摘要：
Bulk heterojunction polymer solar cells made from a novel low-bandgap polymer show the highest photocurrent response so far for this class of materials (see figure). Efficiencies up to 3.2% are realized, but this conjugated polymer has the intrinsic capability to reach 7% efficiency because of its material properties. Possible loss mechanisms and improvements are discussed.
