Paper Abstract

NaYF4 nanoparticles are doped into PCDTBT:PCBM blend as a dual function additive to improve light absorption of inverted polymer solar cells. The dependence of device performance on NaYF4 in the blend film is investigated. The results show that the short-circuit current density is apparently enhanced by doping NaYF4 into the active layer while maintaining the open-circuit voltage and fill factor, leading to an increase in power conversion efficiency. NaYF4 maybe play two kinds of role for light absorption enhancement. Up-conversion (UC) emission from Y3+ is observed. The scattering effect of NaYF4 nanoparticles (NPs) enhances the light absorption in visible region. The performance of polymer solar cell doped with NaYF4 is compared with that of undoped. The concept of integrating nanoparticles into active layer suggests a promising and practical pathway for improving absorption of polymer solar cells.
