| 内容記述 | Organic polymer solar cells (OPSCs) are promising candidates for renewable energy sources due to their advantages of low-cost solution process capability, flexibility, and scalable production. However, the power conversion efficiencies (PCEs) of OPSCs require the improvement of solar light utilization through light management. This strategy allows great enhancement of the light harvesting in OPSCs. Moreover, improving the light absorption in such OPSCs at a limited thickness of organic photoactive layer is challenging. There are two parts of the present research. Chapter II demonstrates the investigation of the effect of micro/nanoarchitectures or nanopatterns on the performances of OPSCs based on ITO/PEDOT:PSS/P3HT:PCBM/Al device configuration, and chapter III reports the investigation of dual plasmonic system introduced into the OPSCs in order to improve their light harvesting properties. In Chapter II, the effect of imprinted nano/microstructures on the active layer (organic thin film) on performances of bulk-heterojunction (BHJ) OPSCs has been investigated and demonstrated. Patterned structures of the photoactive layer from compact disk recordable (CD-R), Blu-ray disk recordable (BD-R), nanodot, nanowell and honey comb were employed in this study. It was found that the nanostructures improved the light trapping in the OPSCs, which came up with higher PCE as compared to that of a bare device. The texture patterns acted as the diffraction structure for operating the induced strong diffusion and diffraction of incident light. The devices consisted of nano/microstructure-imprinted P3HT:PCBM and Al thin films. In comparison of the optical characteristics and the performances of pristine and imprinted BHJ OPSCs with a variety of the nano/microstructures, it was found that the nano/microstructures increased the short circuit current (I_<sc>), the fill factor (FF), %PCE and the cell performances. Moreover, the different types of the nano/microstructure affected the light tapping, which led to higher efficiencies due to the increased absorption, thus resulting in better current generation. The best %PCE of 3.09 with highest improvement (24.09%) was observed for our OPSC imprinted with a BD-R grating (pitch size of 320 nm). In Chapter III, we also studied the performance enhancement of OPSCs by introducing surface plasmon resonance (SPR) phenomena originated from grating-coupling technique and addition of plasmonic metallic nanoparticles (NPs) such as Au NPs, Ag NPs, Ag nanospheres (NSs) and a series of Ag nanodisks (NDs) into PEDOT:PSS hole transport layer (HTL). The device configuration designed was of grating-imprinted Al/P3HT:PCBM/metal NPs:PEDOT:PSS/ITO. The best device performances in terms of high current density, high charge mobility, and high PCE were found with dual plasmonic system based on both Al grating on device and Ag NDs incorporated into HTL. It was found that dual plasmonic device with Ag NDs (size of ca. 70 nm) revealed the best performances with %PCE of 3.59 and % improvement of 20.47. The results above indicated that the light absorption enhancement at the active layer was caused by SPR excitation with strong near-field distributions penetrated into absorption polymer and the broadband absorption enhancement in the rage of 350-800 nm leads to higher efficiencies, thus resulting in better current generation. | |||||
