In this chapter, future prospects of perovskite solar cells development using solar energy and their opportunity and possible challenges during the large-scale energy production have been discussed. As the demand, the future of solar cells holds immense promise in revolutionizing energy production. The path way of the deployment of solar energy in future to achieve the target of sustainable goal up-to 2035 has been demonstrates. The review of research work done to improve the perovskite solar cell efficiency and future scope of work in milestone to design the solar cell have been summarized. The requirement of advancement in the solar cells as photovoltaic (PV) cells which has significant importance to enhance in efficiency, durability, cost reduction, and scalability at large scale has been discussed. The next-generation PV technology, perovskite-based solar cell, and their system offer to resolve efficiency and manufacturing cost problems against conventional energy sources. The technological challenges deterring the large-scale development of perovskite solar cells including intermittency, grid integration, storage solutions, and material sustainability have been discussed. The supportive policies, market incentive, and demand for the adoption of perovskite solar energy at large scale have been emphasized. The future scope of solar energy and possible solution of the challenges are described in details.
