Abstract

Anthocyanin-enriched dye is extracted from the fruits of blueberry using ethanol, and citric acid is added to enhance the acidity (pH = 3 and 5) in the photoanode of DSSC, is serves as the sensitizer. Organic additive in the dye solution has enhanced the efficiency of dye dye-sensitized solar cell to a larger extent. Henceforth, the dye solution with a pH of 1(raw), followed by pHs of 3 and 5 with the addition of citric acid, is subjected to FTIR, UV–Visible, and PL spectroscopic studies. The photoanode of the TiO₂-coated FTO substrate is soaked with the dye solution having a pH of 5, redox couple electrolyte of I⁻/I₃⁻, and the counter electrode of graphite coated over FTO is sandwiched to fabricate the DSSC. The cell is subjected to JV characterization for the determination of cell parameters, in which it has produced an efficiency of 2.152% with open circuit voltage, short circuit current density, and fill factor of 1.006 V, 3.0507 mA/cm², and 0.701, respectively.

蓝莓果实花青素增敏剂在dssc光阳极中的应用——一个广泛的实验分析

利用乙醇从蓝莓果实中提取富含花青素的染料，并在DSSC光阳极中加入柠檬酸增强酸性（pH = 3和5），作为增敏剂。染料溶液中的有机添加剂在较大程度上提高了染料敏化太阳能电池的效率。因此，对pH为1（原始），pH为3和5（添加柠檬酸后）的染料溶液进行了FTIR， uv -可见和PL光谱研究。用pH为5的染料溶液、I−/I3−氧化还原偶电解质浸泡tio2 - FTO衬底的光阳极，并将涂覆在FTO上的石墨对电极夹在中间制备DSSC。对该电池进行JV表征以确定电池参数，在开路电压、短路电流密度和填充因子分别为1.006 V、3.0507 mA/cm2和0.701时，效率为2.152%。图形抽象
