“…Transparent conducting oxides (TCOs) have been widely used for various kinds of optical and electrical devices due to their excellent combined electrical conductivity and optical transparency in the visible range of the electromagnetic spectrum [1]. Currently, the different types of TCO structures such as TCO/Metal/TCO and TCO/TCO have been proposed to enhance the TCO properties towards solar photovoltaic (PV) applications [2,3]. The dominant TCO is indium tin oxide (ITO) as it shows moderate electrical resistivity and good transmittance in the visible range [4].…”

“…Spray coating does not seem to be the right method for the fabrication of the Si layers, however, it has been employed to synthesize their electrodes, such as ZnO:In layers [59], transparent conductive F-doped SnO 2 [60], In-doped ZnO [61], Al-doped ZnO and F-doped SnO 2 [62] thin films.…”

Abstract:The capability to fabricate photovoltaic (PV) solar cells on a large scale and at a competitive price is a milestone waiting to be achieved. Currently, such a fabrication method is lacking because the effective methods are either difficult to scale up or expensive due to the necessity for fabrication in a vacuum environment. Nevertheless, for a class of thin film solar cells, in which the solar cell materials can be processed in a solution, up scalable and vacuum-free fabrication techniques can be envisioned. In this context, all or some layers of polymer, dye-sensitized, quantum dot, and copper indium gallium selenide thin film solar cells illustrate some examples that may be processed in solution. The solution-processed materials may be transferred to the substrate by atomizing the solution and carrying the spray droplets to the substrate, a process that will form a thin film after evaporation of the solvent. Spray coating is performed at atmospheric pressure using low cost equipment with a roll-to-roll process capability, making it an attractive fabrication technique, provided that fairly uniform layers with high charge carrier separation and transport capability can be made. In this paper, the feasibility, the recent advances and challenges of fabricating spray-on thin film solar cells, the dynamics of spray and droplet impaction on the substrate, the photo-induced electron transfer in spray-on solar cells, the challenges on characterization and simulation, and the commercialization status of spray-on solar cells are discussed.

“…Such the sandwiched structure provides the immunity to metal diffusion and a low-defect AZO/a-Si:H interface, where the AZO acted as a protective layer eliminating H þ ion bombardment on the electrode substrate. 14 The low plasma power density for the a-Si:H deposition can also minimize the ion bombardment on the substrate. 15 Moreover, the nano-scale smooth surface of the TCO electrode by smoothening the protrusion and sharp valley of FTO/Au-NPs is beneficial to the growth of the dense a-Si:H film of low-defect density.…”

A sandwiched light-trapping electrode structure, which consists of a capping aluminum-doped ZnO (AZO) layer, dispersed plasmonic Au-nanoparticles (Au-NPs), and a micro-structured transparent conductive substrate, is employed to stabilize and boost the conversion-efficiency of hydrogenated amorphous silicon (a-Si:H) solar cells. The conformal AZO ultrathin layer (5 nm) smoothened the Au-NP-dispersed electrode surface, thereby reducing defects across the AZO/a-Si:H interface and resulting in a high resistance to photo-degradation in the ultraviolet-blue photoresponse band. With the plasmonic light-trapping structure, the cell has a high conversion-efficiency of 10.1% and the photo-degradation is as small as 7%.
