Attaining 21.2% performance in a perovskite cell thanks to artificial additive
- South Korean researchers have actually created 2 perovskite solar cells based upon a polymer made with pepper mint oil as well as walnut fragrance preservative, specifically. The brand-new dopant‐free opening transportation polymer is stated to allow longer resilience of the tools as well as to stop lead-leakage.

A research study team from South Korea's Pohang University of Science and also Technology has actually created 2 sorts of perovskite solar battery utilizing pepper mint oil and also walnut scent artificial additive. The cells accomplished performances of 19.9% as well as 21.2%, specifically.
Both cells are based upon a recently made as well as manufactured unique contributor-- acceptor kind polymer that can be liquified in both the pepper mint oil, which is likewise recognized by the name 3-methylcyclohexanone, and also walnut fragrance preservative, which are frequently specified as 2-methyl anisole.
Using these 2 organics solvents is stated to change poisonous chemicals utilized in previous production procedures, the researchers declare.
The brand-new dopant‐free opening transportation polymer, called alkoxy‐PTEG, has the ability to show high solubility also in nonaromatic solvents and also to avoid feasible lead leak using chelation, the research study group mentioned. The chelation is a procedure where bonds in between 2 or even more different binding websites are developed within the exact same ligand team and also a solitary atom. These ligands are the sequestering representatives that can protect against the lead leak from the solar battery.
The study group included both cells likewise revealed even more sturdiness than usual perovskite cells. "They maintained 88% effectiveness after 30 days passed as well as displayed high security," it verified.
Both tools exist in the research Nonaromatic Green‐Solvent‐Processable, Dopant‐Free, as well as Lead‐Capturable Hole Transport Polymers in Perovskite Solar Cells with High Efficiency, released in Advanced Energy Materials.
