Researchers reveal their progress in solvent engineering to help achieve the highest quality for perovskite light-absorbing layers.
Perovskite solar cells are extensively studied and developed as they have high power conversion efficiency and are easy to manufacture. They can deliver high performance under low-temperature solution-based fabrication processing, which allows materials to be dissolved in suitable solvents to produce inks. There are several challenges remaining such as producibility of high-quality, scalable perovskite thin film preparation.
Researchers from Surrey’s Advanced Technology Institute (ATI) reported their progress in solvent engineering to help achieve the highest quality for perovskite light-absorbing layers. Their work is published in the journal Small. The paper focuses on the essential characteristics of the developed solvent systems and the engineering methods for perovskite thin film preparation, and how this progress is paving the road for future revolution in solar cell devices and their inks.
Dr. Ehsan Rezaee, postdoctoral research fellow at the ATI at the University of Surrey, said, “The emergence of perovskite solar cells as the highly efficient new generation of solar harvesting technology is incredibly exciting. However, while their flexibility, lightweight nature and semitransparency are all pluses, there are fundamental challenges to address if they are ever to be commercially viable.
“High-throughput and large-scale industrial manufacturing of perovskite thin films depends on the successful development of both fabrication techniques and suitable inks. We hope our roadmap sets the course for these promising materials to reach their full potential.”
