| Outline of Final Research Achievements |
In this work, we studied the enhancement of organic thin film solar cells by surface plasmon resonance (SPR) phenomena originated from grating-coupled technique and further improved their performance by metal nanoparticles (NPs). The devices of Al/P3HT: PCBM/Metal NPs:PEDOT:PSS/ITO were fabricated. The results from J-V curves indicated that the power conversion efficiency (PCE) of Al-coated grating substrate was 3.10 % which was better than that of flat substrate for 1.55 times. We further developed the Al-coated grating substrate by incorporated gold and silver NPs in to PEDOT:PSS layer. The PCE of Al-coated grating substrate with gold NPs and silver NPs were 3.25% and 3.17%, respectively. This indicated that the light absorption enhancement at the active layer is attributed to SPR excitation with strong near-field distributions penetrated into absorption polymer, which could lead to higher efficiencies due to the increased absorption, thus resulting in higher current generation.
