The simulations are performed using COMSOL Multiphysics software. These GaAs solar cells are equally well-suited for indoor use (sensing/surveillance), biomedical implants for tumor monitoring and other applications, and outdoor use. The standard solar spectrum assumed in solar cell analysis is called AM1.5G (AM = air mass), which takes into account the attenuation of the intensity and illumination from all angles (rather than direct from the sun) due to scattering in the atmosphere.
