Two typical carbon materials (ordered mesoporous carbon and carbon nanotube) were chosen as scaffolds in combination with semiconductor quantum dots (SQDs) for making light-harvesting assemblies. The effects of interfacial morphology on photoelectric performance of the carbon-based heterostructures have been investigated in detail. The enhanced photoresponse shows a strong dependence on the interfacial morphology as a result of direct interfacial contacts between SQDs and carbon materials, which plays a major role in increasing charge generation at the interface and transport pathways for photoinduced electron transfer. The methodology to enhance the photoresponse through tuning interfacial morphology proves to be a potent alternative in fabricating photochemical energy conversion systems.
两种典型的碳材料（有序介孔碳和碳纳米管）被选为支架，与半导体量子点（SQD）结合，用于制作光收集组件。详细研究了界面形态对基于碳的异质结构光电性能的影响。增强的光响应强烈依赖于界面形态，这是由于 SQD 和碳材料之间的直接界面接触，这在增加界面处的电荷产生和光诱导电子转移的输运途径方面起着主要作用。通过调整界面形态来增强光响应的方法被证明是制造光化学能量转换系统的一种有效替代方法。
