Power Roll, Queen Mary Unite for Solar Film Breakthrough

• Power Roll and Queen Mary University revolutionize solar film quality control with cutting-edge optical analysis, paving the way for lighter, scalable, and eco-friendly solar solutions.

Power Roll, a solar start-up, has partnered with Queen Mary University of London to enhance quality control in the manufacturing of perovskite solar films. The collaboration focuses on addressing defects in perovskites using an "in-situ optical analysis" developed by Dr. Stoichko Dimitrov at Queen Mary. This technology provides rapid, accurate data for quality control, crucial for Power Roll's ultra-thin solar films, which are 25 times lighter than traditional silicon panels and challenging to inspect visually due to their microscopic size.

Dr. Dave Barwick from Power Roll highlighted the potential of this technology to expand solar applications without relying on rare materials. Dr. Dimitrov emphasized the real-time analysis of light interactions with the material, which will aid in scaling up production. The project, supported by Innovate UK, will also involve hiring a post-doctoral research associate to facilitate the transition from research to scalable production methods.

How will Power Roll and Queen Mary University improve perovskite solar film quality control?

• In-Situ Optical Analysis: The collaboration leverages an innovative "in-situ optical analysis" technique, which allows for real-time monitoring of the perovskite film production process. This method helps in identifying and rectifying defects at an early stage, ensuring higher quality and consistency in the final product.
• Enhanced Defect Detection: By focusing on the interaction of light with the perovskite materials, the technology can detect microscopic defects that are not visible to the naked eye. This capability is crucial for maintaining the integrity and performance of the ultra-thin solar films.
• Scalability and Efficiency: The real-time data provided by the optical analysis enables more efficient scaling of production processes. This is particularly important for Power Roll as they aim to produce large volumes of solar films without compromising on quality.
• Material Efficiency: The technology supports the use of less material by ensuring that each layer of the perovskite film is optimally produced. This aligns with Power Roll's goal of creating lightweight solar solutions that do not rely on rare or expensive materials.
• Post-Doctoral Research Associate: The project includes the hiring of a post-doctoral research associate, who will play a key role in bridging the gap between laboratory research and industrial-scale production. This position will focus on refining the quality control processes and integrating them into Power Roll's manufacturing line.
• Innovate UK Support: The collaboration is backed by Innovate UK, which provides funding and resources to support the development and commercialization of innovative technologies. This support is instrumental in accelerating the transition from research to market-ready products.
• Broader Solar Applications: By improving the quality control of perovskite solar films, the partnership aims to expand the range of applications for solar technology. This includes potential use in areas where traditional silicon panels are not feasible due to weight or flexibility constraints.
• Environmental Impact: The development of high-quality, lightweight solar films contributes to the broader goal of reducing the environmental impact of solar panel production. By minimizing material use and enhancing efficiency, the collaboration supports sustainable energy solutions.
