摘要

CdS/CdTe are still advance structures for solar cells. The performance and efficiency of such devices strongly depend on structure, thickness, size of crystallites and layer morphology. In this paper we have applied pulsed laser deposition (PLD) method for CdTe and CdS layers as well as CdS/CdTe heterostructures fabrication. The layers were deposited from single crystal targets onto ITO/glass substrates. PLD of CdTe layers results in polycrystalline mode of growth consisting of regular isolated crystallites of 0.5 μm size almost the same for all of them. Such crystal structure of layers seems to be very promising for solar cells design. The crystal structure of layers was examined by SEM as well as by RHEED. The characterization of layers and CdS/CdTe junctions was completed by optical and Ⅰ- Ⅴ measurements.
