We studied the properties of observed defects in n$$^{+}$$/p-InGaP solar cells created by irradiation of protons with different energies.Three majority (hole) and a minority-carrier traps, labeled respectively as HP1 (E$$_{V}$$+0.90$$pm$$0.05eV), HP2 (E$$_{V}$$+0.73$$pm$$0.05eV), H2 (E$$_{V}$$ +0.55eV),and EP1 (E$$_{C}$$ 0.54eV),were identified using deep level transient spectroscopy. All majority-carrier traps were found to act as recombination centers. While the H2 traps present in the proton-irradiated p-InGaP was found to anneal out by minority-carrier injection, the other traps were not.
