Vertical arrays of ZnO nanowires can decouple light absorption from carrier collection in PbS quantum dot solar cells and increase power
conversion efficiencies by 35%. The resulting ordered bulk heterojunction
devices achieve short-circuit current densities in excess of 20 mA cm(-2)
and efficiencies of up to 4.9%.
