Disclosed is a dye, having a chemical formula: wherein each R1 is independently selected from hydrogen, —(CxH2x+1), —(CyH2y)—S—(CxH2x+1), or —(CyH2y)—N(CxH2x+1)2; Ar1 is wherein each R2 is independently selected from —(CxH2x+1), —(CxH2x)—S—(CxH2x+1), or (CxH2x)—N(CxH2x+1)2; Ar2 is wherein each R3 is independently selected from hydrogen, —(CxH2x+1), —(CyH2y)—S—(CxH2x+1), or —(CyH2y)—N(CxH2x+1)2; X is sulfur, oxygen, selenium, or N—R4, and R4 is —(CxH2x+1); m is in integer of 1 to 4; x is an integer of 1 to 20; and y is an integer of 0 to 20. The dye can be applied to a photoelectric conversion device.
