Abstract

Trollius chinensis pigment was extracted, and ultraviolet-visible (UV-Vis) absorption and Fourier transform infrared (FTIR) spectroscopy confirmed that anthocyanin compounds were the main components. Dye sensitized solar cells (DSCs) were sensitized from the natural pigments dissolved in different pH solutions. Open-circuit voltage increased with increasing pH,while short-circuit current density first increased and then decreased, attributed to an anthocyanin structural change with pH value. The highest observed power conversion efficiency was 0.292% at pH=5.
