摘要：

Organic photovoltaics (OPV) have been shown to have excellent indoor efficiency at light intensities as low as one 10 W/m(2). To fully explore their low light efficiency potential, the density as well as severeness of shunts must be kept as low as possible. In this communication we discuss a novel thermography method allowing to image the shunt distribution in organic solar modules with no electrical contact to the module. This thermography method is based on light excitation (ILIT-illuminated lock in thermography) instead of dark current excitation (DLIT-dark lock-in thermography). Comparison of ILIT with DLIT images reveals the equivalence of these two modes for shunt detection, with ILIT having the advantage of being performed in non-contact mode. (C) 2012 Elsevier B.V.
