研究了有机光伏电池中酞菁和苝衍生物双分子层的光致发光性能。聚苝衍生物单层在824 nm处表现出光致发光，寿命分别为1.6 ns和0.10 ns。用100 nm酞菁涂层有效地淬灭了100 nm苝衍生物层的稳态和时间分辨光致发光。n型半导体苝衍生物中光生载流子的高迁移率解释了高猝灭效率，这与双分子层的光伏性质对厚度的不敏感是一致的。
The photoluminescent property of a bilayer of phthalocyanine and a perylene derivative, a part of an organic photovoltaic cell, was investigated. The monolayer of the perylene derivative exhibited photoluminescence at 824 nm with lifetimes of 1.6 ns and 0.10 ns. The steady state and time-resolved photoluminescence of the 100-nm perylene derivative layer were efficiently quenched with a 100-nm phthalocyanine coating. The high efficiency of the quenching was explained by the high mobility of the photogenerated carrier in the n-type semiconducting perylene derivative, and agreed with the insensitivity of the photovoltaic property of the bilayer to the thickness.
