Materiales Avanzados para la Energía

The area of Advanced Materials for Energy is a unit of research and technological development focused on materials for the conversion and storage of energy. Its activities involve the transfer of scientific and technological knowledge to industry and offers, at the same time, technological support for addressing innovations in this field. This activity is strongly related to the activities of research and technology development in other areas of the Institute, where projects are boosted through collaboration.

With regard to energy conversion, the work of the Advanced Materials for Energy area is mainly focused on solar energy, including different options for the direct conversion of solar energy into electrical energy and/or chemical energy. Besides photovoltaic systems, there are different technological approaches, and activities cover other mechanisms of conversion based on nanomaterials and nanotechnologies. Their performance is investigated for application in thermoelectric and thermionic systems, and nanoionic properties are being studied for new electrochemical systems, while nanocatalyts are being implemented for new energy conversion systems and the relevant advances in nanoelectrochemistry are being used for improved energy storage cells.

In this field of research, the main challenges for scientific breakthroughs in new materials and devices are framed within the cost needs for the energy obtained and its compatibility with the use of sources distributed in buildings, cities and energy production plants.

In this context, our activities with photovoltaic energy are centred on thin layer technology II-VI and the use of new concepts in nanomaterials to increase efficiency and/or reduce cost. At the same time, our capacity to synthesize and/or grow new nanostructured materials as well as new catalysts is addressed to new concepts of photoelectrochemical systems for the direct conversion of solar energy into chemical energy and new methods to make use of thermoionic and thermoelectrical conversion. Regarding photoelectrochemical conversion, or artificial photosynthesis, our objectives are to obtain hydrogen and reduce CO2 to develop a C1 economy with special attention to the storage of chemical energy. These activities are also guided by new discoveries in the field of nanoionics for the advancement of electrochemical systems such as fuel cells and their reversible use as electrolysers.

Likewise, the activity in new 3D electrodes based on advanced nanomaterials and the use of catalysts, membranes and new formulations of liquid electrolytes is being applied to the development of new technologies for electrical storage beyond the present battery technology as well as new methodologies for the diagnosis and prognosis of energy storage systems.

The above activities are focused on convergence for the development of integrated systems, their control, and development of testing tools. Their control by means of sensors and the use of harvesting tools allows us to guarantee sustainable autonomy, and potential effects on energy management criteria.

The Advanced Materials for Energy area is organized in five interrelated laboratories and a general laboratory of common services and facilities. These laboratories are respectively focused on the following main activities:

a) Functional Nanomaterials

b) Materials and Catalysis

c) Solar Energy Materials and Systems

d) Nanoionic and fuel cells

e) Energy storage and energy harvesting

Functional Nanomaterials

The research and technological activity of the FNG has been focused on the production of new nanostructured materials, their structural, chemical and functional characterization, and their use in photovoltaic, thermoelectric and catalytic applications. The following are the current main research lines of the FNG:

  • Preparation and characterization of functional nanomaterials
  • Functionalization and self-assembly/deposition of colloidal nanocrystals
  • Fabrication and characterization of nanomaterials-based devices for energy conversion and storage: Photovoltaics, thermoelectrics and catalysis.

Materials and Catalysis

This group’s activity involves the development and application of new catalysts for energy conversion reactions and for the transformation of chemical-based energy carriers. The capacity for synthesis, structural characterization and functional assessment of the developed catalyst using reactor prototype is also available.

The main activities are centered on bioalcohol and biomass transformation and reforming, hydrogen production and on the production of fine chemicals from CO2, contributing to the development of the C1 economy by applying heterogeneous catalysis based on the development of advanced active multi-catalysts and supporting nanostructures.

Reactor prototyping is applied for laboratory scale assessments although scale-up procedures are also considered for pilot plants.

Solar Energy Materials and Systems

The Group of Solar Energy Materials and Systems is focused on the development of new materials and processes for advanced thin film PV technologies compatible with the requirements of sustainability and compatible with industrial mass-production with very low environmental impact, high efficiency and low manufacturing cost. These are the main challenges facing PV technologies in order to respond to increasing social and industrial demands to become real alternatives to conventional non-renewable energy technologies. With this main goal, the Group has been very active in the development of thin film technologies based on inorganic chalcogenide compounds, including technologies that are beginning their industrial implementation stage – like those related to Cu(In.Ga)(S,Se)2 (CIGS)- as well as emerging technologies based on new materials such as kesterite (Cu2ZnSn((S,Se)4 (CZTS)) compounds, as well as in the research and development of advanced characterisation tools suitable for quality control and process monitoring.

Nanoionic and fuel cells

The group is focused on fundamental and applied research in ionic/electronic conductor materials for energy applications. Technology transfer is one of the main goals of the group facing the implementation of new materials in new devices and the optimization of familiar technologies through newl approaches. The research and technological activity developed in the NFC group can be divided into two main lines:

-Nanomaterials for energy (micro) systems.
-Solid Oxide Cells (SOC).

Singular nanofabricaton equipment such as large area PLD with combinatorial facilities or wafer-level CVD for nanowires growth are combined with flexible automatic test stations for the electrochemical and electrical characterization of microdevices (micro-SOFC, thermoelectric micro harvesters and micro gas sensors) and SOCs (materials, button cells and small stacks working in power generation and electrolysis mode).

Energy storage and energy harvesting:

Activities are focused on the development of materials and device technologies required for implementing new advances in energy storage systems and their field demonstration for large and intermediate energy storage systems related to renewal and distributed energy sources. The main actions are mainly addressed to electrical storage systems based on liquid electrolyte, flow redox and metal air batteries as well as chemical storage.

New 3D electrodes, membranes and liquid electrolyte are developed, tested and evaluated using our self-made battery cell technology that has been adapted for flow redox battery as well as for new photoelectrochemistry cell. Materials, catalysts and devices/photoreactors are being developed for it, and experimentally implemented and checked for artificial photosynthesis and solar fuel production (hydrogen, CO2 reduction, syngas, methane and methanol).

On the other hand, the laboratory is launching activities or developing improved materials for energy harvesting elements for biasing sensor systems required for monitoring and controlling energy production plants, distribution grids, energy consumption and efficiency in buildings, environments and improving system sustainability, etc
