Ossila Aluminum Zinc Oxide Powder (M2486A1) is a pale yellow, high-purity (99.9%) powder of aluminum-doped zinc oxide, commonly abbreviated AZO (CAS 952185-00-1). It belongs to the family of transparent conducting oxides and is chosen for transparent conductive layers in solar cells, OLEDs and displays, as well as for electrodes, anti-static coatings and sensors. The particle size is ca. 30 nm.
Because AZO transmits visible light well while conducting electricity, it serves as an alternative to indium tin oxide (ITO). Its constituent elements are relatively abundant, which supports the development of lower-cost devices.
The work function of AZO lies between 4.92 and 5.13 eV, depending on the aluminum doping level. In a simple Au/spiro-OMeTAD/Perovskite/AZO/glass perovskite solar cell, AZO used as the electron collecting layer gave a Voc of 0.94 V, Jsc of 20.2 mA/cm2, fill factor of 0.67 and PCE of 12.6%. AZO also helps suppress interfacial recombination, with a reported PCE of 27.2% in a lead-free ITO/ZnO/AZO/Cs2BiAgI6/V2O5/Au perovskite device. Available in 50 g and 100 g packs.
