Abstract :
Short-circuit photocurrents (Isc) were investigated for the merocyanine dye LB photoelectric cells in the attenuated total reflection (ATR) configurations. The Isc profiles as a function of incident angle corresponded to the ATR properties in the cells. The optical properties in the cells were calculated. It was estimated that the Isc was caused by the strong optical absorption in the cells related to surface plasmon (SP) excitations. It is expected that photocurrents can be enhanced utilizing the SP excitations in the ATR configuration
