Abstract
Optical and electrical features of solar cells from simple primitive bufferless to complex single/double layer-antireflection coating (S/DLARC) on back-surface fluorine-doped tin oxide (BSF/FTO), were numerically studied. The simulated cells were optimized using a low-conduction band offset buffer, controlled-defect BSF, and antireflection coating layers under a compatible fabrication process. By considering the interlayer defects, the optimized on BSF/FTO exhibits an improved efficiency of 9.17%, with a , a , and a fill factor of 67.22% under simulated illumination (AM 1.5G, ). Finally, the cell underwent simulated moisturized conditions ( at ), where its performance dramatically declined with the exposure time. The results show that the models can be adapted for prediction of the -based-cell behavior prior to fabricating.
