Improvement of dye-sensitized solar cells toward the broader light harvesting of the solar spectrum

다국어 초록 (Multilingual Abstract)

<P>Dye-sensitized solar cells (DSSCs) have been extensively evolved for the past two decades in order to improve their cell performance. From the commercialization point of view, the overall solar to electrical energy conversion efficiency should compete with other solar cells. But, due to structural restrictions of DSSC using the liquid electrolyte and a space requirement between two electrodes, the direct tandem construction of DSSCs by stacking of repeating units is highly limited. In this feature article, important research trials to overcome these barriers and a recent research trend to improve the light harvesting strategies mainly panchromatic engineering, various tandem approaches such as parallel tandem, series tandem, p–n tandem <I>etc.</I>, have been briefly reviewed.</P>

<P>Graphic Abstract</P><P>This article summarizes the effective utilization of solar energy using panchromatic engineering and various tandem structures in dye-sensitized solar cells.
