Paper Abstract

In this work, We report on highly efficient organic solar cells based on bis[2-(4-tertbutylphenyl) benzothiazolato-N, C2,] iridium (acetylacetonate) [(t-bt)2Ir(acac)], a material that has been investigated as dopants in organic light-emitting devices (OLEDs). Organic device with structure of indium tin oxide (ITO)/(t-bt)2Ir(acac):CuPc/C60/BCP/Ag, is fabricated. By doping (t-bt)2Ir(acac) into standard CuPc/C60 OPV cell, a high JSC of 8.23 mA/cm2, VOC of 0.36 V, and an exceptionally high power conversion efficiency of 1.42% are achieved. The performance improvement is mainly attributed to efficient light absorption by (t-bt)2Ir(acac) in the range of 380-500 nm, leading to more effective exciton dissociation. Their findings motivate the use of phosphorescent dyes for increasing photon harvesting as well as charge transfer efficiency.
