Abstract
Transfer-printed
silver nanowire transparent conducting electrodes are demonstrated
in lead sulfide–zinc oxide quantum dot solar cells. Advantages
of using this transparent conductor technology are increased junction
surface energy, solution processing, and the potential cost reduction
of low temperature processing. Joule heating, device aging, and film
thickness effects are investigated to understand shunt pathways created
by nanowires protruding perpendicular to the film. A <i>V</i><sub>oc</sub> of 0.39 ± 0.07 V, <i>J</i><sub>sc</sub> of 16.2 ± 0.2 mA/cm<sup>2</sup>, and power conversion efficiencies
of 2.8 ± 0.4% are presented
