Investigation of electrical and photovoltaic properties of Au/poly(propylene glycol)-b-polystyrene/n-Si diode at various illumination intensities

Abstract

Electrical and photovoltaic properties of Au/poly(propylene glycol)-b-polystyrene/n-Si diode were investigated under various illumination intensities. Field emission scanning electron microscope micrographs of the interfacial polymer layer were provided for verification of the nano-fibre pattern. The current–voltage (I–V) measurements of the diode in the dark and under various illumination intensities (50–250 mW/cm²) were carried out and the main electrical parameters of the diode such as leakage current (I₀), ideality factor (n), zero-bias barrier height (Φ_B0), series and shunt resistance (R_s and R_sh), density of surface states (N_ss), open circuit voltage (V_oc) and short-circuit current (I_sc) were obtained in these conditions.
