摘要：
A theoretical modeling is developed under the theory of Sah Noyce in order to analyze, understand and predict the behavior of heterostructure solar cells. The cell is mainly based on 4 stacked films: glass, ITO, CdS, active layer, and back contact. The presented study is focused on using the optical and electrical analysis to determine which involved parameters are the most critical for efficiency improvement. Considered parameters are depletion region, donor and acceptors' concentrations and effective layer thickness. The ultimate efficiency of the cell is calculated using a Mathematical Modeling System (MMS) developed on Matlab. Using the MMS the quantum efficiency is also obtained and studied. The thickness for the effective layer varies from 0.5 to 2 mu m. For the MMS, three active layers cases were studied: PbS, CdTe, and CdSe. Ultimate efficiency obtained was 10.24, 5.69, and 6.33%, respectively. Standard solar spectra ASTM G-173-03 (International standard ISO-9845-1-1992) was used, under conditions of AM 1.5 direct.
