Original Abstract
The microplasma discharges in the PN junction local defect micro-regions are as a rule, accompanied by the emission of light. This radiation from solar cell PN junctions was measured by means of a optical fibre connected to the optical input of a photomultiplier. By inching the fibre by means of computer-controlled stepping motors above the cell surface a 2-D image of the irradiation local regions has been created. It is seen that a cell of a superficial area of 100 cm2 contains a large number of defects, which depends on applied reverse voltage. This method can be a convenient tool for study and diagnostics of optoelectronic devices.
