Table 1. Relevant parameters, useful for the evaluation of the solar cell degradation process, extracted from dc analysis (open-circuit voltage V_oc, short-circuit current I_sc, and power conversion efficiency η) and from noise measurements (total trap density N_T) at a reference temperature of 300 K.
