  • Abstract:

The study examined the electronic properties and solar device applications of Bi and Sb contacts to Si thin films at temperatures 303-353K. The samples of thickness 1000 Å were vacuum deposited at a pressure of 5x10-5torr with the constituent elements of 99.99% purity, Ventron Germany. The analysis of the samples showed that the conductivity increases with temperature while the activation energies had values of 0.033 eV, 0.124 eV for the Bi/Si and Sb/Si samples respectively. These properties in addition to the electrical characterization of the samples were observed to compare favourably with that of semiconductor properties widely adapted for use in solar devices and opto electronic applications. Hence, the samples in the study have good potentials for use in the fabrication of solar devices and light amplification systems.
