Yes, perovskite solar panels can indeed be integrated into flexible surfaces. Flexible perovskite solar cells (fPSCs) have rapidly evolved over the past decade, achieving power conversion efficiencies (PCE) of up to 25.1% and showing remarkable mechanical flexibility, making them well-suited for flexible applications.
Key points about perovskite solar panels on flexible substrates:
- Thin, light, and flexible profile: Perovskite solar cells are inherently thin and lightweight, enabling them to be adapted and applied on various flexible materials and curved surfaces.
- Substrate materials: Research has demonstrated perovskite solar cells fabricated on flexible polymer substrates such as polycarbonate films. Despite challenges such as surface roughness and chemical resistance, innovations like planarizing layers applied via blade coating have enabled the fabrication of durable, efficient flexible cells with PCEs around 13% and good mechanical resilience.
- Mechanical durability: Flexible perovskite solar cells have been shown to retain a significant portion of their initial efficiency (e.g., 72% after 5,000 bending cycles), highlighting their potential for repeated flexing and practical use in wearable or curved device applications.
- Manufacturing potential: Most layers of flexible perovskite solar cells, except electrodes, can be processed using low-temperature solution techniques compatible with low-cost, scalable manufacturing and integration with printed electronics.
- Applications: These flexible solar cells hold promise for wearable power supplies, building-integrated photovoltaics on curved surfaces, and integration into everyday products, pointing to a future where solar energy can be harvested from nearly any surface.
In summary, perovskite solar technology is not only efficient but also highly adaptable to flexible substrates, enabling integration into a wide range of flexible surfaces and devices. This flexibility, combined with improving efficiencies and durability, makes them a promising option for next-generation flexible solar energy harvesting.
