Simultaneously harvesting, converting and storing solar energy in a single device represents an appealing technological approach for the next generation of power sources. Herein, we propose a device consisting of a single piece of (rhenium, Re; niobium, Nb) doped WSe2 photocathode and zinc foil anode system capable of harvesting solar energy (and converting it into electricity) and a rechargeable aqueous zinc metal cell. The proposed cell demonstrated an improvement in the specific capacitance of around 45% under visible light irradiation. Also, Re doped WSe2 exhibited a loss of 4.44 % at its initial specific capacitance after 500 galvanostatic charge-discharge cycles at 50 mA g-1. As a result, the device delivered a specific energy density of 574.21 mWh Kg-1 at a power density of 5906 mW Kg-1 and at 0.015A g-1. Furthermore, the notable enhancement in capacitance achieved through the Re-WSe2 photo-zinc ion capacitor (photo-ZIC) offers a straightforward and constructive avenue to establish a cost-effective and highly efficient solar-electrochemical capacitor system.
The research leading to these results was supported by the the Johannes Amos Comenius Programme, European Structural and Investment Funds, project 'CHEMFELLS V‘ (No. CZ.02.01.01/00/22_010/0003004).
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
