Under ultra-high solar concentration, drastic efficiency drops are attributed to a deteriorating fill factor and additional thermal effects. The effects of ultra-high solar concentration on other fundamental electrical properties, such as open-circuit voltage, have yet to be explored in detail. In this work, we discuss our theoretical examination of semiconductor performance under ultra-high ... read moreirradiance. Using advanced numerical analysis techniques and the finite-element library deal.II, we develop a computational model to simultaneously solve the carrier continuity equations and Poisson's equation for optically generated charge carriers and the resulting electric potential as functions of space and time. We use this model to analyze VOC in both dynamic and quasi-steady state conditions. Ultimately, we characterize the relationship between VOC and increasing solar concentration.read less
