How the Deep Defects and Light Trapping Limit the Cell Voltage and How to Measure Them
Original language description
Recently we suggested a new solar cell loss analysis by using the absorptance or simple external quantum efficiency (EQE) measured with sufficiently high sensitivity to also account for defects. Unlike common radiative-limit methods, where the impact of deep defects is ignored by exponential extrapolation of the Urbach absorption edge, our loss analysis considers the full EQE including states below the Urbach edge and uses corrections for band-filling and light trapping. We validate this new metric on a whole range of photovoltaic materials and verify its accuracy by electrical simulations.
