Copper and nickel co-doping effects on the structural, optical and electrical properties of tungsten trioxide nanoparticles prepared by co-precipitation technique Article

Lachore, Wegene Lema; Hone, Fekadu Gashaw; Andoshe, Dinsefa Mensur; Tegegne, Newayemedhin A; Mekonnen, Mulualem Abebe (2022-03-31)

The pristine WO3 (tungsten trioxide) and Cu/Ni Co-doped WO3 nanoparticles were synthesized by the co-precipitation synthesis methods with fixed wt.% of nickel, i.e., 5 wt.%, and different wt.% of copper, i.e., 2, 3, 5 ...
Recent progress in electron transport bilayer for efficient and low‑cost perovskite solar cells: a review Article

Lachore, Wegene Lema; Andoshe, Dinsefa Mensur; Mekonnen, Mulualem Abebe; Hone, Fekadu Gashaw (2021-10-05)

Today, organic–inorganic perovskite hybrid solar cells are especially attracted by the energy industries to design and develop new-generation photovoltaic devices. They are the most promising materials for high PCE and ...
Structural, optical and electrical properties of copper (Cu) and [nickel (Ni), copper]: co‑doped SnO2 nanoparticles prepared by sol–gel method Article

Lachore, Wegene Lema; Andoshe, Dinsefa Mensur; Hone, Fekadu Gashaw; Mekonnen, Mulualem Abebe (2022-05-21)

In this work, the un-doped, Cu-doped, and (Ni, Cu) co-doped SnO2 nanoparticles (NPs) were synthesized using the sol–gel method with a fxed concentration of copper dopant while varying the nickel concentrations. The ...
