Abstract
An easy-to-use technique for the localization and imaging of local shunts in solar cells is introduced. The method is based on temperature-sensitive polymer-dispersed cholesteric liquid crystal foils, covering the reverse-biased solar cell. The unique optical properties of the cholesteric liquid crystal, known as selective reflection, render the local shunts of a solar cell visible as a color distribution in the foil, which is directly correlated with the spatial shunt distribution. The novel method is applied to several laboratory and commercial silicon solar cells and its high sensitivity is demonstrated.
