In materials science laboratories, this compound is used to form a molecular layer just one molecule thick on the surface of transparent conductive oxides, which then functions as the hole-transporting layer in inverted-structure perovskite solar cells. This monolayer approach replaces conventional hole-transporting layers that are far thicker and consume considerably more material per device.\u003c\/p\u003e\n\u003cp\u003eThe property that makes this material attractive is the ability of the phosphonic acid group to bind strongly and spontaneously to metal oxide surfaces such as indium tin oxide, forming an ordered layer through nothing more than immersion or spin coating from an alcohol solution. The bromine substituent on the carbazole ring shifts the energy levels and the surface dipole moment, so that energy band alignment with the perovskite layer can be tuned — something that translates directly into the open-circuit voltage of the finished device. Because the layer is only one molecule thick, the series resistance it introduces is very small and parasitic light absorption is negligible.\u003c\/p\u003e\n\u003cp\u003eIn Indonesian laboratories, Br-2PACz is typically handled within university and national research group programmes working on perovskite photovoltaics, where it is dissolved in alcohol solvents and applied to patterned oxide substrates under controlled conditions. It generally sits alongside other perovskite precursors and charge transport materials on the same project bench, and is used in small quantities per experiment, which makes careful stock handling and consistent solution preparation an important part of the workflow.\u003c\/p\u003e\n\u003ch3\u003eLaboratory Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInverted perovskite solar cell fabrication — the phosphonic acid anchor forms the hole-transporting monolayer directly on transparent conductive oxide, replacing much thicker conventional hole transport layers.\u003c\/li\u003e\n\u003cli\u003eEnergy level alignment studies — the bromine substituent on the carbazole ring shifts energy levels and surface dipole, allowing researchers to tune band alignment against different perovskite compositions.\u003c\/li\u003e\n\u003cli\u003eOpen-circuit voltage optimisation — because band alignment with the perovskite layer is adjustable through this substituent, the material supports systematic device voltage improvement experiments.\u003c\/li\u003e\n\u003cli\u003eSurface modification of metal oxide electrodes — spontaneous and strong binding to surfaces such as indium tin oxide allows ordered layer formation by simple immersion or spin coating.\u003c\/li\u003e\n\u003cli\u003eLow-loss charge extraction layer research — the single-molecule thickness keeps series resistance very small and parasitic light absorption negligible, useful for loss-analysis studies.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: TCI\u003c\/li\u003e\n\u003cli\u003eProduct code: B6391\u003c\/li\u003e\n\u003cli\u003eCAS number: 2762888-11-7\u003c\/li\u003e\n\u003cli\u003eCategory: Materials Science \u0026gt; Electronic Materials \u0026gt; Perovskite Solar Cell (PSC) Materials\u003c\/li\u003e\n\u003cli\u003ePack sizes: available in research-scale packaging; please refer to the current catalogue listing for available sizes\u003c\/li\u003e\n\u003cli\u003eStorage: store according to the manufacturer's stated conditions on the product label\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHandling and Storage\u003c\/h3\u003e\n\u003cp\u003eStore the material in its original tightly closed container, kept in a cool, dry and well-ventilated area away from direct sunlight, moisture and incompatible substances, and follow the storage conditions stated by the manufacturer on the product label. Since this compound is used to prepare alcohol-based solutions for thin-film deposition, containers should be resealed promptly after weighing to limit moisture uptake and contamination that could affect monolayer quality. Handle in a fume hood using appropriate personal protective equipment including safety glasses, gloves and a laboratory coat. Consult the manufacturer's Safety Data Sheet before use, and dispose of residues and contaminated materials in accordance with applicable laboratory chemical waste procedures.\u003c\/p\u003e","brand":"TCI","offers":[{"title":"500mg","offer_id":48085937651930,"sku":"TCI2510B639113271","price":6042750.0,"currency_code":"IDR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/7156\/8602\/files\/TCI2510B6391.jpg?v=1771058439","url":"https:\/\/amiscientific.com\/en\/products\/tci2510b639113271","provider":"AMI Scientific","version":"1.0","type":"link"}
