Perovskite solar cells are the rising star in photovoltaics. They absorb light across almost all visible wavelengths, they have exceptional power conversion efficiencies exceeding 20% in the lab, and they are relatively easy to fabricate. So, why are perovskite solar cells yet to be found on the top of our roofs? One problem is their overall cost, and another is that cheaper perovskite solar cells have a short lifespan. A study published in Advanced Materials Interfaces by the Energy Materials and Surface Sciences Unit at the Okinawa Institute of Science and Technology Graduate University (OIST), reveals a cause for the short lifetime of perovskite solar cells with silver electrodes.
