Preparation and characterization of the defect–conductivity relationship of Ga-doped ZnO thin films deposited by nonreactive radio-frequency–magnetron sputtering [PDF]

, 2010
Ga-doped ZnO (ZnO:Ga) thin films were prepared by radio-frequency–magnetron sputtering on conventional glass substrates at room temperature. The structural, electrical, and optical properties of these films as a function of argon pressure and film ...

Observation of lower defect density brought by excess PbI2 in CH3NH3PbI3 solar cells

AIP Advances, 2019
The introduction of excess PbI2 into CH3NH3PbI3 precursors has been reported to boost the efficiency of CH3NH3PbI3 solar cell. It was assumed that the excess PbI2 helped to reduce the defect density in CH3NH3PbI3 solar cell.
