摘要：
Two newly synthesized naphthodithiophene-based copolymers, PNB, exhibit a low optical bandgap of similar to 1.64 eV with which the solar cells fabricated from the blend of PNB and PC71BM afforded a power conversion efficiency of 5.3% with external quantum efficiency over 60% in a broad spectral range.
