有機太陽能電池中,有機分子的排列堆疊的方式是影響太陽能電池效率的其中一個重要關鍵。本研究利用五聯苯 (pentacene)及其衍生物探討高開路電壓有機太陽能電池。此研究中,分別利用兩個不同的五聯苯衍生物,均在五聯苯的主幹上加上苯環基團,為6,13-dipheynl-pentacene (DP-Penta)及 6,13-Di-bipheynl-4- yl-pentacene (DB-Penta)。利用變角度的X光吸收近邊緣結構(near-edge X-ray absorption fine structure, NEXAFS)量測可得知五聯苯及其衍生物成膜後於基板上具有不同的分子排列,五聯苯為依著長軸站立於PEDOT:PSS表面上,而具有與聯苯主幹垂直之苯環基團的兩個五聯苯衍生物則是平躺於基板表面上。由此材料製做成的小分子有機太陽能電池有很大的差異,利用DB-penta/C60所製作的元件,相對於pentacene/C60的參考標準元件,其開路電壓(Voc)由0.28V提高至0.83V,有明顯的提升。這是因為分子排列平躺著的五聯苯衍生物能夠與上層的C60具有較好的π-π overlap,使得在p-n界面中具有新的電荷分佈,促使真空能階的偏移,更進一步的影響並增加元件的開路電壓。此研究結果可以延伸引用到其他的有機太陽能電池系統,可以有效的增加影響其元件效率。
Molecular stacking orientation is one of the major factors for high performance in organic solar cells. Here, we study the open-circuit-voltage (VOC) of organic heterojunction photovoltaic cells based on pentacene and its derivatives. Two functionalized forms of pentacene- 6,13-dipheynl-pentacene (DP-Penta) and 6,13-Di-bipheynl-4-yl-pentacene (DB-Penta)– have been used for this study. Different molecular stacking orientations of the pentacene-derivatives have been identified by angle dependent near-edge X-ray absorption fine structure (NEXAFS) measurements. It’s concluded that pentacene molecules stand up on the PEDOT:PSS surface, while functionalized pentacene molecules lie down on the surface upon the modification of additional orthogonal phenyl rings. A significant increase of the VOC from 0.28 to 0.83 V has been observed when a conventional pentacene/C60 cell is replaced by the DB-penta/C60 cell. This result can be attributed to the fact that down-lying molecular stacking orientation of the functionalized pentacene induced a vacuum level (V. L.) shift, resulting in improved VOC of the devices. This approach has important implications for organic electronic devices that comprise multiple organic layers, and particularly for improving the power conversion efficiency of organic photovoltaic cells.
