New PhD opportunities through INPhINIT Fellowships funded by La Caixa (2)
Solar Flow Batteries (SFBs) are a new type of devices that integrate solar energy conversion and electrochemical storage. The operation principle of SFBs is built on the working mechanism of RFBs and photoelectrochemical (PEC) cells. In SFBs, the solar energy absorbed by photoelectrodes is converted into chemical energy by charging up redox couples dissolved in electrolyte solutions in contact with the photoelectrodes. To deliver electricity on demand, the reverse redox reactions are carried out to release chemical energy stored in redox couples as one would do in the discharge of a normal redox flow battery (RFB). Well-designed, SFBs could represent a more cost-effective, efficient, and compact approach for stand-alone off-grid electrification, such as solar home systems in remote or rural areas.
This research project will address the following interconnected aspects: (1) Developing compatible and energy level matching photoelectrode materials and redox electrolytes to maximize the photocharging efficiency (i.e. solar-to-chemical efficiency, STC%), (2) full characterization of redox couples and photoelectrodes, (3) understand the fundamental aspects of interfaces between the photoelectrode and the redox electrolyte under illumination, and (4) design and testing of SFB devices.
RESEARCH GROUP DESCRIPTION
This project is envisaged as a joint endeavor between two research units of IMDEA Energy; the Electrochemical Processes Unit with a proven experience on the development of RFB, and the Photoactivated Processes Unit with a strong background on Photo and Photo-electrochemical processes. In particular, both supervisors hold ongoing ERC-Consolidator Grants on Redox Flow Battteries (MFreeB / R.Marcilla) and Photoreduction processes (HyMAP / V. de la Peña O’Shea). This PhD project will take advantage of the solid background of both groups and will gather together the most recent achievements in RFB and photoelectrode to make a big contribution in the nascent field of Solar Flow Batteries
JOB POSITION DESCRIPTION
The main objective of this PhD project is the development of efficient Solar Redox Flow Batteries able to be charged with solar light by means of photoelectrodes which absorb the incident solar energy and transfer the generated electrons to charge up redox couples in the electrolytes. The development of compatible photoelectrodes and redox electrolytes and the design and testing of SFBs will be key activities of this PhD project.
