Abstract

In the context of increasing the use of sustainable materials derived from renewable, non-toxic, and biocompatible sources, dyes obtained from microorganisms have garnered significant interest, particularly for clean energy applications. This study presents a novel comparison of astaxanthin produced from three different microbial sources for dye-sensitized solar cells (DSSCs) to evaluate their photovoltaic performance. Comprehensive characterization using multiple analytical techniques (HPLC-DAD-APCI-MS, UV–vis spectroscopy, scanning electron microscopy (SEM), IV measurements, and electrochemical impedance spectroscopy (EIS)) were carried out on pigments extracted from the microalga Haematococcus pluvialis, the yeast Phaffia rhodozyma, and the bacterium Paracoccus carotinifaciens to highlight the structural differences that influence the dyes’ photoelectrochemical behavior. The results show that the DSSC based on the extract from Paracoccus carotinifaciens demonstrated the highest efficiency, recording a short-circuit current density (Jsc) of 2.86 mA/cm², an open-circuit voltage (Voc) of 0.419 V, a fill factor (FF) of 0.3, and a power conversion efficiency (PCE) of 0.36 %.

微生物源对染料敏化太阳能电池（DSSC）中作为敏化剂的虾青素的影响

在越来越多地使用可再生、无毒和生物相容性材料的背景下，从微生物中获得的染料引起了人们的极大兴趣，尤其是在清洁能源应用方面。本研究对从三种不同微生物来源生产的染料敏化太阳能电池（DSSC）虾青素进行了新颖的比较，以评估其光伏性能。采用多种分析技术（HPLC-DAD-APCI-MS、紫外-可见光谱、扫描电子显微镜（SEM）、IV 测量和电化学阻抗光谱（EIS））对从微藻类 Haematococcus pluvialis、酵母 Phaffia rhodozyma 和细菌 Paracoccus carotinifaciens 中提取的色素进行了综合表征，以突出影响染料光电化学行为的结构差异。结果表明，基于 Paracoccus carotinifaciens 提取物的 DSSC 效率最高，短路电流密度 (Jsc) 为 2.86 mA/cm2，开路电压 (Voc) 为 0.419 V，填充因子 (FF) 为 0.3，功率转换效率 (PCE) 为 0.36 %。

期刊介绍： JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds. All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor). The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
