We at das-Nano are very glad to share our last scientific article on graphene research.
Montserrat Fernández and Israel Arnedo have coathored the article entitled “Graphene-Based Electrodes for Silicon Heterojunction Solar Cell Technology” in the Materials journal with Ignacio Torres, Susana Fernández and José Javier Gandía, researchers of the CIEMAT (Center for Energy, Environmental and Technological Research). Materials is an open access journal and you can download the article here.
In this work, the effect of combining indium tin oxide with between one and three graphene monolayers as the top electrode in silicon heterojunction solar cells is analyzed. The following image schematizes the silicon heterojunction solar cell.
das-Nano’s Onyx system has been a key element in this research to measure the electrical conductance of the hybrid electrodes through reflection-mode terahertz time-domain spectroscopy. Examples of conductance maps are shown in the next image.
