| Abstract | ||
| CdS/CdTe heterojunction has been fabricated by thermal evaporation technique. Polycrystalline CdTe and CdS films have been prepared by thermal evaporation technique on glass substrate with heating substrate of 423 K of 1 and 0.1 m thicknesses respectively. The heterojunction annealed at 573 K. The current – voltage under illumination showed that the photocurrent increased with increasing the incident illumination intensity for CdS/CdTe heterojunction, and no photovoltaic effect was observed. The CdS/CdTe heterojunction has been heat treated after evaporated CdCl2 film at 573 K under vacuum for 30 min., the heterojunction has better photovoltaic properties. The open circuit voltage (Voc) and the short circuit current (Isc) increased with increasing the incident illumination intensities, and the efficiency is 1.24 % at 78 mW/cm2. | ||
