Different Thickness

nanoAg island thin films with different thickness have been prepared by vacuum vapor deposition method on ITO substrates for organic solar cells. UV-Vis absorption spectrum and surface morphology have been studied by UV-Vis scanning spectrophotometer and SEM. The influence of different thickness nanoAg has also been discussed. The results show that, when the nanoAg thickness is 3.0 nm, the surface plasmon response is most obvious, the resonance absorption peak appears red-shift, the surface plasmon response could enhance optical absorption, photocurrent, fill factor and power conversion efficiency obviously. The research results provide theoretical guidance to optimize the design and increase the performance of solar cells.

Layer Deposition

The perovskite solar cells (PSCs) with Al2O3 passivation layer were fabricated and characterized. The PSC have some advantages of easier and cheaper fabrication process than that of conventional Si solar cells, III-V compound semiconductor solar cells, and organic solar cells. The perovskite light harvester, CH3NH3PbI3, was deposited by vapor deposition on [compact TiO2 / F-doped tin oxide (FTO) / glass]. The advantage of vapor deposition over solution process is expected to be able to offer the thin film with smoother surface over larger area. Then, Al2O3 passivation layer was deposited by atomic layer deposition (ALD) on the CH3NH3PbI3 light harvester. Al2O3 passivation layer was expected to prevent the CH3NH3PbI3 light harvester from oxidation and improve the solar cell efficiency, and ALD has been one of the most effective methods to deposit Al2O3 thin film for last 25 years. The atomic layer deposited Al2O3 layer thickness was optimized from the solar cell characterization. The optimized power conversion efficiency (PCE) and Al2O3 thickness were ~8.0 % and ~10.0 nm, respectively.
