摘要: 等离子体增感太阳能电池中，层层自组装金纳米粒子的表面等离子体共振能产生光电电流，金纳米粒子层的光电转换效率随表面等离子体共振强度的提升而增加。等离子体增感太阳能电池初步试验光电转换效能为0.75%。利用模型仿真电荷分离的现象、光电电流的产生，以及表面等离子体共振和光电电流产生之间的关系来解释实验结果。在未来，通过优化等离子体增感太阳能电池组件，可以进一步提升其转换效率。这在表面等离子体激活太阳能电池及等离子体太阳能电池领域将有很大应用潜力。Abstract: In plasmon-sensitized solar cells, layer self-assembly of gold nanoparticles surface plasmon resonance can produce photoelectric current. Photoelectric conversion efficiency of gold nanoparticles layer increases with the intensity of surface plasmon resonance. The efficiency is up to 0.75%. We use the model to simulate the phenomenon of charge separation, produce of photoelectric current and relationship between surface plasmon resonance and the photoelectric currents to explain the experimental results. In the future, these nanoparticle materials have considerable potential applications in surface plasmon activated solar cells and solar cells plasmon.
