Due to the difficulty in measuring these parameters directly, other parameters are substituted: thermodynamic efficiency, quantum efficiency, built-in quantum effectiveness, VOC ratio, and fill factor. Reflectance losses certainly are a percentage of quantum efficiency less than "exterior quantum effectiveness". .
