This paper will present recent developments associated with the manufacture of solid state dye-sensitized solar cells (ss-DSCs) at the Sustainable Product Engineering Centre for Innovative Functional Industrial Coatings (SPECIFIC).The approach to translating small lab scale devices to continuous pilot manufactured processes will be presented through the following technology developments (1) Process step evolution for rapid heat treatments to reduce bottlenecks (2) Solution processable blocking layers and (3) Translating architecture; glass based metal evaporated contacts to flexible atmospheric prepared devices.The fabrication process of ss-DSC comprises amongst other processes the deposition of 2 layers of TiO2, a thin compact layer achieved via spray pyrolysis and a mesoporous layer. Here we will demonstrate that the TiO2 layers can be deposited and heat treated in 12s instead of 30mins using Near-IR treatment. Furthermore the TiO2 compact layer can be deposited using a one-step solution processable method instead of via spray pyrolysis.
