文摘
In this work, we study the characteristics of dye-sensitized solar cells using an ionic liquid as the electrolyteand compare them with the response of a solvent-containing electrolyte cell. Impedance spectroscopy is usedto derive the key circuit elements determining the photovoltaic performance of the cell. On the basis of thisdata, photocurrent voltage curves are calculated and compared with experimental results.
