M2i Meeting Materials 2020 - Materials for Energy

As part of the M2i conference Meeting Materials 2020, the 4TU.Research Centre High-Tech Materials organizes a session on Materials for Energy.

This means that, for the second time, the annual 4TU.HTM symposium 'Dutch Materials' - as held in 2016, 2017 & 2018 - will be part of the M2i conference Meeting Materials.

In 2019, 4TU.HTM has been organizing two sessions on Education in Materials Science at the M2i Meeting Materials 2019 conference.

At the public oline M2i Meeting Materials conference 2020, 4TU.HTM will organize a session on Materials for Energy.

Materials for Energy

Aim

The aim of this session is to bring together scientists with interest and expertise on materials for energy, for an exchange of ideas and observations. With this session, we emphasise the importance of materials for the development of sustainable energy conversion and storage. The focus of the presentations is on materials for solar and wind energy, materials for hydrogen storage and batteries and materials for CO2 conversion.

Title: Vacuum-deposited halide perovskites and broadband transparent conductive oxides for photovoltaics - Abstract  (Pdf file)

Abstract
Pulsed Laser Deposition (PLD) has offered unique options for the development of complex oxides growth, allowing multi-compound deposition independent of the relative volatility of the elements and ultimate control of interfaces. In this presentation we discuss the rather unexplored but great potential of PLD for: 1. The implementation of broadband transparent electrodes on top of sensitive solar cell absorbers. 2. The single-source deposition of halide perovskite thin films for solar cells and beyond.

In the first part of the presentation we discuss recent developments and application of high-performance TCOs, with a special focus on Zr-doped indium oxide (IZrO), a promising broadband transparent and conducting oxide for perovskite-silicon tandem solar cells [1-3]. We demonstrate PLD-grown IZrO rear electrode on semitransparent halide perovskite solar cells resulting in reduced damage of sensitive electron transport layers and an improved stabilized efficiency of 15.1%. In the second part, we discuss the recent progress on the growth of hybrid and inorganic halide perovskites by PLD with focus on target preparation and optimization of PLD parameters to achieve optimum control on polymorph formation and optical properties[4]. All these are important steps forward in the controlled growth and future scalability of optoelectronic materials for efficient devices such as solar cells and LEDs.[5]

Title: Hydrogen as an energy carrier: a materials perspective



Using hydrogen as an energy carrier is an attractive alternative to fossil fuels. Hydrogen has a high energy content per mass, can be produced in many ways and is a suitable means to store and transport energy. Today however still 95% of the hydrogen produced is from fossil fuels. The most cost-effective production of hydrogen is through the water-gas shift reaction of natural gas. Using metal-membrane reactors makes this process energy-efficient, and by combining it with CO2-capture greenhouse gas emission is prevented. To obtain suitable and stable membranes, Pd-based alloys with appropriate composition and microstructure are designed. Also in H-sensors and storage the interaction of hydrogen with Pd plays a key role.  Various aspects of H-metal interaction will be discussed in relation to a (partially) hydrogen-based economy.

Title: Bottom-up design of electrodes for redox flow batteries






Abstract
Redox flow batteries (RFBs) are promising rechargeable electrochemical devices for grid-scale energy storage, but further cost reductions are needed for widespread implementation. While research efforts have primarily focused on molecular discovery, there has been significantly less attention paid to the engineering aspects (i.e. transport phenomena, reactor design) of the battery. Of particular importance are the porous electrodes used in the electrochemical stack, which are typically made of carbon fibers arranged in various structures. Today’s electrodes largely draw from the fuel cell material set, but, within a RFB, the porous electrode must perform a number of different roles including providing active surfaces for electrochemical reactions, facilitating uniform liquid electrolyte distribution, and supporting low pressure drops.  In this talk, I will discuss our efforts to understand the role of electrode microstructure on the performance of RFBs using experimental techniques and simulations. Finally, I will discuss alternative approaches to bottom-up engineer porous electrodes with controlled microstructures.

Title: Electrocatalytic materials for CO2 conversion to fuels and bulk chemicals


Abstract
Increasing CO2 concentrations in the atmosphere are an issue of global concern, as CO2 is a major contributor to the greenhouse effect. Electrocatalytic reactions provide an unique approach to utilize renewable electricity to produce renewable fuels and bulk chemicals for the chemical industry. For instance, the electrochemical reduction of CO2 can utilize CO2 as a carbon feedstock to produce commodity chemicals or fuels. However, the lack of stable electrocatalysts that can selectively and energy efficiently produce commercially interesting chemicals is holding back the large-scale deployment of this technology. In this talk I will provide an overview of our group’s activities on the development of more efficient electrocatalytic materials for CO2 conversion. I will highlight recent examples of bimetallic and carbon-based electrocatalytic materials for the electrochemical reduction of CO2 to valuable products.
