摘要
A method to estimate the junction temperature while operating at high photocurrent levels is presented. The relative responsivity change is measured at high operating current. Using a model for the temperature-dependence of the bandgap, a relation between the relative change in the output power and the internal junction temperature is derived. Good agreement between experimental data and simulations is achieved.
