<P>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. <P>SOLUTION: A p-type semiconductor has composition represented by a general formula: (Cu<SB POS="POST">1-x</SB>Ag<SB POS="POST">x</SB>)<SB POS="POST">a</SB>Zn<SB POS="POST">b</SB>Sn<SB POS="POST">c</SB>S<SB POS="POST">d</SB>(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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
