This study investigates the potential of neutron transmutation doping (NTD) for enhancing the electrical uniformity of gallium arsenide (GaAs) wafers used in photovoltaic cells. Uniformity is crucial for improving solar cell efficiency, which is a key objective in solar power engineering. We employ the SCALE6.1 code to simulate the impact of NTD on the Radial Resistivity Gradient (RRG) within GaAs wafers for various neutron fluence values. The results demonstrate a clear decrease in RRG with increasing neutron fluence. Notably, acceptable RRG values (below 5%) are achievable for both high (25 Ω.cm) and low (5 Ω.cm) initial resistivity GaAs wafers with moderate neutron fluence levels (7.25x1014 n/cm² and 3.63x1015 n/cm², respectively). This suggests that NTD can effectively improve the electrical properties of GaAs, leading to potentially higher solar cell efficiency.
