Abstract Plasmonic enhanced solar cells are widely studied due to their increased performance arising from the metallic nanoparticles light absorption and scattering. In contrast, there are only few reports on solar cells which are based solely on the plasmonic metallic layer as the absorber. These cells are operating by hot electron injection in a Schottky barrier formed between the metallic nanoparticles and a semiconductor. In this work, we present photovoltaic cells which are based on an ultra-thin tunable Au layer as the only light absorbing material. These cells are in the solid state configuration composed of ITO|Au NP's|TiO 2 . High throughput methods are used in order to optimize the performance, which reaches 1 mA cm −2 of current, and a voltage of 100 mV under one sun illumination. The incident photon to electron conversion efficiency is 5.84% at 700 nm, the highest reported for a solid-state device so far. These cells are the first step towards a plasmonic based tandem cell.

固态ITO|Au-NPs|TiO 2 等离子体基太阳能电池

摘要 等离子增强型太阳能电池由于金属纳米粒子对光的吸收和散射而提高了性能,因此得到了广泛的研究。相比之下,仅基于等离子体金属层作为吸收体的太阳能电池的报道很少。这些电池通过在金属纳米颗粒和半导体之间形成的肖特基势垒中注入热电子来运行。在这项工作中,我们提出了基于超薄可调金层作为唯一吸光材料的光伏电池。这些电池处于固态配置,由 ITO|Au NP's|TiO 2 组成。使用高通量方法以优化性能,在一次阳光照射下达到 1 mA cm -2 的电流和 100 mV 的电压。入射光子到电子的转换效率在 700 nm 处为 5.84%,这是迄今为止固态器件报告的最高效率。这些细胞是迈向基于等离子体的串联细胞的第一步。
