Ultrathin transparent metal capping layer on metal oxide carrier-selective contacts for Si solar cells
Abstract
<p>Carrier-selective contacts using metal oxide thin films have been proposed and successfully demonstrated for dopant-free Si solar cells. However, the electronic properties of several metal oxide thin films such as MoO <sub>x</sub> can deteriorate easily due to the modification of surface chemical state upon exposure to ambient air. Here, we report the use of an ultrathin Au capping layer on MoO <sub>x</sub> to mitigate the undesired surface chemistry modification. In addition, the Au capping layer also functions as a transparent conducting electrode, thereby potentially allowing the replacement of transparent conductive oxides such as indium tin oxide. We further show that the power conversion efficiency of a simple Au/MoO <sub>x</sub>/n-Si device increases from 0.53 to 6.43% with the incorporation of a grid type electrode at the front surface. Our results provide insights into the design of efficient solar cells incorporating carrier selective contacts without the need to use transparent conductive oxides.</p>
