We report here the manufacturing of a dye-sensitized solar cell (DSSC) by combining roll-to-roll (R2R) liquid flame spray (LFS) deposition of TiO2 nanoparticles with atomic layer deposition (ALD) of TiO2 thin films. Three different LFS deposition times and three different ALD film thicknesses were investigated. The best solar energy conversion efficiency of 1.28 % was achieved from a sample with 100× repeated LFS TiO2 nanoparticle deposition, subsequently coated with a 10 nm ALD TiO2 thin film on top. Our results suggest new routes for fabrication of DSSCs that can be expanded into a complete R2R process allowing a significant reduction of the device unit cost.
