为了增强聚合物太阳能电池的光吸收,在沉积缓冲层之前,通过在氧化铟锡基板上旋涂金胶体溶液,将不同尺寸的金纳米颗粒(NP)掺入到器件中。研究发现,加入60nm Au NPs后,本体异质结电池的功率转换效率可以从3.50%提高到4.07%,相当于提高了16%。器件性能的提高归因于金纳米粒子的局域表面等离子体激发。我们在此报告的方法是一种简单且快速的解决过程。
To enhance light absorption in polymer solar cells, the Au nanoparticles (NPs) with different sizes were incorporated to the devices by spin-coating Au colloid solution on the indium-tin-oxide substrates prior to deposition of buffer layer. It has been found that the power conversion efficiency of bulk heterojunction cells can be increased from 3.50% to 4.07% after incorporating the 60 nm Au NPs, corresponding to an improvement of 16%. The improved device performance is ascribed to the localized surface plasmon excitation of the Au NPs. The method we report herein is a kind of simple and quick solution process.
