Laboratory of Molecular Research for Solar Energy Innovations


Research interests of SOLEIL Group focus on design, synthesis & application of nanomaterials and advanced architectures for solar energy technologies and photo-driven biocatalytic  applications. However, now, it starts to be obvious that with deep knowledge on synthesis and functionalization of metal oxide nano-architectures for solar energy conversion we can start to ask new questions about underlying understanding of elementary chemical reactions and photoelectrochemical processes and finally address them by new ultrafast spectroscopic and in-situ conceptual techniques allowing to directly investigate charge transfer kinetics phenomena  We believe, that this conceptual approach to the molecular systems to identify the major bottlenecks hampering the efficiency of current solar systems has a bright future.

Research Topics:

Investigation of the combined electro-photo-reduction of CO2 at selected catalysts  taking in parallel, profit from the extra activation of the process provided by the plasmonic nanostructures

Identification and recognition of the kinetic processes governing the performance of the earth abundant materials and their integrated systems with use of the ultrafast TAS approach (combined charge carrier dynamics & kinetic analysis)

Identification & synthesis of radically new photoactive materials

Design, construction & understanding of a sensing mechanism of the photoelectrochemical biosensors based on the polycrystalline semiconductors and demonstrate a proof of concept through the quantification of the biosensing activity and efficiency of the overall PEC sensor for a number of selected bioanalytes.

Project title: HERA (Hydrogen Energy Rechargable Architectures): Coupling of on-demand hydrogen generation and storage

Implementation in a consortium: Uniwersytet Warszawski, CeNT dr hab. Renata Solarska coordinator
InPhoCat Kraków Firma technologiczna

Source of funding: NCBiR (Norwegian funds)

Total budget: 6 475 885 PLN

Project duration: 01.07.2020 – 01.07.2023

About the project:
The HERA project has an ambition to bring knowledge on the “solar hydrogen” production & storage closer to the users and, via technological optimization, translate it to a product. This goal will be achieved by integrating lab-scale studies with system-oriented experimental examinations, yet unapplied to the compounds/composites proposed in HERA. The current systems for the “solar hydrogen” production consume excessive amount of energy, to overcome the oxygen kinetic-related overpotential, and cannot provide enough power in an economically feasible way. Also, they do not include the storage option for the produced hydrogen. Therefore, the main HERA’s goal is to construct a kinetically enhanced PEC device that will provide the absorption of the produced H2 in the cathode material. The proposed setup will also allow for the on demand release of the absorbed gas. The photooxidation reaction will be the driving force of the planned architecture. It will involve other than water oxidation processes that are expected to provide enough electrons for the water reduction, hydrogen formation and its subsequent absorption by the cathode. The latter will be realized by application of metal hydrides as a hydrogen storage medium. In HERA, we will focus on the investigation of A2B7- and AB-type alloys, in view of their versatility for the PEC hydrogen production and storage. The research will to go far beyond single case examples and cover systematic investigations of multi-substituted compositions, underlying the relationship between the fundamental material properties and functionalities in the studied photoelectrochemical architectures. We expect that HERA achievements will contibute to breakthroughs in the field of design and applications of the environment-friendly and economically viable renewable energy-based technologies.
