- The single-junction polymer
solar cells (PSCs) with high power conversion efficiency (PCE) are demonstrated
by firstly incorporating two hyperbranched polymers (CHBPEK
and SHBPES) with carboxylic and sulfonic acid groups to modify the cathode interface. The effect of cathode modification by CHBPEK or SHBPES for conventional PSCs
based on different active-layer materials are systematically investigated.
Compared with traditional LiF/Al, Ca/Al and PFN/Al devices, significant improvement in short circuit current and fill
factors are achieved by employing CHBPEK or SHBPES. In particular, the
device with SHBPES as cathode interlayer can be
achieved with a highest PCE of 9.12%, which are among the high performance
reported for single-junction PSCs modified with hyperbranched interlayers. Importantly,
the influence of the hyperbranched polymer interlayer modification on the
cathode interface is also discussed and found to be
the formation of the stable multi-channel interface dipole based on
quasi-immovable counterions in these polymers. The results supply a feasible
means to obtain the improved JSC and FF for high efficiency PSCs.
