Developing an efficient material as a counter electrode (CE) with excellent catalytic activity, intrinsic stability, and low cost is essential for the commercial application of dye-sensitized solar cells (DSSCs). Transition metal phosphides have been demonstrated outstanding multifunctional catalysts in broad range energy conversion technologies. Here, we exploited different phases iron phosphi...

Vibrational energy harvesters, which can convert mechanical distributed widely in the surrounding environment to electrical a convenient, eco-friendly and sustainable way, have attracted great attention both academia industry. In this study, resilient electret film-based vibrational harvester with V-shaped counter electrode is introduced, simulated constructed. A negatively charged fluorinated ...

We explore biocarbon as a low-cost, abundant, and environmentally friendly replacement for Pt in dye solar cells. introduce novel biochar based on brewery residues with good performance stability potential counter electrode complete cells, present the first long-term test results of The hydrothermally carbonized KOH-activated brewer's spent grain (BSG) offers an extremely high surface area cata...

In this study, we develop the optimum composition of copper oxide/ruthenium oxide and multi-walled carbon nanotubes (CuO/RuO2/MWCNTs) ternary nanocomposite via a hydrothermal method as an efficient electrode material for supercapacitor applications. The ratio between CuO RuO2 varied to improve electrochemical performance electrode. synthesized nanocomposites are analyzed by high-resolution scan...
