  • Beschreibung: It has been anticipated that incorporating near-infrared (NIR) electron acceptors into double-cable conjugated polymers will propel the efficiency of single-component organic solar cells (SCOSCs) to a new level, but this kind of polymers has not been reported to date. It is a highly challenging task to develop such polymers due to the synthetic difficulty, and meanwhile realize high performance in SCOSCs owing to the unique charge transport characteristics in NIR acceptors. In this work, we are able to develop double-cable polymers with pendent NIR acceptors via judicious synthetic routes, providing a broad absorption spectrum from 300 nm to 850 nm. More importantly, the charge generation process was significantly improved when replacing two acceptors-substituted monomer by single-substitution in the new double-cable polymers, so that an efficiency over 8% with high photocurrent of 16.6 mA/cm2 could be obtained. In addition, SCOSCs also provided low voltage losses of 0.58 V that was comparable to bulk-heterojunction solar cells. All these results demonstrate the powerful design of NIR acceptors based double-cable polymers and will enable SCOSCs to enter into a new era.
