dc.description.abstract近年來,許多團隊在有機太陽能電池的效率增進貢獻良多,從單層有機太陽能電池到奈米壓印有機太陽能電池的研究,無論是在有機材料的吸光特性或是電荷收集上都有相當的進展,盼望早日能夠生產出商用的電池。 本研究重點在於吾人以熱壓印製作微米週期結構有機太陽能電池主動層,期望光入射至主動層和鋁電極界面時能在微米光柵結構內多次反射與吸收,增強主動層的吸收率,亦能使主動層和鋁電極間的接觸面積增加,使有效收集到的載子更多。同時以時域有限差分法模擬與光譜儀量測一同驗證此電池結構吸收率的增進,進一步縮小至奈米結構模擬之,並在AM 1.5G的光源下進行效率量測,分析I-V曲線得到電性參數,在施加相同壓力之下,光柵深度10 nm的有機太陽能電池短路電流較平面壓印有機太陽能電池相對提升0.05 mA(6.6 %),光柵深度30 nm的有機太陽能電池短路電流較平面壓印有機太陽能電池相對提升0.118 mA(20 %),意即光柵結構所貢獻的抗反射效果使微米週期光柵有機太陽能電池較平面壓印有機太陽能電池有更高的光電流輸出。zh_TW
dc.description.abstractIn recent years, the efficiency of organic photovoltaic has increasing dramatically through numerous researchers’ contribution. From single layer organic photovoltaic to tandem organic photovoltaic, both the absorbance of photon and charge collection is increasing gradually. We are looking forward to producing commercial batteries. This thesis focuses on enhancement of electron collection efficiency and photon absorbance in organic photovoltaic through thermal imprint lithography on active layer. The enhancement of photon absorbance is proved with spectrophotometer in this photovoltaic, and collaborated with the FDTD simulation. Finally, we perform optical simulation on varying the structure period from micrometer to nanometer scale. The photocurrent of device is measured under standard AM 1.5G solar spectrum for analyzing electrical property by I-V curve. Basing on the same imprint pressure, the short circuit current of depth of 10 nm grating active layer in OPV is 0.05 mA(relative improvement 6.6%) higher than planar one. The same phenomena can be found under higher imprinted pressure that the short circuit current of depth of 30 nm grating active layer in OPV is 0.118 mA (relative improvement 20%)higher than planar one. Therefore, the contribution of anti-reflection caused from imprinted micro-grating structure in OPV can enhance photocurrent more than planar one.en_US
