Abstract :
We present and compare different experimental methods used to determine defect introduction rates in materials constituting trijunction solar cells. Most of the experimental methods correlates together and with an analytical modeling. Defect introduction rates values in GaInP and GaAs are presented over a wide range of NIELs; this result seems intrinsic to these two materials.
