在这里，我们报告了在聚（3-辛基噻吩）/富勒烯异质结太阳能电池中加入多壁碳纳米管（MWNT）。多壁碳纳米管（MWNT）通过氧等离子体处理进行功能化。氧等离子体处理的 MWNT 的光电子能谱研究显示羟基和羧基的表面修饰。将等离子体处理的 MWNT 与聚 (3-辛基噻吩) 结合，制成结构为 Au/P3OT + MWNT/C60/FTO 的太阳能电池。制造的器件显示短路电流密度 (Jsc) 开路电压 (Voc)、填充因子和转换效率分别为 0.04 mA/cm2、0.355 V、21% 和 0.003%。与没有 MWNT 的器件相比，掺入 MWNT 制造的太阳能电池显示出更好的器件性能。聚合物复合材料中的多壁碳纳米管充当激子解离位点并提供有效的空穴传输，从而提高器件性能。
Here, we report incorporation of multiwalled carbon nanotubes (MWNTs) in Poly(3-octylthiophene)/fullerene heterojunction solar cells. Multi-walled carbon nanotubes (MWNTs) were functionalized by oxygen plasma treatment. Photoelectron spectroscopy study of oxygen plasma treated MWNTs shows surface modification with hydroxyl and carboxyl groups. Plasma treated MWNTs were combined with Poly(3-octylthiophene) and solar cell was fabricated with the structure Au/P3OT + MWNTs/C60/FTO. Fabricated device shows short circuit current density (Jsc) open circuit voltage (Voc), fill factor and conversion efficacy as 0.04 mA/cm2, 0.355 V, 21% and 0.003%. Solar cell fabricated with incorporation of MWNTs shows much better device performance, then that of the device without MWNTs. MWNTs in the polymer composite act as exciton dissociation site and provide efficient hole transportation, and thereby improving device performance.
