Description
Organic-inorganic hybrid perovskites are currently some of the most promising photovoltaic materials to produce highly efficient and cost-effective solar cells. Currently, many approaches have been proposed to prepare high-quality perovskite layers. The antisolvent technique is an effective and widely used method that can be done by dropping antisolvent into the rotating precursor surface during the spin-coating process. This technique is used to rapidly decrease the precursor's solubility, leading to a crystal-like uniform and dense perovskite layer. In the development of perovskite solar cells, three main areas are being developed: efficiency, stability, and reproducibility. This work concentrates on improving a reproducible and large scale (>1 cm^2) perovskite solar cells by using an automatic liquid injection machine in the antisolvent method. Moreover, the properties of the perovskite solar cells were compared with the devices prepared by manual liquid dropping. Liquid drops with the automatic liquid injection machine are more accurate and consistent. The characteristics can reduce tolerances from manual production. Our work increases the reproducibility and the precision for the development of large-scale perovskite solar cells. It also increases the production capacity and reduces waste generated during the production process.
