Proceedings ArticleDOI
Quantitative analysis of crystalline silicon wafer PV modules by electroluminescence imaging
TL;DR: In this article, the authors proposed a method to construct a series of dark currentvoltage curves for each individual solar cell in the PV module by calibrating EL signals of the cells.
Journal ArticleDOI
Transmission electron microscopy based interface analysis of the origin of the variation in surface recombination of silicon for different surface preparation methods and passivation materials
TL;DR: In this article, the root cause of variation in surface recombination for Si wafers after different cleaning processes and for different passivation layers was investigated using a combination of calibrated photoluminescence (PL) imaging and transmission electron microscopy (TEM).
Journal ArticleDOI

TL;DR: InAs/GaAs quantum dots have been subjected to a lateral external electric field in low-temperature microphotoluminescence measurements and it is demonstrated that the dot PL signal could be increased several times depending on the magnitude of the external field and the strength of the internal electric field.
Journal ArticleDOI
The effect of oxygen flow rate and radio frequency plasma power on cubic ZnMgO ultraviolet sensors grown by plasma-enhanced molecular beam epitaxy
TL;DR: In this article, a phase-segregated ZnMgO visible-blind detectors were fabricated with metal-semiconductor-metal interdigitated Ni/Mg/Au contacts and responsivity is compared under different growth conditions.
Journal ArticleDOI
Effect of Diamond Wire Saw Marks on Solar Cell Performance
TL;DR: In this article, the impact of diamond wire marks on the local short-circuit current density across the cell was investigated using photoluminescence imaging and spatially resolved quantum efficiency and reflectance measurements.
