Abstract
For organic photovoltaics (OPVs) to contribute significantly
to energy generation, they need to be scaled to large areas,
much like all organic electronics. Therefore, there is a need for the
development of a specific model that describes the electrical properties
related to the size effects and cell interconnections.We report
here on the equivalent circuit models for a high-performance series connected
OPV module based on a polymer:fullerene bulkheterojunction
formulation. We examine the validity of the effective single
cell methodology in the conventional framework and suggest
a modified model that includes the net series resistance and additional
parasitic leakage conductions. The photocurrent is found
to follow the diffusion-limited voltage dependence, for which an
empirical treatment enables an improved reproduction of the measurement
near the short-circuit point.
