Abstract:

A quantum-dot (QD) p-i-n heterojunction solar cell with an increased depletion region is demonstrated by depleting the QD layer from both the
front and back junctions. Due to a combination of improved charged
extraction and increased light absorption, a 120% increase in the
short-circuit current is achieved compared with that of conventional
ZnO/QD devices.
