In present work, we report synthesis of molybdenum (Mo) thin films by direct current (DC)-magnetron sputtering method. The structural, optical, morphological, and electrical properties were investigated as a function of target-to-substrate distance. From the results, it is evi d ent that with increase in target-to-substrate distance the thickness of films decreases while its sheet resistance an...

The efficiencies of open-air processed Cu2O/Zn(1-x)Mg(x)O heterojunction solar cells are doubled by reducing the effect of the Schottky barrier between Zn(1-x)Mg(x)O and the indium tin oxide (ITO) top contact. By depositing Zn(1-x)Mg(x)O with a long band-tail, charge flows through the Zn(1-x)Mg(x)O/ITO Schottky barrier without rectification by hopping between the sub-bandgap states. High curren...

Phase evolution during the selenization is crucial for high-quality kesterite Cu2ZnSn(S, Se)4 (CZTSSe) absorbers and efficient solar cells. Herein, we regulate kinetic process of phase from Cu+-Sn4+-MOE (MOE: 2-methoxyethanol) system by precisely controlling positive chamber pressure. We found that, at heating-up stage, Se vapor concentration intentionally suppressed in low-temperature region, ...

High-quality absorber films are imperative for highly efficient Cu2ZnSn(S,Se)4 (CZTSSe) thin-film solar cells. Precursor solution chemistry, interconnected with nucleation and the crystal growth process, should be studied insightfully. Thus, creative rationales strategies could proposed to improve quality, carrier characteristics, hence device performance. However, research on precursor chemist...
