Customer ServiceThere are many proposed quantum dot solar cells configurations. The functional principle of QD-sensitized solar cell is the same as that of DSSC. The difference is that the dye in DSSC is replaced with quantum dots. This class of third generation solar cell is promising and recently attracting considerable attention.
The operation principle of quantum dots sensitized solar cell is similar to that of the dye sensitized solar cells DSSCs. In a quantum dot,confinement effect arises from size effect when particle size is smaller or comparable to exciton Bohr radius. As the size of the quantum dot decreases its characteristic excitonic beak get blue shifted.
The adjustable bandgap of quantum dots allow the construction of nanostructured solar cell that is able toharvest more of the solar spectrum.QDs have large intrinsic dipole moments, which may lead to rapid charge separation.
Researchers have been encouraged to replace the III-V intrinsic region of quantum well solar cell structures with quantum dots due to the efficient management of photo-generated carriers and the advances in multiple quantum well solar cells, as shown in Figure 14.

And because of high electron density in metal (~ 10 22 cm -3), the depletion is negligible on its side of the cell. Depleted heterojunction cell
