Performance investigation of n-ZnO nanowire/p-CuO thin film heterojunction solar cell grown by chemical bath deposition and vapour liquid solid technique
Published in Institute of Electrical and Electronics Engineers Inc.
In the present work, the authors report the fabrication of p-CuO/n-ZnO heterojunction grown on (100) n-Si substrate. The CuO thin film has been grown by employing vapour-liquid-solid (VLS) technique and the n-ZnO nanowires are grown by chemical bath deposition (CBD) method. The optoelectronic and the photovoltaic properties of the fabricated devices have been investigated. The heterojunction exhibits a photocurrent of 0.25μA under UV illumination of 13mW/cm 2 at 365 nm. An open circuit voltage of 20mV, short-circuit current density of 7.7mA/cm 2 and a fill factor of 23.3% is obtained from the heterojunction. The overall power conversion efficiency is 0.3%. © 2015 IEEE.
