Short-circuit photocurrents (Isc) due to surface plasmon excitations have been investigated for the organic solar cells using Langmuir-Blodgett (LB) films of merocyanine (MC) and squarylium (SQ) dyes. Tie MC and SQ dyes exhibit p-type conduction, and the Schottky and Ohmic contacts are obtained at the interfaces between the dye LB films and Al thin films and between the dye LB films and Ag thin films, respectively. Since die Schottky diodes show the photoelectric effects, the Schottky photoelectric cells have been constructed The organic solar cells with two kinds of structures, that is, prism/Al thin film/dye LB film/Ag thin film (type I) and prism/MgF_2, thin film/Al thin film/dye LB film/Ag thin film (type II), have been prepared, In the attenuated total reflection (ATR) method, the types I and II have the Kretschmann and both the Kretsclimann and Otto configurations, respectively. Surface plasmons have been resonantly excited at the interface between Ag thin film and air for the ty … More pe I and at the interfaces between MgF_2, thin film and Al thin film and between Ag thin film and air for die type II. The ATR and I_<sc> properties have been simultaneously measured as a function of the incident angles of the laser beams. The peaks of I_<sc> have corresponded to the resonant angles of the ATR curves. The electric fields and optical absorptions in the cells, have been also calculated using the dielectric constants and the film thicknesses obtained from die ATR measurements. The calculated absorptions in the dye LB layers as a function of the incident angles have corresponded to the results of I_<sc>. It has been estimated that the I_<sc> for both types I and II could be enhanced by the excitations of surface plasmons in the ATR configurations. The enhancement of I_<sc> due to SP excitations and the conversion efficiency of organic solar cells were thought to be related to the aggregation structure of dye molecules. This is a great advantage for developing solar cells, sensing devices, light switches and so on. Less

由于表面等离子体兴奋而引起的短路照片（ISC）已经使用了梅罗糖氨酸（MC）和方形（SQ）染料的Langmuir-Blodgett（LB）膜为有机太阳能电池进行了研究。 TIE MC和SQ染料展示了P型传导，并且在染料LB膜和Al薄膜之间以及染料LB膜和AG薄膜之间的界面上获得了Schottky和欧姆的接触。 Since die Schottky divers show the photoelectric effects, the Schottky photoelectric cells have been constructed The organic solar cells with two kinds of structures, that is, prism/Al thin film/dye LB film/Ag thin film (type I) and prism/MgF_2, thin film/Al thin film/dye LB film/Ag thin film (type II), have been prepared, In the attenuated total reflection (ATR) method, the types I and II分别具有Kretschmann和Kretsclimann和Otto配置。表面等离子体对Ty的Ag薄膜和空气之间的界面引起了共识……更多的PE i以及MGF_2，薄膜和Al薄膜之间的界面以及AG薄膜和空气之间的ag thin film thin Film和Air for Die Type II。 ATR和I_ <sc>属性已被简单地作为激光束入射角的函数进行测量。 I_ <sc>的峰与ATR曲线的谐振角相对应。还使用模具常数和通过模拟ATR测量获得的膜厚度计算了电池中电场和光滥用。染料LB层中计算出的后悔作为入射角的函数与I_ <sc>的结果相对应。据估计，对于I和II类型II的I_ <sc>可以通过ATR配置中的表面等离子体的兴奋来增强I_ <sc>。由于SP兴奋和有机太阳能电池的转化效率，I_ <SC的增强被认为与染料分子的聚集结构有关。这是开发太阳能电池，传感设备，照明开关等的一个很大优势。较少的
