Charge dynamics at heterojunctions for PbS/ZnO colloidal quantum dot solar cells probed with time-resolved surface photovoltage spectroscopy

Time-resolved laser-pump X-ray-photoemission-probe spectroscopy of a ZnO (101¯0) substrate with and without PbSquantum dots(QDs) chemically linked to the surface is performed, using laser photonenergies resonant with and below the band gapenergy of the substrate (λ = 372 and 640 nm, hν = 3.33 and 1....
