摘要

在本篇論文中，我們發展出一種氧化銦錫的奈米結構作為埋入式的電極，並應用在有機高分子太陽能電池上。這種埋入式的奈米電極能夠在體異質接面(Bulk Heterojunctions)中提供三維電荷傳導路徑，可對低載子遷移率的電洞作有效率的收集。因此，在一倍強度(One-Sun)及五倍強度(Five-Sun)的標準光源照射下，其轉換效率分別達到3.4%及4.4%；相對於傳統的薄膜電極的有機太陽能電池，其轉換效率提昇了10%及36%。此外，在五倍強度的光源照射下，元件壽命延長兩倍，達到約110分鐘。

In this paper, distinctive indium-tin-oxide (ITO) nanorods are employed to serve as buried electrodes for polymer-based solar cells. The embedded nano-electrodes allow three-dimensional conducting pathways for low-mobility holes, offering a highly scaffolded cell architecture in addition to bulk heterojunctions. As a result, the power conversion efficiency of a polymer cell with ITO nano-electrodes is increased to about 3.4% and 4.4% under one-sun and five-sun illumination conditions, respectively, representing an enhancement factor of up to 10% and 36% compared to a conventional counterpart. Also, the corresponding device lifetime is prolonged twice as much to about 110 min under five-sun illumination.
