Abstract
The depletion region width of metal-oxide/quantum-dot (QD) heterojunction solar cells is increased by a new method in which heavily boron-doped n+-ZnO is employed. It is effectively increased in the QD layer by 30% compared to the counterpart with conventional n-ZnO, and provides 41% and 37% improvement of Jsc (16.7 mA cm-2 to 23.5 mA cm-2) and power conversion efficiency (5.52% to 7.55%), respectively.
