Summary: | 碩士 === 中原大學 === 物理研究所 === 103 === Organic solar cells are promising alternative energy owing to low fabrication cost and simple fabrication processes. Although organic solar cells have many advantages comparing with inorganic solar cells, the efficiency of organic solar cells was still inferior to the one of inorganic solar cells. Increasing the device efficiency is essential for real commercialization.
In this work, gold nanoparticles are incorporated in the hole injection layer, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). We found that the device efficiency was enhanced when 10% gold nanoparticles of 22 nm were blended with PEDOT:PSS. We also synthesized gold nanoparticles with various diameters by adjusting the experimental conditions. The device efficiency was enhanced by 29.4 % (power conversion efficiency from 3.61 % to 4.67 %) through blending 10% gold nanoparticles of 30~35 nm. Further increasing of the diameter resulted in poor efficiency.
