Abstract
In order to effectively improve the efficiency of polymer cell devices, in this study, Ag nanoparticles were simultaneously added in the electron transport layer and hole transport layer to prepare a double plasma polymer solar cell with poly(3-hexylthiophene): [6,6]-phenyl C61 butyric acid methyl ester heterogeneity as the active layer. Furthermore, this study investigates the changes in the performance of a device added with metal nanoparticles. The experimental results revealed that the short-circuit current density and photoelectric conversion efficiency of the device improved after Ag nanoparticles were simultaneously added in the electron transport layer and hole transport layer. The short-circuit current density increased from 2.96 mA/cm2 of a standard device to 7.17 mA/cm2, and efficiency is increased from 0.75 to 2.31%. Furthermore, the plasma resonance effect of the surface of the Ag nanoparticles effectively improved the efficiency of the device.
