In a recent article, Chung et al. [J. Appl. Phys. 115, 034901 (2014)] proposed a novel method to measure series resistances in solar cells quantitatively by dark lock-in thermography. However, the theory to this method contains a mathematical fault; therefore, the method cannot work as expected. Some unphysical predictions and consequences of this theory are reported.
