Advanced graphene-based transparent conductive electrodes for photovoltaic applications
New architectures of transparent conductive electrodes (TCEs) incorporating graphene monolayers in different configurations have been explored with the aim to improve the performance of silicon-heterojunction (SHJ) cell ... -
Graphene-based electrodes for silicon heterojunction solar cell technology
Transparent conductive electrodes based on graphene have been previously proposed as an attractive candidate for optoelectronic devices. While graphene alone lacks the antireflectance properties needed in many applications, ... -
High-isolation antenna array using SIW and realized with a graphene layer for sub-terahertz wireless applications
This paper presents the results of a study on developing an effective technique to increase the performance characteristics of antenna arrays for sub-THz integrated circuit applications. This is essential to compensate the ... -
Impact of graphene monolayer on the performance of non-conventional silicon heterojunction solar cells with moox hole-selective contact
In this work, a new design of transparent conductive electrode based on a graphene monolayer is evaluated. This hybrid electrode is incorporated into non-standard, high-efficiency crystalline silicon solar cells, where the ... -
Mapping the conductivity of graphene with electrical resistance tomography
Electronic applications of large-area graphene films require rapid and accurate methods to map their electrical properties. Here we present the first electrical resistance tomography (ERT) measurements on large-area graphene ... -
Optical fibre sensors using graphene-based materials: a review
Graphene and its derivatives have become the most explored materials since Novoselov and Geim (Nobel Prize winners for Physics in 2010) achieved its isolation in 2004. The exceptional properties of graphene have attracted ... -
Tunable beam steering enabled by graphene metamaterials
We demonstrate tunable mid-infrared (MIR) beam steering devices based on multilayer graphene-dielectric metamaterials. The effective refractive index of such metamaterials can be manipulated by changing the chemical potential ...
