Silicon heterojunction (SHJ) solar cell has attracted increasing attention for the excellent passivation [[5] ... Compare to full area seed layer deposition, efforts have been paid to directly plating on TCO film. A nickel seed layer (typical 1–3 μm thickness) with good mechanical adhesion has been used for electroplated contact [27].
The Ni–Fe layered double hydroxides allow the capacity per nickel atom to be multiplied by 1.8 in comparison to the conventional β-Ni (OH) 2 material which suggests that the nickel …
The interfacial coupling between cube-shaped nickel tin oxide (NSO) and gCN is achieved through the surface sites in NSO. An improved hydrogen production rate of 646 µmol g −1 h −1 is measured in the composite (NSO-gCN), which is twice that in gCN, using triethanolamine (TEOA) and chloroplatinic acid (1% w/w) as holes scavenger and …

In comparison to Zn batteries, iron-based batteries exhibit remarkable promise to further reduce the cost [18], [19], [20]. Iron is the second abundant metal element in the earth''s crust and is ~560 times more than …
The application of nickel chloride (NiCl 2) in thermal battery has been restrained for its poor electronical conductivity, which causes the voltage delay at the initial discharging process. In this …
Ni x Co y-BDC precursors were supported on nickel foam by reacting H 2 BDC with different Ni 2+ / Co 2+ ratios via a facile solvothermal treatment at 100 C for 12 h. After the phosphorization reaction, Ni x Co y P-BDC …

In the past few years, it was discovered that Ni(OH) 2 is an effective photocatalyst for CO 2 as a chemical fuel catalyst. Ni(OH) 2 nanosheets were prepared by simple wet treatment and electric transformation of nickel-containing wastewater. The Ni(OH) 2 /Ce(OH) 4 hybrid nanosheets were prepared by Ce doping experiment, and …
