What is Numerical investigation on efficiency improvement of double layer antireflection coating AZO/buffer/Cu~2~O/CuO on back-surface fluorine-doped tin oxide heterostructure solar cells about?

Optical and electrical features of Cu 2 O solar cells from simple primitive bufferless AZO∕Cu 2 O 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, controlleddefect BSF, and antireflection coating layers under a compatible fabrication process. By considering the interlayer defects, the optimized DLARC∕AZO∕buffer∕Cu 2 O∕CuO on BSF/FTO exhibits an improved efficiency of 9.17%, with a J SC ≈ 11.45 mA∕cm 2 , a V OC ≈ 1.191 V, and a fill factor of 67.22% under simulated illumination (AM 1.5G, 100 mW∕cm 2 ). Finally, the cell underwent simulated moisturized conditions (RH 90% at T 60°C), where its performance dramatically declined with the exposure time. The results show that the models can be adapted for prediction of the Cu 2 O-based-cell behavior prior to fabricating.
