“…Semiconductor quantum dot (QD)-sensitized solar cells (QDSSCs) have attracted much interest because they show some advantages compared to dye-sensitized solar cells [ 1 , 2 , 3 , 4 ]. QDs are beneficial because of their high optical absorption coefficients, multiple exciton generation, and large intrinsic dipole moments [ 4 , 5 , 6 ]. It has been expected that the maximum theoretical efficiency of QD-based solar cells would be 44% [ 7 ], which is much higher than that of traditional single-junction silicon solar cells (about 30%) [ 8 ].…”
