ترجمه مقاله Improving the performance of a multi-junction solar cell by optimizing BSF, base and emitter layers Abstract Reducing the recombination rate and increasing the photo-generation rate play a very significant role in improving the performance of the solar cells. In this research, AlGaAs has been used instead of GaAs in emitter layer with reduction in thicknesses of the base in order to decrease the recombination rate and increase the efficiency of the proposed solar cell. In addition, tunnel juncti ...

ترجمه مقاله Simulation Study on the Effects of Changing Band Gap on Solar Cell Parameters Abstract—We perform the numerical analysis of a CIGS solar cell parameters such as open circuit voltage, short circuit current, maximum power, fill factor, and external quantum efficiency as a function of absorber layer band gap. These parameters are known to be the key parameters of a solar cell to determine its performance. We change the band gap of the CIGS absorber layer by changing its ...

ترجمه مقاله Highly efficient ARC less InGaP/GaAs DJ solar cell numerical modeling using optimized InAlGaP BSF layers An effective BSF is a key structural element for an efficient solar cell, either in a multi-junction or in a single-junction device. In this paper, two important materials AlGaAs and InAlGaP with their varied thickness (i.e. 0.05–1.0) μm both for top BSF and bottom BSF cells are investigated using the computational numerical modeling TCAD tool Silvaco ATLAS. It has been found that under t ...
