The reduced graphene oxide (rGO) and carbon nanotube (CNT) components and their derivatives grafted with the irregioregular poly(3-dodecyl thio-phene) (rGO-g-PDDT and CNT-g-PDDT) and regioregular poly(3-hexylthiophene) (CNT-g-P3HT and CNT-g-P3HT) polymers were used to improve the morphological, optical, and photovoltaic features of CH₃NH₃PbI₃ perovskite solar cells. The type of carbonic material (CNT or rGO) and regioregularity of grafts affected the cell performances. According to the photoluminescence lifetimes, although the grafted-CNT/rGO components improved the cell characteristics (15.3-20.5 ns), the corresponding bared nanostructures ruined them (3.0-4.9 ns). In similar conditions, via alteration of rGO to CNT, the average cell performance changed to 14.56 from 14.07% for PDDT-grafted systems and to 16.36 from 15.15% for P3HT-based ones. The self-ordering polymers such as regioregular P3HTs simultaneously induced the crystallinity to the polymeric and non-polymeric constituents. The best photovoltaic data including 22.73 mA/cm², 75%, 0.96 V and 16.36% with the narrowest distributions were detected in the CH₃NH₃PbI₃ + CNT-g-P3HT solar cells. Perovskite solar cells were perfectly modified with both rGO-g-P3HT and CNT-g-P3HT agents because of the lowest charge-transfer resistance values (93.2 and 90.1 Ω), the most intensified crystalline peaks, and the largest absorbances.

钙钛矿型太阳能电池中碳纳米管和还原型氧化石墨烯的功能以及相应的改进衍生物的比较

还原的石墨烯氧化物（rGO）和碳纳米管（CNT）组分及其衍生物接枝不规则聚（3-十二烷基噻吩）（rGO-g-PDDT和CNT-g-PDDT）和规则聚（3-己基噻吩） ）（CNT-g-P3HT和CNT-g-P3HT）聚合物用于改善CH ₃ NH ₃ PbI ₃钙钛矿太阳能电池的形态，光学和光伏特性。碳材料（CNT或rGO）的类型和移植物的区域规则性会影响细胞性能。根据光致发光寿命，尽管接枝的CNT / rGO组分改善了细胞特性（15.3-20.5 ns），但相应的裸露纳米结构破坏了它们（3.0-4.9 ns）。在类似条件下，通过将rGO改变为CNT，PDDT接枝系统的平均细胞性能从14.07％降至14.56，而基于P3HT的系统的平均性能则从15.15％降至16.36。自定序聚合物（例如区域规则的P3HT）同时诱导聚合物和非聚合物成分的结晶度。最好光生伏打数据包括22.73毫安/厘米²在CH进行检测，75％，0.96 V和16.36％最窄分布₃ NH ₃碘化铅_3个+ CNT-克-P3HT太阳能电池。用rGO- g -P3HT和CNT- g对钙钛矿太阳能电池进行了完美的改性-P3HT试剂的原因是最低的电荷转移电阻值（93.2和90.1Ω），最强的结晶峰和最大的吸光度。
