Cu2O is a model p-type semiconductor for photocathodes in photoelectrochemical (PEC) water splitting cells. However, major challenges remain in controlling its deposition into thin and homogeneous semitransparent films. Herein, we report a new route to construct thin homogeneous Cu2O … Characterization of Cu2O nanoparticles. X-ray diffraction (XRD) studies were carried out for the purpose of phase identification, crystallite size, and lattice strain of the powder sample of cuprous oxide (Cu 2 O) nanoparticle. Subsequently, the XRD patterns were analyzed with the help of JCPDS (Joint Committee on the Powder Diffraction Toshiba Corporation today announced that it has successfully raised the power conversion efficiency (PCE) of its transparent Cu2O solar cell to 8.4 percent, the world's highest level for a reported Cu2O solar cell. With the cell positioned as the top cell over a 25 percent PCE silicon cell (Cu2O …
Transparency and Morphology Control of Cu2O Photocathodes
In this work, we demonstrate the systematic and delicate geometry control of Cu2O nanocrystals by taking advantage of the selective surface stabilization effect. A variety of Cu2O … Cuprous oxide Cu2O is a semiconductor, and it has a cubic structure having a band gap of 2.17ev. Cupric oxide CuO is a p-type semiconductor having monoclinic crystal … Equivalent weight can be calculated using the formula. Equivalent weight = Atomic weight/Valency. Equivalent weight of copper = Molecular weight of copper/ Valency of copper. Molecular weight of copper is 63.55 g. The Valency of copper in Cu 2 O … Copper (I) oxide. Molecular Formula Cu. 2. O.
