我们以指数级增长的速度贪婪地消耗化石燃料，导致了全球变暖和气候变化。由于这些问题，探索其他清洁能源是至关重要的。本文介绍了柑橘果皮染料敏化太阳能电池（DSSCs）中天然色素的提取及其性能的测定。以天青柑、中华柑、柠檬柑和橘皮为原料提取天然染料，作为光敏剂制备zno基DSSCs。采用紫外-可见吸收、傅里叶变换红外光谱（FTIR）和光致发光光谱技术对天然色素提取物的特征进行了分析。对半导体有源层材料进行了合成和分析。研究了所发明的DSSCs在模拟阳光下的光伏参数特性。叶绿素衍生物在大部分提取的染料中以核心色素和附加色素的形式存在。以黄皮柑橘、中华柑橘、柠檬柑橘和橘皮柑橘为原料，叶绿素a染料ZnO太阳能电池的光能转换效率分别为0.028%、0.013%、0.004%和0.022%。与其他提取物相比，天竺葵提取物具有更好的光敏性能，这可能是由于天竺葵色素与zno光活性层表面之间的电荷转移更好。利用天然色素和ZnO光活性层基DSSCs实现了可见光到电的转换，从而获得了优异的光电特性。
Our voracious consumption of fossil fuels at an exponentially increasing rate has led to global warming and climate change. As a result of these problems, it is crucial to exploreother sources of clean energy. The natural pigmentsextraction and the performancedetermination in Dye-Sensitized Solar Cells (DSSCs)from fruit peels of citrus were presented in this paper. Extraction of natural dye of citrus fruit peels of Citrus paradisi, Citrus sinensis, Citrus limonumandCitrus tangelo were employed as light sensitizers in fabricating ZnO-based DSSCs. The natural pigments extracts characteristics were analyzedby UV-Vis absorption, Fourier transforms infra-red (FTIR) and Photoluminescence spectroscopy techniques. The semiconductor active layer material was synthesized and analyzed. The characteristics of photo-voltaic parameters for the invented DSSCs were studied under simulated sunlight. The presence of chlorophyll derivative in most of the extracted dyes is evident as the core pigments with additional accessory pigments. The conversion efficiencies of sunlight to electrical energy of pheophytin ‘a’ dye ZnO based solar cells are calculated to be 0.028%, 0.013%, 0.004% and 0.022% for Citrus paradisi, Citrus sinensis, Citrus limonumand Citrus tangelo, respectively. Better performance of photo-sensitized was observed for the extracts of Citrus paradisicompared to the other extracts and this may be owing to the better charge transfer between the pigments of Citrus paradisi and surface of ZnOphotoactive layer. The conversion of visible light to electricitywas produced from natural pigments and ZnO photoactive layerbased DSSCs, resulted into superb photo-electric characteristics.
