Abstract

In this study, CdTe solar cells were fabricated, with 12%-13% efficiencies, using CdCl₂ dipping and Freon gas treatments and irradiated with a 6-MeV electron beam of various fluences. The efficiency of the CdCl₂-dipped samples decreased by approximately 61% at a dose of 1 × 10¹⁶ e/cm², while that of the Freon-gas-treated samples was reduced by only 43%. The measured external quantum efficiencies indicated that the short-circuit current density (J_sc) values of the treated devices differed significantly under the electron-beam irradiation. The J_sc of the CdCl₂-dipped samples decreased from 23.5 to 10.8 mA/cm², while that of the Freon-gas-treated samples decreased from 24.7 to 16.4 mA/cm². The drift mobility values, derived through time-of-flight measurements, decreased by approximately 1000 times in the CdCl₂-dipped device and by ~100 times in the Freon-gas-treated device at a dose of 1 × 10¹⁶ e/cm². These results reveal that in electron-beam-irradiated devices, the treatment method influences the reduction in J_sc.
