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.
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.
