Table 1 Relevant parameters, useful for the evaluation of the solar cell degradation process, extracted from dc analysis (open-circuit voltage Voc, short-circuit current Isc and power conversion efficiency η) and from noise measurements (total trap density NT) at a reference temperature of 300 K.
From: A noise model for the evaluation of defect states in solar cells
