Introduction: The Promise of Perovskite Solar Cells
Solar power has become one of the most reliable and renewable energy sources, with significant advancements in photovoltaic (PV) technology over the years. Silicon-based solar cells have dominated the market for decades, but newer technologies like perovskite solar cells are emerging as strong contenders due to their excellent photoelectric properties and potential for higher performance at lower costs.
Perovskite materials, particularly metal halide perovskites, have garnered attention due to their ability to achieve high power conversion efficiencies. Since the first PSCs were developed, their efficiency has risen dramatically, with the latest certified single-junction PSCs reaching an impressive 26.1%. This breakthrough marks a pivotal moment in the industrialization of PSCs.

Perovskite solar cells offer several advantages over silicon-based cells, including higher efficiency potential, lower production costs, and flexibility in design. These attributes make PSCs a highly promising technology for the future of solar energy.
Key Challenges in the Industrialization of PSCs
While PSCs show tremendous promise, the road to industrialization is not without its challenges. The review identifies several key areas that require attention for PSCs to become a viable and sustainable technology on a large scale.
1. Stability Issues
One of the most pressing concerns for PSCs is their long-term stability. While encapsulation technologies have helped to address issues related to water and oxygen exposure, PSCs still face challenges related to thermal and light stability. These issues can cause degradation and performance fluctuations, which are significant barriers to large-scale adoption.
2. Scaling Up Production
Another challenge is upscaling from small-area laboratory devices to large-area perovskite solar modules. The efficiency losses during this transition are significant, and much effort is needed to reduce the performance gap between laboratory-scale devices and their large-area counterparts.
3. Sustainability
As with any emerging technology, sustainability is a key consideration. The study highlights several strategies that can help reduce the environmental impact of PSCs, such as the use of green solvents, effective recycling methods, and encapsulation to protect the materials during their life cycle. However, these practices must continue to evolve to ensure that PSCs are not only a source of clean energy but also environmentally responsible.

Multi-Scenario Applications: Expanding the Reach of PSCs
The versatility of PSCs is another key strength. PSCs can be fabricated in various structures and sizes to suit different applications, from small-scale devices to large solar modules. The study discusses ongoing research aimed at optimizing these fabrication techniques to ensure that PSCs can be deployed in a wide range of scenarios. As research continues, PSCs are expected to be more widely used across various industries, further increasing their potential impact on renewable energy systems.
Conclusion: The Path Forward for PSCs
In summary, perovskite solar cells have made significant strides in terms of efficiency, positioning them as a strong contender in the renewable energy sector. However, their industrialization faces several key challenges related to stability, upscaling, and sustainability. Overcoming these obstacles will require continued research and technological development. The study concludes that with ongoing efforts to improve these areas, PSCs have the potential to play a significant role in the global energy transition, contributing to the widespread adoption of clean, renewable energy.
The findings of this review are critical for guiding the future development of PSCs and ensuring that they can be effectively integrated into various applications in the years to come.
