我们报道了具有纳米结构等离子体背接触的超薄非晶硅：氢太阳能电池的设计、制造和测量，与具有平坦或随机纹理背接触的电池相比，其短路电流密度有所提高。主要的光电流增强出现在550纳米至800纳米的光谱范围内。我们使用角分辨光电流光谱法来证实增强的吸收是由于与电池所支持的导模耦合。有源非晶硅：氢层中吸收的全场电磁模拟与实验结果吻合良好。此外，纳米图案是通过一种廉价、可扩展且精确的纳米图案化方法制造的。这些结果应该为薄膜太阳能电池优化的、非随机的纳米结构背反射器的设计提供指导。《理解薄膜n - i - p型硅太阳能电池中光散射纹理背电极的光捕获》，《J.》《硅薄膜太阳能电池中的透明导电氧化物和光捕获》，《Sol.》《聚光太阳光下硅太阳能电池的极限效率》，《IEEE Trans.》《薄膜硅太阳能电池和模块的性能现状》，《第23届欧洲会议记录》《用于太阳能电池的纹理光学片的强度增强》，《IEEE Trans.》《用常压化学气相沉积法制备的掺氟氧化锡透明导电氧化物薄膜制成的非晶硅太阳能电池》，《Mater.》《具有纹理衬底的微晶硅太阳能电池中光捕获的潜力》，《Prog.》《纳米粒子增强光电探测器中的岛尺寸效应》，《Appl.

We report on the design, fabrication, and measurement of ultrathin film a-Si:H solar cells with nanostructured plasmonic back contacts, which demonstrate enhanced short circuit current densities compared to cells having flat or randomly textured back contacts. The primary photocurrent enhancement occurs in the spectral range from 550 nm to 800 nm. We use angle-resolved photocurrent spectroscopy to confirm that the enhanced absorption is due to coupling to guided modes supported by the cell. Full-field electromagnetic simulation of the absorption in the active a-Si:H layer agrees well with the experimental results. Furthermore, the nanopatterns were fabricated via an inexpensive, scalable, and precise nanopatterning method. These results should guide design of optimized, non-random nanostructured back reflectors for thin film solar cells.
