Perovskite photovoltaics: stability and scalability
Submission status
Closed
Submission deadline
Perovskites are a promising class of materials in photovoltaics, having reached power conversion efficiencies of greater than 25%. However, their widespread application is still hindered by limited stability and difficulty in scaling up. This Collection showcases developments in perovskite research, from enabling larger-scale production to manufacturing more stable perovskite solar cells.
Perovskite solar cells must overcome the long-term stability problem in order to be put into practical use. Materials science, through the development of synthetic chemistry, materials characterization and device engineering can contribute to improvements in stability and scalability towards enabling large scale production. This Collection presents recent research efforts in stabilizing perovskite solar cells with three interconnected themes: characterizing instability, synthesizing stable perovskites and curing the interfaces.
