Enhanced efficiency of polymer solar cells by structure-differentiated silver nano-dopants in solution-processed tungsten oxide layer

- Incorporating different structures of Ag NPs in solution-processed WO3 layer.
- The LSPR effect of metallic nanoparticles is represented by FDTD method.
- Enhanced PCE are greatly increased by the LSPR effect of SiAgP and nAgPl.
- Naked Ag nanoparticles decreased the PCE of PSCs due to the interface excitons quenching.
- Avoiding interface excitons quenching is greatly needed for utilizing metallic NPS in PSCs.
