A proof of concept study for determining quantitative shunt values from contactless photoluminescence images is presented. Experimental results calculated from specifically prepared test structures show good agreement with known shunt resistance values. The effect of the front metallisation on the appearance and interpretation of shunts in photoluminescence images is investigated experimentally.
