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.
