Why does the research on quantum rods as solar cell absorbers lag behind quantum dots, and what novel approaches could be explored to bridge this gap in understanding and application within photovoltaic technologies?
1. Certain sizes of quantum dots (spheres) are more convenient to synthesize than nanorods. It is more difficult to obtain nanorods of the same size along their length.
2. Therefore, the properties of quantum dots (fluorescence spectrum, blinking...) have a narrower shape than that of nanorods. This property is better for the use of these fluorophores.
