Radiation effects on fabricated Cu_2S/CdS heterojunction photovoltaic cells

摘要

The photovolltaic properties including l-V characteristics, junction capacitance (C-V), short- circuit current (I_sc), open-circuit voltage (V_oc), fill factor (ff), efficiency (η), and spectral response of Cu_2S/CdS heterojunction cells have been examined before and after exposure to nuclear radiation. This included γ-rays of Co-60, and electron beams (at 1.5 MeV enegy).
