GreEnergy Consortium Meeting CM3

The GreEnergy 3rd Consortium Meeting took place on 24-25 November 2021 as a hybrid meeting, online and at AMO (Aachen, Germany). It was a pleasure to meet each other after almost 1 year of full online meetings!

In addition to the fruitful scientific discussion about the project progress and challenges, we enjoyed visiting the cleanroom at AMO and discovering the historic center of Aachen, with his famous Christmas market!

Researchers from Chalmers have demonstrated fabrication of high-power density energy storage devices using alkyl-amino functionalized reduced graphene oxide (rGO).

By utilising conventional cleanroom technologies such as spin-coating, lithography and reactive ion etching, they have demonstrated fabrication of complementary-metal-oxide semiconductor (CMOS) compatible on-chip energy storage devices called micro-supercapacitors (MSCs). These devices when combined with energy harvesting units such as solar energy, thermoelectric, or vibrational energy harvesters can potentially replace batteries in on-chip electronics.

Spin-coated MSCs often suffer from poor electrode thickness that leads to low energy densities. Vyas and co-workers address this issue by demonstrating MSCs fabricated of alkyl-amino functionalized reduced-graphene-oxide–heptadecan-9-amine (rGO-MSCs) for enhanced electrode thickness, high capacitance, and lower series resistance compared with functionalized graphene oxide-based MSCs (GO-MSCs).

The functionalized rGO solves a significant issue of inadequate electrode thickness in wafer-scale MSC fabrication while achieving higher energy densities in fewer spin coatings.

In GreEnergy, these newly developed MSCs will be used as building blocks to realise on-chip power supply in conjunction with solar harvesters.

Welcome to Yifeng Fu, our new GreEnergy Project Coordinator

We are happy to welcome Dr. Yifeng Fu who has recently joined GreEnergy as project coordinator!

Dr. Yifeng Fu is associate professor in Chalmers University of Technology. His research interest is on micro-processing and nano-materials, including carbon nanotubes and nanofibers, graphene and related 2D materials, and nanoparticles for electronics applications.

In GreEnergy, Yifeng will be the intermediary between the consortium and the European Commission and will be responsible for EC reporting and the scientific coordination, ensuring productive collaboration between the consortium partners and successful progress of the project!

Discover the partner projects of GreEnergy

We are happy to present the Horizon 2020 funded projects WiPLASH and FOXES, as partner projects of GreEnergy in which AMO is also involved.

Key connections exist between GreEnergy and these partner projects, both in terms of technical challenges and commercial exploitation.

GreEnergy introduction to the Aachen Graphene & 2D Materials Center

On 15-16 November 2021, the members of the Aachen Graphene & 2D Materials Center met at RWTH Aachen University (Germany) for an internal workshop, to present and discuss the current research questions and challenges, as well as the latest results and key achievements.

During this workshop, Dr. Zhenxing Wang, leader of the Graphene Electronics group at AMO and WP leader in GreEnergy, gave a general introduction of the GreEnergy project to the audience via an invited talk.
