Abstract
A poly cross linked phthalocyanine compound for a solar cell and ink composition comprising the same, and more particularly a poly cross linked phthalocyanine compound effective for use in a near infrared absorbent having a high absorption power in a near infrared wavelength from about 750 nm to about 1100 nm, wherein the poly cross linked phthalocyanine compound having structures according to the present inventive concept is sensitized to infrared region, although ruthenium-based compound used for existing dye-sensitized solar cells is sensitized to visible light region, such that the compound according to the present novel concept can be extended in wavelengths for use in solar cells to improve an energy conversion efficiency.
