Early developments laid the foundation, but recent innovations have pushed the technology forward. New material combinations and design improvements have enhanced efficiency and flexibility. These advancements address key limitations and open new possibilities for lightweight, cost-effective, and scalable solar energy solutions.
Plastic film is stepping out of its traditional role in packaging and into the spotlight of renewable energy. Researchers from the University of Sheffield and Power Roll have developed a groundbreaking innovation with flexible solar cells made with plastic film. These cells are embedded with perovskite, a mineral semiconductor known for its ability to convert sunlight into electricity efficiently. Unlike traditional silicon-based solar panels, these plastic film cells are lightweight, cost-effective, and adaptable. This breakthrough tackles high production costs and environmental concerns, making solar power more accessible while ensuring a sustainable future.

Traditional solar panels face significant limitations because they are heavy, rigid, and require energy-intensive manufacturing. Additionally, they rely on expensive and environmentally harmful materials like silicon and indium. Researchers have also identified stability, performance degradation, and large-scale production issues.
Plastic film solar cells address these challenges by offering a lightweight, flexible, and cost-effective alternative. Researchers create tiny grooves in plastic film and fill them with perovskite, efficiently capturing sunlight. Unlike earlier plastic solar cells, which struggled with stability and efficiency, this new design improves durability and reduces costs.
A stable internal structure is also essential for long-term performance. Previous studies explored adding inert polymers to optimize material composition and enhance efficiency. Building on this research, scientists have refined plastic film cells to improve structural integrity and simplify large-scale manufacturing.
Beyond technical improvements, plastic film solar cells offer greater versatility. Their flexibility allows installation on curved rooftops, fragile structures, and unconventional surfaces where traditional panels fail. As a result, this innovation expands solar energy access in remote or underserved areas. Professor David Lidzey from the University of Sheffield emphasizes, “This could be a game-changer for solar energy in low and middle-income countries.”

Plastic film solar cells provide benefits beyond flexibility. Their lightweight nature simplifies transport and installation, significantly reducing costs and logistical challenges. Perovskite, a solution-processable semiconductor, allows for scalable production through roll-to-roll manufacturing techniques. This method ensures high-volume production, making the technology commercially viable and accessible.
Another significant advantage is the back-contact design, where all electrical components are placed on the cell’s rear. This unique configuration allows the front surface to absorb more sunlight, boosting overall efficiency. Plastic film solar cells’ flexibility enables new applications, such as embedding solar power into building materials, wearable technology, and compact electronic devices. These features make them a versatile and practical solution for various energy needs.
The collaboration between the University of Sheffield and Power Roll has led to remarkable advancements in solar technology. Using advanced imaging techniques like X-ray microscopy, researchers can study the material composition of these solar cells in great detail. Moreover, this method helps identify structural variations, detect defects, and understand how different materials interact within the cell. By analyzing these details, scientists can improve efficiency, optimize material selection, and enhance long-term performance.
Moreover, this innovation aligns perfectly with global efforts to combat climate change. Plastic film solar cells can significantly reduce carbon emissions by replacing fossil fuels with clean, renewable energy. As Dr. Nathan Hill of Power Roll emphasizes, “We are advancing technology that could play a significant role in achieving global net-zero targets.”
Looking ahead, the next research phase will focus on optimizing the stability and performance of these cells. To achieve this, experiments scheduled for 2025 at the Diamond Light Source facility will provide deeper insights into the material’s behavior. In turn, these findings will help ensure long-term durability and efficiency. Ultimately, these studies will pave the way for the widespread adoption of this transformative technology.
The future of this technology is incredibly promising, as it can replace diesel generators in off-grid areas. Providing clean energy to remote communities reduces fossil fuel dependence while tapping into a £250 billion untapped market. This makes solar power more accessible and affordable worldwide, especially as sustainability gains momentum globally. Plastic film solar cells may soon become key enablers of smart infrastructure and energy-efficient urban solutions.
