采用八种不同的衍生物在Al/蒸发染料/Ag二极管结构中系统地研究了含若丹宁环的汞染料族的光伏行为。每个染料膜的行为类似于p型半导体，在Al界面处具有整流势垒，在Ag电极处具有欧姆接触。对于其中一种衍生物，观察到开路光电压高达Voc = 1.5 V，而填充因子在所有情况下均保持f.f.= 0.25。根据薄层色谱法的结果，讨论了染料分子在蒸发过程中和蒸发后的化学稳定性。
Photovoltaic behavior of the merocyanine dye family with a rhodanine ring has been systematically studied by employing eight different derivatives in the diode structure Al/evaporated dye/Ag. Each dye film behaves like a p-type semiconductor with a rectifying barrier at Al interface and an Ohmic contact at Ag electrode. The open circuit photovoltage as high as Voc≃1.5 V was observed for one of the derivatives, while the fill factor remained f.f.≃0.25 in all cases. The chemical stability of the dye molecules during and after evaporation is also discussed on the basis of the results obtained by the thin-layer chromatography.
