摘要
An electron-transport polymer with good solution processibility, excellent thermal stability, and high electron affinity based on alternating perylene diimide and dithienothiophene units has been synthesized. Electron mobilities as high as 1.3 x 10(-2) cm(2) V-1 s(-1) have been measured in field-effect transistor geometry. The polymer shows broad absorptions throughout the visible and extending into the near-IR. A power conversion efficiency of over 1%, under simulated AM 1.5, 100 mW/cm(2), was measured for a single-layer solar cell using this polymer as an acceptor and a polythiophene derivative as a donor.
