Near-field photoelectric measurement of Si solar cells
Original language description
This paper treats of nondestructive local silicon solar cell sample measurement and characterization. Used method, harnessing scanning near field optical microscope in reflection regime with keying laser excitation, allows a localization and characterization of structure imperfections. Keyingless and keying optical excitation measurement methods are discussed. Low energy optical excitation permits measurement only in small range of I-V characteristics, where the shunt resistance is dominant. Described method has been adapted for the simultaneous measurement of sample surface topography, its optical properties as well as sample local photoelectric properties. Structure imperfections taking effect on current voltage characteristics were observed and itssize, photoelectric and electric properties were measured. Although the relationships of local imperfection with electric measurement were ascertained, their confirmation will be a subject of ongoing work.
