Abstract: The present disclosure relates to a microneedle array-based electrode comprising organic photovoltaic substances, and an artificial retina device comprising the same, and the microneedle array-based electrode is coated with, as organic photovoltaic substances, a mixture of PCE10, which exhibits the highest absorbance in infrared rays, and ITIC, thereby exhibiting excellent photovoltaic efficiency and low phototoxicity. Further, since an artificial retina device comprising the electrode can adjust the generation of current only with light without any wire connecting the inside and outside of the eyeball, it is possible to restore nerve signals by stimulating the retina of a patient whose photoreceptor cells are damaged.
