Numerical Analysis on Design of High Performance CSTZ Solar Cells

The surging of photovoltaics has witnessed the boost of numerous fascinating approaches to the enhancement of power conversion efficiencies (PCE) of the devices. For the search of new metal-halide CZTS solar cell materials, tolerance factors are calculated from the ionic radius of each site and are often utilized as the critical factors to expect the materials forming CZTS structure. Significant progress in photovoltaic conversion of solar energy can be achieved by new technological approaches that will improve the efficiency of solar cells and make them appropriate for mass production. The paper presents the numerical analysis on design of high performance CSTZ solar cells with the help of MATLAB programming. The performance reliance on physical properties is estimated, together with the layer thickness, carrier density, defect density and interface defect density. The best possible the layer thickness and carrier density were originated in this study. The defect density in the absorber would be controlled for reducing the recombination. The interface between the layer of absorber and the layer of buffer is essential for the performance of that solar cell. The interface defect density is embarrassed to accomplish enviable conversion efficiency. The results confirm that the experimental works could be met with the theoretical analysis in this paper.
