“…Blade coating has the advantage of exhibiting largearea uniformity, small amount of material waste, preventing of interlayer dissolution, compatibility to a roll-to-roll fabrication, as well as a more economical use of active material while still giving the possibility to prepare welldefined films [6,17,42]. A rapid drying process in the blade coating method will prevent fabrication throughput from being slowed by the conventional solvent annealing process [42].…”

“…A rapid drying process in the blade coating method will prevent fabrication throughput from being slowed by the conventional solvent annealing process [42]. In this method, the film thickness can be controlled by adjusting the fabrication parameters such as the solution concentration, the blade gap and the blade coating speed [6].…”

“…2 illustrates the schematic diagram of the blade coating method. Tsai et al [42] demonstrated a high performance of PSC based on PBDTTT-C-T:PCBM with the chlorine-free solvents toluene and xylene using blade coating methods. The main reason for the improvement in PSC performance is the good solubility of PBDTTTC-T in the chlorine-free solvents.…”

“…Before coating the active layer, about 3 wt% 1,8-diiodooctane (DIO) was added in the solution as an additive which could improve photovoltaic results. [13][14][15] The mixed solution was heated at 80 • C then blade coated using 15 µl of solution with the hotplate at 80 • C. After blade coating the organic solution, the hot wind was applied immediately for 6 s to dry the film. The PBDTTT-C-T:[70]PCBM layer was annealed at 120 • C for 20 minutes.…”

The inverted organic solar cell was fabricated by using sol-gel indium-gallium-zinc-oxide (IGZO) as the electron-transport layer. The IGZO precursor solution was deposited by blade coating with simultaneous substrate heating at 120 °C from the bottom and hot wind from above. Uniform IGZO film of around 30 nm was formed after annealing at 400 °C. Using the blend of low band-gap polymer poly[(4,8-bis-(2-ethylhexyloxy)-benzo(1,2-b:4,5-b’)dithiophene)-2,6-diyl-alt- (4-(2-ethylhexanoyl)-thieno [3,4-b]thiophene-)-2-6-diyl)] (PBDTTT-C-T) and [6,6]-Phenyl C71 butyric acid methyl ester ([70]PCBM) as the active layer for the inverted organic solar cell, an efficiency of 6.2% was achieved with a blade speed of 180 mm/s for the IGZO. The efficiency of the inverted organic solar cells was found to depend on the coating speed of the IGZO films, which was attributed to the change in the concentration of surface OH groups. Compared to organic solar cells of conventional structure using PBDTTT-C-T: [70]PCBM as active layer, the inverted organic solar cells showed significant improvement in thermal stability. In addition, the chemical composition, as well as the work function of the IGZO film at the surface and inside can be tuned by the blade speed, which may find applications in other areas like thin-film transistors.
