Naturally abundant dyes are very attractive for the development of dye-sensitized solar cells (DSSCs). Hydroxycinnamic acid derivatives, such as caffeic acid (CA), ferulic acid (FA), and p-coumaric acid (PA), were considered for the selective harvesting of ultraviolet A (UVA) (315-400 nm) photons. Their spectroscopic and electrochemical properties were investigated both theoretically and experimentally. They were further successfully adopted as photosensitizers in UV-selective and visibly transparent DSSCs, which exhibited a power conversion efficiency of 0.22-0.38% under AM (air mass) 1.5G (global) illumination (100 mW/cm) and 3.40-3.62% under UVA irradiation (365 nm, 115.22 mW/cm), with a corresponding visible light transmittance (VLT) of 49.07-43.72% and a general color rendering index (R) of 93-90.
天然存在的染料非常适合用于开发染料敏化太阳能电池 (DSSC)。羟基肉桂酸衍生物，如咖啡酸 (CA)、阿魏酸 (FA) 和对香豆酸 (PA)，被认为可以选择性地收集紫外线 A (UVA) (315-400nm) 光子。它们的光谱和电化学性质在理论和实验上都进行了研究。这些化合物进一步成功地被用作紫外光选择性和可见光透明 DSSC 的敏化剂，在 AM1.5G（全球）照明（100mW/cm²）下的功率转换效率为 0.22-0.38%，在 UVA 辐射（365nm，115.22mW/cm²）下的效率为 3.40-3.62%，相应的可见光透过率 (VLT) 为 49.07-43.72%，整体显色指数 (R) 为 93-90。
