Investigating of Colorimetric Characteristics of Anthocyanin Dyes Applied in Dye-Sensitized Solar Cells

Today, attention is paid to clean solar energy to reduce fossil fuel pollution. Dye-sensitized solar cells (DSSCs) convert light energy into electrical energy. One of the important components of DSSCs is the dye. Natural dyes are very convenient because of their low cost and ease of access. For this end, 9 natural dyes based on anthocyanin were selected and employed in DSSCs structure. For the first time, the reflection diagrams, CIELAB and CIELCH color spaces were achieved to study the color behavior of natural dyes applied in DSSCs. According to the results, the natural dyes applied in DSSCs structure have different color and lightness. Besides, the color gamut volume of anthocyanin based natural dyes applied in DSSCs was computed about 2.67 ×104 using well-known algorithm.
