NOVEL COMPOUND-BASED SEMICONDUCTOR, A MANUFACTURING METHOD OF THE SAME, AND A THERMOELECTRIC CONVERTING ELEMENT AND A SOLAR CELL INCLUDING THE SAME CAPABLE OF FUNCTIONING AS THE LIGHT ABSORBING LAYER OF THE SOLAR CELL

摘要

PURPOSE: A novel compound-based semiconductor, a manufacturing method of the same, and a thermoelectric converting element and a solar cell including the same are provided to improve thermoelectric converting performance.;CONSTITUTION: A novel compound-based semiconductor is represented by chemical formula, In_xCo4Sb12-zTe_z. In the chemical formula, x is more than 0 and is less than or equal to 0.5, and z is more than 0.8 and is less than or equal to 2. A manufacturing method of the semiconductor includes the following steps: a mixture containing indium, cobalt, antimony, and tellurium is formed; and the mixture is thermally treated at a temperature between 400 and 800 deg C. The thermal treatment process is implemented using two or more kinds of thermal treatment techniques.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Comparative example 1; (BB) Comparative example 2; (CC) Comparative example 3; (DD) Comparative example 4; (EE) Example 1; (FF) Example 2; (GG) Example 3; (HH) Example 4; (II) Comparative example 5; (JJ) Comparative example 6
