Abstract

While commonly used in Si solar cell characterization, the Suns- Vocmethod of determining series resistance (Rs) is rarely used for CdTe and its alloys. However, it is advantageous relative to the slope method-commonly used in the CdTe community-because it measures series resistance at the maximum power point, at which a solar cell operates. Using the self-consistent predecessor to \mathrm{Suns}-\mathrm{V}_{\mathrm{oc}}, \mathrm{J}_{\mathrm{sc}}-\mathrm{V}_{\mathrm{oc}}, we determine \mathrm{R}_{\mathrm{s}} of two different \mathrm{CdSeTe}/\mathrm{CdTe} solar cell structures to be 0.96 and 2.72 µcm2, with repeated measurements showing little deviation.
