SISTEMA ROBÓTICO DE BAIXO CUSTO PARA PREPARAÇÃO DE FILMES POR LAYER-BY-LAYER

LOW-COST ROBOTIC SYSTEM FOR PREPARATION OF LAYER-BY-LAYER FILMS. Layer-by-Layer is an efficient technique for the deposition of thin films used in several devices such as sensors, solar cells, and other systems. A robotic system improves process reproducibility, be a stand-alone system, does not demand human participation during process. On hand, commercially available equipment expensive. In this work, we present low-cost built by using materials commonly found that allows performing bathing, drying steps cycles substrates necessary formation LbL films. This technical note presents electronic assembly scheme program developed experiment. The number baths, time deposition, repetitions to result desired film; can easily modified program. prepared experiment were successfully employed preparation compact layers perovskite cells. Therefore, customized needs each research group uses it.
