Single wall carbon nanotubes (SWCNTs) have long been proposed as a candidate to enhance existing photovoltaic materials by providing an extension to the light absorbed in the infrared. In this work, we discuss the validity of this statement for silicon solar cells and couple a bifacial silicon solar cell to an organic SWCNT cell in a 4-terminal stack. Single chiral species of (6,5), (7,6), and (10,3) are used in the organic cell and the overall contribution to photocurrent from the SWCNTs is discussed in terms of the diameter dependent quantum efficiency, film thickness, the transmittance of silicon, the spectral overlap of the SWCNT's absorbance with the solar irradiance spectrum and the maximum obtainable current density in the infrared.

长期以来，单壁碳纳米管 (SWCNT) 一直被提议作为增强现有光伏材料的候选材料，它可以扩展红外线吸收的光。在这项工作中，我们讨论了该声明对硅太阳能电池的有效性，并将双面硅太阳能电池与 4 端子堆叠中的有机 SWCNT 电池耦合。有机电池中使用了 (6,5)、(7,6) 和 (10,3) 的单一手性物质，并根据直径相关的量子效率、薄膜厚度讨论了 SWCNT 对光电流的总体贡献，硅的透射率，单壁碳纳米管的吸收与太阳辐照光谱的光谱重叠，以及在红外线中可获得的最大电流密度。
