Calorimetric Determination

The calorimetric determination of the standard enthalpy of formation of Cu2FeSnSe4 selenium stannite (CITSe) was carried out for the first time. This compound in its pure form does not occur in nature, but is a promising functional material (direct-gap semiconductor) and is used in photovoltaics to create solar cells as an alternative to silicon. The standard enthalpy of Cu2FeSnSe4 formation was obtained by measuring the heat of its formation from the elements in the calorimeter according to the reaction 2Cu + Fe + Sn + 4Se Cu2FeSnSe4. As a result, the standard enthalpy of formation is detrmined: ∆fH0298.15K(Cu2FeSnSe4) = (254.11 3.96) kJ/mol.
