Abstract

This paper presents the results of an experimental study regarding the illumination effect on the series resistance of organic solar cells. This effect must be understood and taken in consideration when using organic solar cell in systems and when analyzing performance degradation. Our simulation is done on a device based on a composite of poly (2-methoxy-5-(2’-ethylhexyloxy)-1, 4-phenylenevinylene (MEH-PPV), and [6, 6]-phenyl C60 butyric acid methyl ester (PCBM) under various AM1.5 solar simulator light intensities.

Keywords: Series resistance; Organic solar cell; Current-voltage characteristics.
