摘要: | 因為能源的耗盡,近年來太陽能電池的發展越來越重要,除了以往常用的矽基板太陽能電池,現在也越來越多以有機材料來製作大面積的太陽能電池。在有機太陽能電池的使用上,表面電漿成為一個很有助益的增強效果。表面電漿是一個光與物質的混合現象,在金屬與介電物質的交互作用中,入射光的能量能夠被轉換成電場並且使得太陽能電池有增強效益。
在本實驗中,DDSCAT軟體被用來當成我們的模擬基礎,在此軟體中,我們可以輸入金粒子的大小、折射率和形狀,並且使用不同比例的金粒子埋在介電質中,來模擬出不同的模擬結果。首先,在ITO表面上我們會先鋪上一層金粒子,來後再用有機材料覆蓋在上方,我們所用的有機材料為PEDOT與MEHPPV, PCBM, PC70BM, P3HT和碳六十,分別以三種不同物質來製作太陽能電池,並且用三種不同大小分別為5奈米,10奈米和20奈米的金粒子來做模擬,做出實驗來與DDSCAT軟體的模擬來相對照。 Because the supplies of gas and petroleum are decreasing, the need for the solar energy is increasing. In the past decades, many researches focused on the silicon based solar cell, nowadays, more and more people try to invest more money and researches on organic solar cells due to its high productivity and easily fabricated properties. While in the researches of organic solar cells, surface plasmon resonance can be applied on the use of the organic solar cell because of its special interaction between light and matters, and the light energy can be converted to the solar energy by SPR. In this work, the gold nano-particles are embedded between ITO glass and PEDOT organic materials, which can be the SPR source of this work. By using DDSCAT software provided by Princeton, we can simulate the gold nano-particles with respect to its shape, sizes, and the relative refractive index in organic materials. The organic materials used in this work are PEDOT, MEHPPV, PCBM, PC70BM, and P3HT, which provides us different organic materials. And by using spectrum response instrument, the IPCE efficiency of organic materials with different particle sizes can be calculated. In the last part, the DDSCAT simulation results of the absorption of gold nano-particles can be used to compare with the IPCE efficiency of organic materials. |
