Abstract
Conventional optoconductive compounds, such as CIS or CdTe include scarce indium or environmentally-unfriendly cadmium. On the other hand, an optoconductive compound according to the present invention has high optoconductive efficiency without inclusion of indium and cadmium, wherein the optoconductive compound according to the present invention is represented by AXYY′ where A is a Group 11 element, X is a Group 15 element, and Y and Y′ are Group 16 elements in which Y and Y′ can be identical to or different from each other.
Claims6
A method of producing an optoconductive compound, the method comprising:
- depositing a first material represented by X2Y3 on a substrate;
- depositing a second material represented by AY′2 on the first material;
- and
- performing a heat treatment on the first material and the second material, wherein A is a Group 11 element, X is a Group 15 element, and Y and Y′ are Group 16 elements, wherein Y and Y′ can be identical to or different from each other.
