Report on preparation of the GQDs that functionalized with bulky functional groups

In order to target a concentration of 1-3 M of the nanoinks, the introduction of the bulky functional groups on the periphery of the GQDs will also be prepared.

Nanoinks with optimized properties

This deliverable deals with the the production of the fundamental materials and their hybrid coupling The materials will be produced in such a way that optical properties are optimized learning from the results from WP1

Report on preparation of the GQDs that functionalized with amino groups

In this deliverable GQDs with functionalized with amino groups will be prepared and optimzed towards their improved optoelectronic properties A major aspect will be to match the energy levels with the nanoparticles and to ensure stability in solution

Report on preparation of the GQDs that functionalized with pyrrole groups

In this deliverable GQDs with functionalized with pyrrole groups will be prepared and optimzed towards their improved optoelectronic properties. A major aspect will be to match the energy levels with the nanoparticles and to ensure stability in solution.

Dense nanoparticle inks

Densification of nanoparticle inks to 1-3 M is aimed and requires the work on the surface ligands or functional groups to ensure a stable solution while avoiding agglomeration. The stability in several different solvents as well as salts will be studied

Mesoporous structures and thin films

Thin films will be produced by deposition methods based on liquid processing from nanoparticle colloidal suspensions (spin coating, dip coating). Surface control of the nanocrystals and anchoring groups of the molecules are essential to obtain novel grafting methods. Mesoporous structures or thin films will be produced through aerosol methods or chemical deposition of pre-formed nano-species, respectively, in order to generate high porosity and specific surface area transparent photoactive materials with a tunable interface. Methods will be developed to incorporate plasmonic or photoactive species within the mesopores or locate them on the surface, in order to control electron flow or catalytic processes.

Hybrid interaction extracted

The optical properties of the prefabricated (nano)structures will be assessed by different spectroscopy techniques. Importance is devoted to the extraction of fundamental hybrid interaction at the liquid-liquid, liquid-solid and solid-solid interface. This task is of major importance as it will deliver the foundation for understanding multiple charge transfer reactions and their limiting factors. We will implement transient absorption spectroscopy with a temporal resolution from hundreds of femtoseconds to pico-, nano- and where necessary microseconds, to unravel charge carrier dynamics immediately after excitation with spectrally resolved probe to extract carrier relaxation pathways, timescales and efficiencies. These experiments will be performed on many different samples and hybrid combinations for a systematic understanding of the several different factors of materials, surfactants, functional groups, energy separation etc. influencing multiple charge transfer reactions. These results will be supported by several other complementary techniques, such as steady state UV-vis-NIR absorption/transmission and photoluminescence (PL) spectroscopy, scattering, dark field or confocal scanning microscopy, PL quantum yield, Raman spectroscopy/microscopy; as well as ultrafast measurements time resolved photoluminescence.

Optimized optoelectronic properties extracted

In order to proceed with the characterization of the electrodes their electric properties will be studied using various setups based on electrical probe stations operating in ambient condition and at low temperatures. These systems will allow the determination of various optoelectronic properties such as conductivity, photocurrent and detectivity, majority carriers and carrier mobilities, etc. To characterize the charge carrier injection properties in solution and solid-state we will combine spectroelectrochemical methods with common electrochemical tuning and several different optoelectronic tools such as (dark/illuminated) Kelvin Probe Microscopy, standard IV curves, impedance spectroscopy and CV curves etc.

Proof-of-concept light-driven single system multi-charge transfer electrolyte (only liquid)

The photoactive compartment will consist of a 0D NCPC-based electrolyte. The GQD dispersion acting as catholyte is selected on the basis of the optical photoelectrochemical performance elucidated in WP2. Such structures serve as first demonstrators for the light driven charge storage of multiple charges and will be coupled to respective counter electrodes and or proper electrolytes (see below).

Proof-of-concept light-driven single system multi-charge transfer electrodes (only solid)

The 0D NCPC-based electrode is coupled to a standard catholyte and standarad electrodes used to carry out the redox reactions in electrolytes based on redox active small organic molecules such as viologens, antraquinones, phenazynes, etc. The electrochemical measurements will be performed using potentiostat/galvanostat stations. The electrode/electrolyte couple of each cell compartment will be first investigated through cyclic voltammetry measurements in a three-electrode cell configuration using proper reference electrodes and counter electrodes, depending on the nature of the solvent of the electrolyte The polarization curve analysis will be performed on the whole cells under light in order to understand the rate capability of the energy storage.

Proof-of-concept light-driven hybrid multiple-charge transfer electrode (solid-liquid)

In the first flow cell architecture the 0D NCPC-based electrode is coupled to the GQDs dispersion (acting as the catholyte). The other compartment will be based on electrodes used to carry out the redox reactions in electrolytes based on redox active small organic molecules such as viologens, antraquinones, phenazynes, etc. This will be assembled to photo-electrochemical H-cell with electrolyte input/output ports, as well as compact no-gap serpentine architecture. The polarization curve analysis will be performed on the whole cells under light in order to understand the rate capability of the energy storage. High-frequency resistance of the system will be measured by electrochemical impedance spectroscopy to exclude possible series resistance effects, thus determining iR-corrected polarization curves specifically resulting by kinetic losses. Galvanostatic charge discharge measurements of the systems will be carried out at different current densities, which will be selected on the basis of the polarization curve results. Solar-driven charge will be investigated by coupling a light source to the flow cell and illuminating the transparent electrode while monitoring the obtained photocurrent and photovoltage. Experiments with electrolytes having different concentration of redox-active materials and being initially charged at different states of charge (SOC) will be performed to investigated the efficiency of the solar-driven flow batteries as a function of the electrolyte composition. The light storage efficiency will be calculated as the ratio between the stored energy density in the system and the energy of the incident light. Additionally, coulombic efficiency (i.e., the ratio between discharge capacity and the charge capacity), the voltage efficiency (i.e., the ration between the average voltage during discharging and the average voltage during charging), as well as the energy efficiency (i.e., the product between the coulombic efficiency and the voltage efficiency), will be determined by the charge/discharge curve analysis. For the overall flow-driven system, the “overall” energy conversion efficiency will be determined by the product between the charge storage efficiency and the energy efficiency. In order to observe the intrinsic properties and electrode performance, it is essential to elucidate the electron transport at the electrode/nanomaterial interface for examples by using local AFM based technologies. We will additionally implement nanomanipulators to extract the electronic characteristics and any other microscope to study very locally and with micrometer precision the device characteristics. Lastly, AFM mapping of electrical analysis, such as I-V curves and impedance spectroscopy will additionally give information on the electrode characteristics. Long-term experiments will be performed by galvanostatic experiments
