The structural evolution and electrochemical properties of the textured Cu2O thin films

Inorganic Solar Cells Based on Electrospun ZnO Nanofibrous Networks and Electrodeposited Cu2O

“…The films are polycrystalline and have cubic structure (JCPDS 05-0667). The films prefer the (200)-texture at low pH values (e.g., pH = 8) and (111)-texture at high pH values (e.g., pH = 9–13), agreeing with earlier results [ 11 , 22 , 37 , 38 ]. It is noted that the (002)-oriented ZnO-NFs favor better matching with the (111)-texture Cu 2 O film [ 39 ].…”

“…These results confirm the fact that the growth time of ~30 min is the optimized one for the cells. Compared with the other cells, the better performance can be attributed to the effective charge transfer between the ZnO nanofibrous networks and Cu 2 O films and the higher absorption [ 37 ]. Figure 13d shows the equivalent circuit, where R s is included due to contacts and wire.…”

Electrochemical flow-based solution–solid growth of the Cu2O nanorod array: potential application to lithium ion batteries

“…24 It was previously reported that four-faced pyramid Cu 2 O films had the [100]-preferred orientation because the (111) plane, with its lowest surface energy, is the most stable and that the growth direction of the Cu 2 O film was kinetically controllable by the deposition parameters such as deposition current, reduction potential and pH of electrolyte. [25][26][27] Thus, it is presumed that the triangular growth of [111]-longitudinal Cu 2 O might be related to the nonequilibrium kinetics caused by the high reduction potential. The one-dimensional growth of Cu 2 O nanorods was closely related to the electric field enhancement on the sharp tips (Fig.…”

The effect of additives on the Cu2O crystal morphology in acetate bath by electrodeposition

“…The development of micro-or nanomaterials with special size and well-defined shape may open new opportunities for exploring material physical and chemical properties because their electronic structure, bonding, surface energy, and chemical reactivities are directly related to their surface morphology [10,11]. Various methods have been developed for synthesizing different Cu 2 O micro-and nanostructures, such as gasphase deposition techniques [12,13], electrodeposition [14][15][16][17][18][19][20][21][22] and various solution methods [23][24][25][26][27][28]. Among these techniques, electrochemical deposition has shown a powerful ability to control the crystallization engineering of Cu 2 O, and it presents a simple, quick, and economical method for the preparation of large area films, and has the advantage of allowing the controlled and patterned growth of structures.…”
