Perovskite solar cells from lab to fab: the main challenges to access the market

Research progress in the field of perovskite solar cells highlights perovskite-based photovoltaic as a very promising candidate for future energy technologies. Despite the number of advantages, perovskite solar cells still remain within laboratories. Several critical issues need to be solved before perovskite solar cell technology enters the industrial stage and will undergo the commercialization process. This review summarizes current challenges in the commercialization of the perovskite solar cells and discusses possible solutions to overcome these issues. The review is focused on scaling up of the perovskite technologies, development of industry compatible manufacturing, selection of functional materials and solvents suitable for mass manufacturing. Moreover, the stability of the cells and modules, as a critical condition for future commercialization, is also discussed in this review. Special attention is paid to the stability of the modules and identifying specific aspects that differentiate the stability of cells and modules. The environmental aspects and lead toxicity are also discussed among the challenges for the commercialization of perovskite solar cells.
