Perovskite solar cells (PSCs) are gaining attention as next-generation solar cells owing to their lightweight design and high-power conversion efficiency. However, improving their durability and establishing cost-effective manufacturing processes are crucial challenges for widespread adoption. To address these issues, advancements must be pursued from both mass-production and on-demand manufacturing perspectives. The development of PSC originated from research on dye-sensitized solar cells (DSSCs) using plastic films. The integration of halide perovskites with titanium oxide electrodes demonstrated efficient power generation. Our research on low-temperature fabrication methods for roll-to-roll printing has contributed to PSC innovations. The lightweight and flexible nature of PSCs, which allows for their installation on curved surfaces, significantly expands their potential for solar power generation. Installing these systems on buildings aligns with the concept of transforming urban environment into energy-generating spaces. Furthermore, their application in indoor light harvesting and integration with IoT devices opens new possibilities for energy-saving technologies. Thus, PSCs are expected to play a key role in decentralized energy systems and self-sufficient societies. Further research is required to develop sustainable and cost-effective PSCs. In addition, PSCs are recognized as a technology that enables individuals to achieve energy self-sufficiency. Therefore, the development of flexible solar cells using plastic substrates is crucial for achieving a decarbonized society. Printing technology is envisioned as a foundational technology supporting the advancement of carbon-neutral solutions.
