The objective of this research is to determine the optimum condition coating of semi conducting layer in low cost organic solar cells. We have already determined 5 conditions of coating thin films includes type of electron transporting solution, number of electron transporting layer, concentration of electron transporting solution, drop coating volume of electron transporting layer and speed...
A series of sputtered Cox-Cu100-x films with different compositions (x = 88, 76, 65, 52, 38 and 34) were prepared by RF-sputtering process on glass substrate under 10-3 mbar of Ar pressure. XRD results presented both of Co (FCC) and Cu (FCC) phases in (111) plane at 2 = 44.23° and 43.34°, respectively. The intensity of Cu peaks was increased likewise the intensity Co peaks was decreased with...
Granular Co100-xCux films with the different compositions of x = 19, 40, 54, 65 and 76 were prepared on glass substrate by RF-sputtering technique. After deposition, the films were annealed for 30 min at temperature of 400°C in Argon atmosphere. XRD result confirmed that the as-deposited films showed Co (220) and Cu (111) phases and annealed films showed Co3O4 (3 1 1) and CuCoO (3 1 1) phases....
In this work, ZnO transparent conductive thin films doped with 0-5 at% of Gallium (GZO thin films) have been prepared. GZO thin films were deposited by sol–gel dip coating method. Each dip-coated film was baked at 250°C for 5 min and then annealed at 300°C, 400°C, and 500°C for 2 hr under air ambiance. The effects of Ga dopant and annealing temperature on the structure, electrical...
Aluminum-doped zinc oxide (AZO) thin films were fabricated by the pulsed dc magnetron sputtering technique on different types of the substrates. The influences of the argon flow rate on the crystal structures, the physical morphologies, the optical properties, and the electrical attributes were investigated with the grazing-incident X-ray diffraction (GIXRD), the field-emission scanning...
The lifetime of instruments alumina base that operate in an open field environment can be extended via improving their hydrophobicity. One of the solutions of this problem is coated a specific type of layer that can provide hydrophobicity and durable in field environment. Alumina sheets of square shape; 25 x 25 mm, are used as substrate. The alumina surface was activated using plasma...
