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.
By controlling raw material stoichiometry and heating temperature in the synthesis of CaTiO3, the device shows the highest power conversion efficiency (PCE) of 2.12%, shortcircuit current density (JSC) of 0.027 mA cm-2, open circuit voltage (VOC) of 0.212 V and fill factor (FF) of 53.90%.
However, the natural shortcomings of solar irradiation including intermittence, volatility and unstable supply calls for the development of large scale, efficient and cost effective energy storage technologies, which becomes essential for massive uptake of the CSP technologies.
Therefore, Mn and Fe metal oxides, acted as high light-absorbing material, can effectively improve the optical absorption of the composites. Because the calcium-based composites need to be recycled in practice, it is important and necessary to understand the effects of thermal cycling on the optical absorption properties.
