Abstract The demands of ecofriendly technologies to produce a reliable supply of renewable energy on a large scale remains a challenge. A solar cell based on DSSC (Dye-Sensitized Solar Cell) technology is environmentally friendly and holds the promise of a high efficiency in converting sunlight into electricity. This manuscript describes the development of a light harvester system as a main part of a DSSC. Congo red dye has been functionalized with metals (Fe, Co, Ni), forming a series of complexes that serve as a novel light harvester on the solar cell. Metal-congo red complexes have been characterized by UV-VIS and FTIR spectroscopy, and elemental analyses. The performance of metal complexes in capturing photons from sunlight has been investigated in a solar cell device. The incorporation of metals to congo red successfully improved of the congo red efficiency as follows: Fe(II)-congo red, Co(II)-congo red and Ni(II)-congo red had efficiencies of 8.17%, 6.13% and 2.65%, respectively. This research also discusses the effect of metal ions on the ability of congo red to capture energy from sunlight.

刚果红染料作为太阳能电池上的光收集器的功能化

摘要 需要环保技术来大规模生产可靠的可再生能源供应仍然是一个挑战。基于 DSSC（染料敏化太阳能电池）技术的太阳能电池是环保的，并有望将阳光高效地转化为电能。这份手稿描述了作为 DSSC 主要部分的光收集器系统的开发。刚果红染料已用金属（Fe、Co、Ni）进行功能化，形成一系列络合物，作为太阳能电池上的新型光收集器。金属-刚果红配合物已通过 UV-VIS 和 FTIR 光谱以及元素分析进行​​了表征。已经在太阳能电池装置中研究了金属配合物从阳光中捕获光子的性能。将金属掺入刚果红成功地提高了刚果红的效率如下：Fe(II)-刚果红、Co(II)-刚果红和Ni(II)-刚果红的效率分别为8.17%、6.13%和2.65 ％， 分别。这项研究还讨论了金属离子对刚果红从阳光中捕获能量的能力的影响。
