Characterization of a-Se p-n junction fabricated using electrolysis in NaCl aq

In this paper, we introduce an electro-chemical doping method of amorphous selenium (a-Se) using NaClaq. Recently, an a-Se photovoltaic device fabricated using this method [1], has been announced and opened up the potential of a new impurity doping method. This study will further explore its possibilities by doping chlorine (Cl) and sodium (Na) and aim to fabricate a p-n junction by reversing the applied voltage during the electrolysis. The device is characterized through photoelectric measurements. The I-V characteristics show rectification under light illumination.
