“…Spraying at various substrate temperatures between 180°C to 290°C does not affect the crystalline structure but an increase in the layer growth rate is observed with rising temperature (not shown here). No other crystalline phases of In x S y , In x O y or In x Cl y are detected in any of the measured films, as also reported earlier [12].…”

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.

“…Various methods are under investigation to find an optimum deposition process for this compound -e.g. ALD (Atomic Layer Deposition), thermal evaporation, sputtering, and ultrasonic spray pyrolysis [1][2][3][4][5]. So far the ALD technique is the only indium sulphide deposition method which demonstrated high efficiencies on module areas up to 30×30 cm 2 (max.…”
