Optical and electrical parameters of biphasic silicon with different crystalline volume fraction (fc) were estimated via effective medium approximation method and experimental results. Then software AMPS-1D has been performed to investigate the influence of fc on biphasic silicon as the intrinsic layer on the performance of biphasic silicon single-junction and amorphous silicon/biphasic silicon double-junction...
We synthesized undoped and Mn-doped ZnO films on glass substrates using the sol-gel technique. The micro-structure, morphology and optical properties of ZnO films were studied by using X-ray diffraction, Atomic Force Microscope and UV-visible transmission spectra. After annealed at a temperature lower than 550°C by Rapid Thermal Processing (RTP), all the ZnO films are polycrystalline with a hexagonal...
The intrinsic hydrogenated nano-crystalline silicon (nc-Si:H) films for p-i-n tandem solar cells have been deposited by plasma enhanced chemical vapor deposition (PECVD) assisted with direct current bias, and were investigated by four-point probe sheet resistance measurement, Raman and ultraviolet-visible (UV-VIS) transmission spectra. By varying technological conditions, the dependence of the conductivity...
The intrinsic hydrogenated nano-crystalline silicon (nc-Si:H) films for p-i-n tandem solar cells have been deposited on the corning 7059 glass substrates by plasma enhanced chemical vapor deposition (PECVD) assisted with direct current bias, and were characterized by Raman and ultraviolet-visible (UV-VIS) transmission spectra. By working on varying hydrogen dilution of Silane (??) and direct current...
