{"product_id":"cmpecsctc","title":"Mini Photoelectrochemical (PEC) Single-Chamber Test Cell (10 mL), CMPECSCTC","description":"\u003cp\u003eA mini photoelectrochemical (PEC) test cell is a compact, high-precision reactor designed to evaluate the solar-to-chemical conversion efficiency of semiconductor films while using minimal amounts of electrolyte and catalyst material. In research areas like CO2 reduction (CO2RR) or solar water splitting, the \"mini\" form factor (typically 5–25 mL) is strategically used to concentrate reaction products, making them easier to quantify via Gas Chromatography (GC) or HPLC. This setup is the primary tool for measuring Photocurrent Density, Mott-Schottky plots, and Photostability of thin-film semiconductors like TiO2, WO3, or BiVO4 deposited on FTO\/ITO glass.\u003c\/p\u003e\n\u003cp\u003eThe cell is designed to place the photo-working electrode as close to the optical window as possible while maintaining a standard three-electrode electrochemical environment. (1) \u003cstrong\u003eOptical Window\u003c\/strong\u003e: A flat Quartz (Fused Silica) window is essential. It ensures high transmission (\u0026gt;90%) of UV light, which is necessary for wide-bandgap semiconductors, and eliminates the \"lensing effect\" found in curved glass cells. (2) \u003cstrong\u003eSingle-Chamber Geometry\u003c\/strong\u003e: Unlike an H-cell, all three electrodes share the same electrolyte volume. This is ideal for fundamental studies where product crossover is not a primary concern (e.g., initial catalyst screening). (3) \u003cstrong\u003e\"Thin-Gap\" Concept\u003c\/strong\u003e: These cells often feature an adjustable internal volume, allowing the electrode to sit within 1–5 mm of the quartz window. This minimizes \"solution shielding,\" where the electrolyte absorbs or scatters photons before they reach the catalyst.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eCMPECSCTC (C-MPECSCTC)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCell Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eThe PEC cell body is made of PTFE, which is highly resistant to harsh electrochemical environments. \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe side-illumination window is made of quartz with light transparence \u0026gt;95%. \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe working electrode sheet is pressed and tighten by back-support. \u003c\/li\u003e\n\u003cli\u003eThe counter and reference electrode is Pt wire and Ag\/AgCl, respectively, which have been installed in the cell. \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe light illumination area is 1 cm2 (customized areas can be customized upon request). \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCell volume: 10 mL\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003eThe cell components should be thoroughly cleaned and dried after use. \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"GSRL","offers":[{"title":"Default Title","offer_id":47454316331238,"sku":"CMPECSCTC","price":999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CMPECSCTC_main.png?v=1773560465","url":"https:\/\/echemsupplies.com\/products\/cmpecsctc","provider":"EChem Supplies","version":"1.0","type":"link"}
