  • Perovskite solar cell as a case of evidence-based policy
    • Shino Iwami, Project Researcher, University of Jyväskylä

    Correa-Baena et al. described to perovskite solar cell (1), which was picked up in the news as a candidate of the 2017 Nobel Prize in Chemistry (2).
    Perovskite solar cell is also a beneficial topic to evaluate implementations of evidence-based policy. I had paid my attention to perovskite solar cell and Prof. Miyasaka since my 2015 research that identified emerging sciences for evidence-based science and technology policy (3). Prof. Miyasaka’s group published the first paper from Japan in 2009, but other countries caught up with and exceed the first country. From the viewpoint of evidence-based policy and horizon scanning, Japan would had a chance to strengthen it in 2013-2014. However, the number of Japanese Grants-in-aid for Scientific Research about “perovskite solar cell” has a peak in 2015 (4). Continuous monitoring and forecasting are needed to keep the first-mover advantage as a domestic profit.
    The efficiency was still 16.2% (5) in 2015, but now it becomes 22 % (1). Perovskite solar cell seems to have a larger potential to be improve, according to (6). I expect it regardless of any countries' profit.
