Perovskite solar cells (PSCs) have become a progressive photovoltaic technology because of their remarkable optoelectronic properties and superior power conversion efficiency (PCE). PSCs have made remarkable strides in scalability and PCE. However, this photovoltaic technology still faces several significant obstacles that need to be overcome before they can be widely used commercial applications. Enhancing compatibility with current industrial photovoltaic standards, addressing lead toxicity, creating scalable and economical manufacturing processes, and boosting long-term operational stability are some of these difficulties. This final chapter evaluate the development of PSC research, highlighting significant breakthroughs and pointing out outstanding issues. It offers a comprehensive viewpoint on the prospects and avenues for upcoming innovations, including investigating environmentally friendly and lead-free substitutes, incorporating perovskites with tandem architectures, and developing recycling and life-cycle assessment techniques. To support global renewable energy goals, this chapter aims to motivate researchers and stakeholders to close the gap between scientific discovery and the sustainable commercial deployment of PSCs by imagining these next steps.
