Energy shortage is a global issue as fossil fuels deplete and energy consumption increases. Perovskite solar cells (PSCs) are a promising technology with comparable efficiency to traditional solar cells but lower fabrication costs. However, most PSCs research uses hazardous solvents unsuitable for large-scale production. This study successfully deposited PSC layers using a non-toxic solvent and ambient conditions, achieving high power conversion efficiencies.
Energy shortage has become a global issue in the twenty-firt century, as energy consumption grows at an alarming rate as the fossil fuel supply exhausts. Perovskite solar cells (PSCs) are a promising photovoltaic technology that has grown quickly in recent years. Its power conversion efficiency (PCE) is comparable to that of traditional silicon-based solar cells, and scale-up costs can be substantially reduced due to its utilization of solution-processable fabrication. Nevertheless, most PSCs research uses hazardous solvents, such as dimethylformamide (DMF) and chlorobenzene (CB), which are not suitable for large-scale ambient operations and industrial production. In this study, we have successfully deposited all of the layers of PSCs, except the top metal electrode, under ambient conditions using a slot-die coating process and nontoxic solvents. The fully slot-die coated PSCs exhibited PCEs of 13.86% and 13.54% in a single device (0.09 cm(2)) and mini-module (0.75 cm(2)), respectively.
