Electrodeposited thin-film Cu-Zn-Sn samples were reacted in varying ratios of mixed Ar/H2S/H2Se to form Cu2ZnSn(S,Se)4 (CZTSSe). Reactions were carried out at atmospheric pressure, reaching a temperature of 550 C. Sulfur/selenium ratios in reacted films were determined as a function of / in the reaction atmosphere. Relative S/Se incorporation into the CZTSSe films was used

Prediction of the effective thermal conductivity of packed

The heat transfer property of the powder bed greatly affects the performance of a thermochemical heat storage system. Therefore, an accurate evaluation of effective thermal conductivity (ETC) is a key for developing thermochemical heat storage systems. This paper focuses on the ETCs of commonly used porous thermochemical materials, such as MgO/Mg(OH)sub2/sub and

Impact of Partial Pressure, Conversion, and Temperature on

Metal oxides are promising potential candidates for thermochemical energy storage in concentrated solar power plants. In particular, the Cu2O/CuO system is suitable because of its high energy density, applied temperature interval, and reduced cost compared to the CoO/Co3O4 system. In heterogenous gas-solid reactions, the pressure affects the kinetics significantly.
