To improve the performance of organic photovoltaics (OPV) for energy harvesting from blue-light, the OPVs (Ag/BCP/C-60/BPh-BTBT/10 mol% p-doped BPh-BTBT/ITO) are fabricated with several dopants such as F(4)TCNQ, C60F36, HATCN, and Mo(tfd)(3). The power conversion efficiencies of the OPVs with F(4)TCNQ, C60F36, HATCN, and Mo(tfd)(3)-doped BPh-BTBT obtained by white light-emitting diode source are improved with 60, 78, 46, and 49% than those by normal solar light, respectively. Secondary ion mass spectroscopy is performed with the 1-day and 7-days samples after the sample fabrication to observe the dopant distributions in each p-doped layer. Diffusion of dopant is observed only in the F(4)TCNQ-doped BPh-BTBT.
