摘要：
This study investigates the influence of gamma-irradiation doses (0-25 kGy) on chromium-doped cadmium oxide (CCO) nanoparticle layers synthesized via reactive DC magnetron sputtering. Results reveal dose-dependent modifications in structural, optical, and electrical properties, with reduced band gap energy where The direct band gap energy decreases from 2.29 eV to 1.88 eV, while the onset band gap drops from 1.84 eV to 1.45 eV, indicating significant changes in the electronic structure, enhanced conductivity, and improved thermal stability. A 25 kGy dose achieves optimal n-CCO/p-Si solar cell performance, yielding a power conversion efficiency (PCE) of 22.02 %. The findings underscore the potential of controlled gamma-dose optimization to enhance CCO layers for advanced photovoltaic applications.
