Polymer solar cells (PSCs) become one of the promising alternatives to their inorganic counterparts because of low cost, high design freedom, environmentally friendly, light and flexible.However, the contradiction between absorption efficiency and short exciton diffusion lengths imposes severe constraints to the efficiency of PSCs.Plasmonic effects can reduce the physical thickness of the active layer as well as keep the optical thickness constant, which can solve the contradictory problem above.There have been tremendous studies on enhancing performance of PSCs, but the improved mechanism has remained to be explored deeply.Raman spectroscopy is a powerful technique that probes the vibrational modes of molecules, providing insight into the interaction of metal and conjugate polymer.Besides, any structural changes in the molecules nearest to the metal surface will be manifested as changes in the positions and/or relative intensities of the peaks in the Raman spectrum.The structural sensitivity allows for examination of the interaction between plasmonic and organic materials.Here, we study the interaction between silver nanowires and optoelectronic materials by Raman spectroscopy.
