This anomaly is often attributed to various thermal effects but is also observed in flash testing, where thermal effects do not have time to accumulate. As the optically generated carrier density increases past the equilibrium carrier density, open-circuit voltage and other important electrical properties could deteriorate. Using Newton linearizations and the finite-element library deal.II, we developed a computational model to solve the carrier continuity equations for optically generated charge carriers as a function of material depth in bulk III-V semiconductors. © 2015 IEEE. %[ 2021-10-26 %~ Tufts Digital Library %W Institution
