Abstract

Updated complex refractive index data (n and κ) are compiled for various commercial and research solar module encapsulants. The data are used as inputs to ray-tracing simulations to predict CTM loss for standard screen print solar modules and compared to calculations of CTM loss from actual IV and EQE measurements made at the cell and module levels. It is found that this method results in adequate predictions, with encapsulant low-wavelength cutoff the most important characteristic for minimizing CTM current loss. The n and κ are also used to predict CTM current loss following damp-heat cycling of modules.
