolyte solutions. Preliminary studies at the water\ 1,2-dichloroethane interface sensitised by water-soluble zinc porphyrin heterodimers exhibited conversion efficiencies around 0.1%, corresponding to a photocurrent to absorbed photon flux ratio close to unity. The conversion efficiency is increased in the presence of redox couples acting as supersensitiser in the aqueous phase. The characteristic power relationship for these interfaces is also presented, surd the possibility of solar cells where no solid electrodes are directly involved in the photogeneration and transport of charge carriers is envisaged.
