We report three-dimensional modelling of plasmonic solar cells in which electromagnetic simulation is directly linked to carrier transport calculations. To date, descriptions of plasmonic solar cells have only involved electromagnetic modelling without realistic assumptions about carrier transport, and we found that this leads to considerable discrepancies in behaviour particularly for devices based on materials with low carrier mobility. Enhanced light absorption and improved electronic response arising from plasmonic nanoparticle arrays on the solar cell surface are observed, in good agreement with previous experiments. The complete three-dimensional modelling provides a means to design plasmonic solar cells accurately with a thorough understanding of the plasmonic interaction with a photovoltaic device.
我们报告了等离子体太阳能电池的三维建模，其中电磁模拟与载流子输运计算直接相关。迄今为止，等离子体太阳能电池的描述仅涉及电磁建模，而没有对载流子输运进行实际假设，我们发现这会导致行为上的显著差异，特别是对于基于低载流子迁移率材料的器件。观察到太阳能电池表面的等离子体纳米颗粒阵列增强了光吸收并改善了电子响应，这与先前的实验结果高度吻合。完整的三维建模提供了一种方法，能够在深入理解等离子体与光伏器件相互作用的基础上精确设计等离子体太阳能电池。
