Abstract

Usually, the calculation of the optical generation in solar cell simulations is based on the assumption of constant absorption coefficients. Under certain circumstances, however, the absorption coefficient may depend on the light intensity, for example, if the absorbing material suffers from optical saturation. In this work, we present a simple model taking into account a saturable absorber, which can be easily implemented in standard optical simulation models.
