Researchers from the University of Surrey, University of Cambridge and University of Toronto, have explained the origin, characterization, pitfalls and opportunities for strain in perovskite materials. The team also explained their vision of how the research community can use strain to unleash the full potential of perovskite materials.
Dr. Wei Zhang, a corresponding author and Senior Lecturer from the University of Surrey, said: "Many in the photovoltaic research community are rightly excited about the potential of perovskite materials, not only when it comes to green technologies such as solar cells but other electronic devices. In this study, we look at factors that influence the efficiency and stability of devices—and explore the role strain may play on perovskites. A comprehensive understanding of strain in perovskites will lead to perovskite materials with remarkable optoelectronic novelty."
