Conclusions This work analyzes the multicycle activity of CaO derived from diverse natural CaCO 3 minerals (limestone, chalk and marble) at optimum Calcium-Looping conditions for the thermochemical storage of energy in Concentrated Solar Power plants.
Herein calcium titanate (CT) as a lead-free perovskite material were synthesized through sintering of calcium carbonate (CaCO3) and titanium oxide (TiO2) by the sol-gel method. CT powders were characterized by SEM, XRF, FTIR and XRD then applied it onto the mesoporous heterojunction PSCs, with a device architecture ITO/TiO2/CaTiO3/C/ITO.
Hanawa et al. experimented and reported that titanium plates when immersed in the calcium ion-containing solutions, including calcium nitrate, calcium chloride, and calcium oxide solution, at ambient temperature for 7 days, formed a surface-modified layer consisting of calcium hydroxide and/or calcium titanate on their surface.
Briefly, once CaCO 3 particles are calcined by concentrated solar irradiation, the products of the reaction (CaO and CO 2) are stored separately. When needed, these byproducts are brought together at carbonation conditions to use the heat from this exothermic reaction to produce electricity.
This potential leads to the self sustaining energy possibility fulfilling the electricity needs. Due to their unique electronic structures and high cost merit over the existing commercial PV technologies, perovskite solar cells (PSCs) have emerged as the next-generation photovoltaic candidate.
The calcium ion implantation process was developed by Hanawa et al. . This process forms a continuous interface between the surface-modified layer and substrate, which was expected to prevent the interface fracture.
