| 英文摘要 | we present performance improved ternary bulk heterojunction polymer solar cells by doping a small molecule, 2,4-bis[4-(n,n-diisobutylamino)-2,6-dihydroxyphenyl] squaraine (dib-sq), into the common binary blend of poly(3-hexylthiophene) (p3ht) and [6,6]-phenyl-c-71-butyric acid methyl ester (pc71bm). the optimized power conversion efficiency (pce) of p3ht:pc71bm-based cells was improved from 3.05% to 3.72% by doping 1.2 wt % dib-sq as the second electron donor, which corresponds to, similar to 22% pce enhancement. the main contributions of doping dib-sq material on the improved performance of pscs can be summarized as (i) harvesting more photons in the low-energy range, (ii) increased exciton dissociation, energy transfer, and charge carrier transport in the ternary blend films. the energy transfer process from p3ht to dib-sq is demonstrated by time-resolved transient photoluminescence spectra through monitoring the lifetime of 700 nm emission from neat p3ht, dib-sq and blended p3ht:dib-sq solutions. the lifetime of 700 nm emission is increased from 0.9 ns for neat p3ht solution, to 4.9 ns for neat dib-sq solution, to 6.2 ns for p3ht:dib-sq blend solution. |
