The effect of indium doping on photovoltaic properties of chemically synthesized zinc oxide thin-film electrodes

Photovoltaic (PV) performance of chemically synthesized indium-doped zinc oxide (IZO) nanorod electrodes has been investigated by photocurrent density-voltage (J-V). The indium (In) concentration was varied from 2 to 6 at.% for IZO. The J-V measurements as performed under a dark condition and a simu...

Description
Summary:Photovoltaic (PV) performance of chemically synthesized indium-doped zinc oxide (IZO) nanorod electrodes has been investigated by photocurrent density-voltage (J-V). The indium (In) concentration was varied from 2 to 6 at.% for IZO. The J-V measurements as performed under a dark condition and a simulated white light of 80 mW/cm 2 confirmed increase in PV performance with the IZO electrodes, making a peak with the 4 at.% In concentration. The investigated properties of the synthesized In-doped ZnO nanorod electrodes (structural and optical) strongly agreed with the PV results and well support the enhanced PV performance of the IZO electrodes. This clearly indicates that IZO electrodes would be preferred against undoped ones in PV solar cell application. Graphical Abstract
