SORBENT OF SEPARATING AND PURIFING NATURAL DYE FOR DYE-SENSITIZED SOLAR CELLS

摘要

The present invention relates to an adsorbent for separation and purification of a natural dye used in a dye-sensitized solar cell. The adsorbent for the natural dye is composed of a nonionic polymer resin with a porous network structure. In addition, a desorbent used for desorption of a target component from the nonionic polymer resin can be one selected among water, an organic solvent, or a water-organic solvent, wherein the organic solvent is ethanol.
