Materials and methods for cost-effective fabrication of perovskite photovoltaic devices

Although perovskite solar cells (PSCs) are promising next generation photovoltaics, the production of PSCs might be hampered by complex and inefficient procedures. This Review outlines important advances in materials and methods for the cost-effective manufacturing of PSCs, including precursor synthesis, selection criteria for precursors based on chemistry, additive engineering, and deposition techniques. The goal of these technologies is not only to improve the performance and stability of PSCs, but also to significantly reduce their manufacturing costs. These advances are critical to the commercialization of PSCs, in terms of making them viable and cost-effective. The scalable and cost-effective synthesis of perovskite solar cells is dependent on materials chemistry and the synthesis technique. This Review discusses these considerations, including selecting a suitable perovskite pre-cursor, additive engineering, and the deposition process.
