• .9.252 Abstract Molybdenum (Mo) is the most commonly used material as back contact in thin-film solar cells. Adhesion of Mo film to soda–lime glass (SLG) substrate is crucial to the performance of solar cells. In this study, an optimized bilayer structure made of a thin layer of Mo on an ultra-thin

• ; bilayer; chromium; DC sputtering; molybdenum; optical reflectance; Introduction Molybdenum (Mo) thin films are widely used as a back contact for photovoltaic devices such as Cu(In1−xGax)S2 (CIGS) and Cu2ZnSnS4 (CZTS) thin-film solar cells. The back contact is the first layer to be deposited and its

• -produced plasma beams. The diameter of the focus spot of laser beam on the target was about 2 mm and could be varied by shifting focal lens. The power density of the laser on the target was 2 × 108 W/cm2 per pulse. Molybdenum (Mo) and silicon (Si) wafers (1 × 1 cm2) as substrates were used and placed 4 cm
