The performance of a new dye-sensitized solar cell (DSSC) based in a natural dye extracted from the Bougainvillea spectabilis' bracts, is reported. The performance of this solar cell was compared with cells prepared using extract of the Bougainvillea glabra and mixture of both extracts; in both cases the pigments were betalains, obtained from Reddish-purple extract. These dyes were purified to different extents and used for the construction of solar cells that were electrically characterized. The materials were characterized using FTIR and UV-Vis. Solar cells were assembled using TiO(2) thin film on indium tin oxide (ITO)-coated glass; a mesoporous film was sensitized with the Bougainvillea extracts. The obtained solar energy conversion efficiency was of 0.48% with a current density J(SC) of 2.29 mA/cm(2) using an irradiation of 100 mW/cm(2) at 25 °C.
报道了一种基于从三角梅苞片提取的天然染料的新型染料敏化太阳能电池（DSSC）的性能。将这种太阳能电池的性能与使用光叶子花提取物以及两种提取物混合物制备的电池进行了比较；在这两种情况下，色素均为从红紫色提取物中获得的甜菜色素。这些染料被不同程度地纯化，并用于构建进行了电学表征的太阳能电池。使用傅里叶变换红外光谱（FTIR）和紫外可见光谱（UV-Vis）对材料进行了表征。太阳能电池是在涂有氧化铟锡（ITO）的玻璃上使用二氧化钛（TiO₂）薄膜组装而成；用三角梅提取物对介孔薄膜进行敏化。在25℃下，使用100 mW/cm²的辐照，获得的太阳能转换效率为0.48%，电流密度J(SC)为2.29 mA/cm²。
