![]() ![]() It is one of two well characterized cobalt oxides. of Coo, 24 : 46143 ( C00-161614 ) properties for use as cobalt - 60 heat. Cobalt(II,III) oxide is an inorganic compound with the formula Co3O4. The reproducibility and enduring stability of those devices were examined to show the outstanding long-term stability of the devices made of metal oxide HEL, for which the CoO x device retained PCE ≈ 12% for over 1000 h.Ĭobalt oxide hole-extraction layer perovskite solar cell photoluminescence photovoltaic devices. COBALT OXIDES SUBJECTS 288 1206-1 ) compatibility with rhenium at 1500 C. Photoluminescence (PL) spectra and the corresponding PL decays for perovskite deposited on varied HEL films were recorded to obtain the hole-extracting characteristics, for which the hole-extracting times show the order CoO x (2.8 ns) < PEDOT:PSS (17.5 ns) < NiO x (22.8 ns) < CuO x (208.5 ns), consistent with the trend of their photovoltaic performances. We characterized the chemical compositions with XPS, crystal structures with XRD, and film morphology with SEM/AFM techniques. The magnetic measurement showed that the prepared nanocomposite displays room. In this review paper, various methods for formation of thin films were. The devices fabricated according to a simple solution procedure showed the best photovoltaic performance attaining power conversion efficiency (PCE) of 14.5% under AM 1.5 G 1 sun irradiation, which is significantly superior to those of materials fabricated with a traditional HEL such as PEDOT:PSS (12.2%), NiO x (10.2%), and CuO x (9.4%) under the same experimental conditions. The cobalt oxide particles in their nature were polycrystalline, and the crystallite sizes varied from 10 to 20 nm. Cobalt oxides are semiconductors and this material is very useful in electronic, optical and catalytic applications. ![]() CoO x is a promising hole-extracting layer (HEL) for inverted planar perovskite solar cells with device configuration ITO/CoO x/CH 3NH 3PbI 3/PCBM/Ag. ![]()
