In order to realize PbS quantum dot superlattice solar cells, the band diagram was investigated. By using PYSA (Photoemission Yield Spectroscopy in Air) measurements, a band diagram different from the previously known evaluation results in vacuum was revealed. Combined with KFM (Kelvin Force Microscopy) and UPS ( Ultraviolet Photoelectron Spectroscopy) measurements, the band state of this new type of solar cell in air has been clarified.
