Zusammenfassung:	The present invention relates to a metal calcogenide nanoparticle and a method for manufacturing the same. A metal calcogenide nanoparticle for forming the light absorption layer of a solar cell includes at least two phases selected from a phase made of Ga-containing calcogenide, a second phase made of In-containing calcogenide, a third phase made of Ga and In-containing calcogenide, and a fourth phase made of Cu-containing calcogenide. 본 발명은 태양전지의 광흡수층을 형성하는 금속 칼코게나이드 나노 입자로서, 갈륨(Ga) 함유 칼코게나이드로 이루어진 제 1 상(phase), 인듐(In) 함유 칼코게나이드로 이루어진 제 2 상(phase), 갈륨(Ga)과 인듐(In)을 모두 함유하는 칼코게나이드로 이루어진 제 3 상(phase), 및 구리(Cu) 함유 칼코게나이드로 이루어진 제 4 상(phase)으로부터 선택되는 둘 이상의 상들(phases)을 포함하는 것을 특징으로 하는 금속 칼코게나이드 나노 입자 및 이의 제조 방법에 관한 것이다.
