Study of defect regions local heating in solar cells pn junctions by means of microplasma noise
Original language description
The present paper deals with diagnostics of local defects in crystalline silicon solar cells pn junctions. Local avalanche breakdowns take place in the neighbourhood of these defects at sufficiently high reverse voltage. These breakdowns give rise to microplasma noise which is often characterized by current impulses whose inception time and duration time are random. The effective cross-section of the microplasma region being rather small, the current density may achieve a high value, which in turn can result in local heating of the micro-region and, consequently, the junction destruction. This phenomenon can be observed in solar panels when individual solar cells can go into the reversed-bias state due to the shadowing of a part of the panel. Based onour analysis of the microplasma noise statistical generation-recombination process for a time-dependent generation and recombination coefficients in the course of the impulse separation and impulse duration, an algorithm for determining t
