摘要

染料敏化太阳能电池已被证明是一种前景广阔的能源转换技术。它由支架材料、电解质、对电极和光敏分子组成。由于最常用的钌有机材料成本高昂,人们开始合成新的化合物以降低成本。本研究介绍了(E)-4-(4-羟基-3-甲氧基苯基)丁-3-烯-2-酮(1)的合成和应用,它是姜黄素的单羰基类似物,可用作光伏系统中的光敏材料。研究人员以化合物 1 增敏的二氧化钛为支架材料,以石墨烯为对电极,以 I-/I3- 为电解质制备了装置。结果表明,使用新型有机材料可以提供高效的能量转换装置,其参数为:Jsc = 0.31 mA cm-2;Voc = 0.54 V;FF = 0.47;PCE = 0.07%;\(\tau_{n}\) = 0.637 s。

Fabrication of a dye sensitized solar cell using TiO2 sensitized with a mono-carbonyl curcumin analog

Dye sensitized solar cell has been shown to be a promising technology for energy conversion. It presented in composition a scaffold material, an electrolyte, a counter electrode and a photosensiting molecule. Due to the costs of the most applied ruthenium-organic material, new compounds are synthesized with the aim of reducing costs. This work describes the synthesis and application of (E)-4-(4-hydroxy-3-methoxyphenyl) but-3-en-2-one (1), a monocarbonyl analog of curcumin, as a photosensiting material in a photovoltaic system. Devices were prepared using TiO2 as scaffold material sensitized with compound 1, graphene as a counter electrode, and I/I3 as an electrolyte. The results showed the possibility of using new organic materials, providing an efficient device in energy conversion, with parameters of Jsc = 0.31 mA cm−2; Voc = 0.54 V, FF = 0.47, PCE = 0.07% and \(\tau_{n}\) = 0.637 s.
