In this article, we introduce an electrochemical doping method of amorphous selenium (a‐Se) using NaCl(aq). Recently, an a‐Se photovoltaic device fabricated using this method [I. Saito, W. Miyazaki, M. Onishi, Y. Kudo, T. Masuzawa, T. Yamada, A. Koh, D. Chua, K. Soga, M. Overend, M. Aono, G. A. J. Amaratunga, and K. Okano, Appl. Phys. Lett. 98 , 152102 (2011)] 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.
