Evaluation of Organic Thin Film Solar Cells Using 3-Diode Equivalent Circuit Model with Inverted Diode

Abstract:

We proposed a modified 3-diode equivalent circuit model with an inverted diode for the analysis of the characteristics of bulk hetero junction organic solar cells before and after heat treatment with the reverse bias of -8 V. The dark current density-voltage (J-V) characteristics of the bulk hetero junction organic solar cells before and after heat treatment were measured. From dark J-V characteristics of each organic solar cell, fitting of J-V curve between measured and calculated date was carried out using a modified 3-diode equivalent circuit model with an inverted diode. Using extracted diode parameters, the performances of the bulk hetero junction organic solar cells were compared and evaluated. The measured and calculated J-V characteristics of the bulk hetero junction organic solar cell agreed well, and the organic solar cells were able to be evaluated using the proposed method.
