Numerical Simulation of CdS/CIGS Tandem Multi-Junction Solar Cells with AMPS-1D

Numerical modeling of polycrystalline thin-film solar cell serves as an imperative procedure to test the suitability of proposed physical clarification and to anticipate the effect of physical changes on cell performance. All in all, this must be conducted with only partial knowledge of input parameters. In this paper, we evaluated the numerical simulation of CdS/CIGS tandem multi junction sola...

The Effect of Change the Thickness on CdS/CdTe Tandem Multi-Junction Solar Cells Efficiency

 Researchers in the field of simulation have been mainly interested in the question of how to increase the efficiency of solar cells. Therefore this study aimed to investigate CdS/CdTe solar cells by applying AMPS-1D software. The impact of semiconductor layers thickness on the output parameters of the CdS/CdTe solar cell is being analyzed and studied carefully, for example, fill factor, effici...

Quantum junction solar cells.

Colloidal quantum dot solids combine convenient solution-processing with quantum size effect tuning, offering avenues to high-efficiency multijunction cells based on a single materials synthesis and processing platform. The highest-performing colloidal quantum dot rectifying devices reported to date have relied on a junction between a quantum-tuned absorber and a bulk material (e.g., TiO(2)); h...

Performance evaluation of multi-junction solar cells by spatially resolved electroluminescence microscopy

An electroluminescence microscopy combined with a spectroscopy was developed to visually analyze multi-junction solar cells. Triple-junction solar cells with different conversion efficiencies were characterized by using this system. The results showed that the mechanical damages and material defects in solar cells can be clearly distinguished, indicating a high-resolution imaging. The external ...
