Abstract

In the last years, the growing attention towards environmental sustainability and circular economy has led to a renewed interest in the use of eco-friendly and recyclable materials in various sectors.

Developing innovative dye sensitized solar cells (DSSCs) based on microbial pigments, is very important to meet the demands of sustainable devices. Microbial extracts obtained from Talaromyces atroroseus GH2, Arthrobacter bussei CP30 and Paracoccus bogoriensis BOG6 cultivations, and characterized by HPLC-DAD-ESI-MS analyses, have been used in this work for this purpose. The extracted pigments were tested to evaluate their suitability as photosensitizers through co-sensitization method. UV–vis measurements were carried out to determine the absorbance intensity, while Photoelectrochemical and Electrochemical Impedance Spectroscopy (EIS) analyses were applied to evaluate the devices' photovoltaic parameters and impedance characteristics. The best device, obtained by the co-sensitization of the dyes produced by Talaromyces atroroseus GH2/Paracoccus bogoriensis BOG6, exhibited a Jsc of 1.59 mA/cm², Voc of 0.35 V, FF of 0.62, and a PCE of 0.34 %. This study highlights the potential of microbial-derived pigments in the development of DSSCs.

基于天然微生物颜料共敏化的创新型染料敏化太阳能电池（DSSC）的开发

近年来，人们对环境可持续性和循环经济的关注与日俱增，促使各行各业重新关注生态友好型可回收材料的使用。为此，本研究采用了从 Talaromyces atroroseus GH2、Arthrobacter bussei CP30 和 Paracoccus bogoriensis BOG6 培养物中提取的微生物提取物，并通过 HPLC-DAD-ESI-MS 分析对其进行了表征。通过共敏化法对提取的色素进行了测试，以评估它们作为光敏剂的适用性。紫外-可见光测量用于确定吸光强度，而光电化学和电化学阻抗光谱（EIS）分析则用于评估器件的光电参数和阻抗特性。由 Talaromyces atroroseus GH2/Paracoccus bogoriensis BOG6 产生的染料共同敏化得到的最佳装置的 Jsc 为 1.59 mA/cm2，Voc 为 0.35 V，FF 为 0.62，PCE 为 0.34 %。这项研究凸显了微生物衍生色素在 DSSC 开发中的潜力。

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
