英文摘要	the performance of polymer solar cells (pscs), based on poly(3-hexylthiophene) (p3ht) and [6,6]phenyl-c-71 -butyric acid methyl ester (pc71bm), were improved by adding poly[(4,8-bis-(2-ethylhexyloxy)-benzo [1,2-b:4,5-b '](dithiophene)-2,6-diyl-alt-(4-(2-ethylhexanoyl)-thieno[3,4-b]thiophene)-2,6-diyl] (pbdttt-c). the absorption region of the ternary blend films is extended into near infrared region (nir). power conversion efficiency (pce) of the ternary blend pscs is improved to 2.48% with 6% pbdttt-c, which is 27% higher than the binary blend pscs. the dominant mechanism for the pce improvement could be attributed to the well balance between photon harvest and charge carrier transport by doping proper concentration pbuttt-c. the energy transfer or charge carrier transfer directly between p3ht and pbdttt-c was investigated, which are found to be positive for the performance improvement of ternary blend pscs.
