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.

“…The first approach is unsuitable for solar cell device fabrication because the 'as-synthesized' nanoparticles are non-compact and highly dispersed with larger grain boundaries. Hence, there is greater tendency of charge trapping at the grain boundaries which eventually reduces the PCE [26]. In the second approach, the synthesized nanoparticles are annealed in sulfur or selenium atmosphere which is referred to as sulfurization or selenization.…”

“…A few leading thin film solar cell companies such as Nanosolar Pte Ltd. have industrially and massively manufactured CIGS thin film solar cells by utilizing an 'industrial' printing process to coat CIGS nanoparticle inks on flexible and light weight substrates for costefficient solar cell products. Although the screen printing method is successful in coating the above mentioned solar cell materials, only quite recently a few reports appeared to report screen printed CZTS films [12][13][14][15]. In those reports, CZTS solar cell has been fabricated by printing CZTS powders, and printing is proved to be a cheap and effective method.…”
