| Summary: | 碩士 === 國立成功大學 === 微電子工程研究所 === 104 === In this work, the ZnO/Ag/ZnO multilayer film was applied to inverted polymer solar cells (IPSCs) as electron transportation layer to improve power conversion efficiency (PCE) of IPSCs. By inserting a nano-sized Ag layer between bottom ZnO and top ZnO layer, the light transmission of electron transportation layer could be enhanced resulting from local-ized surface plasmon (LSP) of silver nanoparticles at visible wavelength. The power con-version efficiency of IPSCs with ZnO/Ag/ZnO (Ag=8 nm) electron transportation layer improved from 7.25% to 8.13%. Besides, silver nanoparticles was doped into the active layer (PTB7：PCBM) of IPSCs. The light absorption of devices could be enhanced result-ing from optical re-flection by scattering of silver nanoparticles. Compared to the active layer without silver nanoparticles, the power conversion efficiency of IPSCs with PTB7：PCBM：Ag NPs (10：15：0.4) active layer improved from 7.25% to 7.55%. Combinating ZnO/Ag/ZnO electron transportation layer and active layer with silver nanoparticles, the best performance of the IPSCs was obtained that power conversion efficiency was 8.30%.
