摘要: We report on the fabrication of efficient polymer solar cells via airbrush coating as a promising method for low cost and large area production. used dual action deposition active layer from poly(3-hexylthiophene):[6,6]-Phenyl C61 butyric acid methyl-ester (P3HT:PCBM) blend dissolved in co-solvent mixture. The resulting devices were measured under AM1.5G conditions compared with spin-coated ones air nitrogen atmosphere. High power conversion efficiencies (η=4.1%) obtained by optimizing parameters spray system (i.e. film thickness, time spray, distance between sample airbrush, substrate temperature, etc.). measurements also showed good repeatability uniformity despite relatively rougher surface.
