Abstract:
The present study investigates the usage of a novel natural dye derived from red algae of Morocco in dye-sensitized solar cells (DSSCs) for the first time. The main pigments responsible for sensitizing the semiconductor TiO2 coatings in the red algae were identified as phycoerythrin, carotenoid, and chlorophyll. The efficiency of a DSSC made from red algae was compared to that of a solar cell made from chlorophyll alone. The photovoltaic performance of the DSSC was evaluated through photocurrent density to photovoltage (J-V) characteristic analysis, and the efficiency was found to be 0.93%. To gain insights into its behavior, the absorbance and photoluminescence in a broad range were studied. Both absorbance and photoluminescence exhibited a broad-spectrum range. Additionally, electronic properties, such as HOMO, LUMO, energy gap, and chemical reactivity parameters, were studied using density functional theory (DFT) calculations.
摘要:
本研究首次研究了源自摩洛哥红藻的新型天然染料在染料敏化太阳能电池(DSSC)中的使用。负责敏化红藻中半导体TiO2涂层的主要颜料被鉴定为藻红蛋白,类胡萝卜素,和叶绿素。将由红藻制成的DSSC的效率与仅由叶绿素制成的太阳能电池的效率进行了比较。通过光电流密度-光电压(J-V)特性分析评估了DSSC的光伏性能,效率为0.93%。为了深入了解它的行为,研究了宽范围内的吸光度和光致发光。吸光度和光致发光均表现出宽的光谱范围。此外,电子性质,比如HOMO,LUMO,能隙,和化学反应性参数,使用密度泛函理论(DFT)计算进行了研究。
