PROBLEM TO BE SOLVED: To provide a new p-type semiconductor using a CZTS-system compound as a base, being low in cost, and having a relatively high conversion efficiency, and to provide a photoelectric element using the same.SOLUTION: A p-type semiconductor has composition represented by a general formula: (CuAg)ZnSnS(here, 0<x≤0.15, a<b+c, b>c, and a+b+c<d.), and contains a phase having a kesterite structure, and is used for a light absorption layer of a photoelectric element. A photoelectric element using the p-type semiconductor for the light absorption layer is also provided. In the general formula, x is preferably 0.025≤x≤0.10. |
