The authors explore biocarbon as a low-cost, abundant, and environmentally friendly replacement for Pt in dye solar cells. The authors introduce a novel biochar based on brewery residues with good performance and stability potential as a counter electrode in complete dye solar cells, and present the 1st long-term stability test results of a biocarbon in complete dye solar cells. The hydrothermally carbonized and KOH-activated brewer’s spent grain (BSG) offers an extremely high surface area for catalytic reactions (2190 m2/g). Counter electrodes based on this material provide a promising initial performance (efficiency of 3.6 ± 0.2% for biocarbon solar cells compared to 5.3 ± 0.2% for reference cells with Pt catalyst) with current production and the total resistance of solar cells very close to that of Pt based solar cells. In an extended accelerated aging test, the best biocarbon dye solar cell maintained over 86% of its initial efficiency for 3000 h. Also, the biocarbon reduced the degradation via loss of electrolyte charge carriers during aging. Based on these results, the activated BSG biocarbon provides a promising alternative for Pt catalysts. In the experiment, the researchers used many compounds, for example, 1-Methylbenzimidazole (cas: 1632-83-3Product Details of 1632-83-3).
1-Methylbenzimidazole (cas: 1632-83-3) belongs to imidazole derivatives. Imidazole is a heterocyclic compound with a five-membered planar ring. It is amphoteric and highly polar. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Product Details of 1632-83-3
