stability mystery solved?

    This is potentially huge.

    A Japanese researcher has discovered that perovskite solar cell stability issues may be cause by tiny pin holes created when applying the materials to the cell.

    Perovskite Solar Cell Top Layer Covered in Pinholes

    Using atomic force microscopy (AFM), a researcher from the Okinawa Institute of Science and Technology (OIST) in Japan has discovered that the top layers of next-generation solar cells are covered in pinholes.

    Most of these promising, inexpensive devices are made from spiro-MeOTAD and perovskite. However, the perovskite layer deteriorates quicker, and the OIST discovery may finally reveal what the problem is. Pinholes in the spiro-MeOTAD layer allow water and gas molecules to enter, spread through the thin film and degrade the perovskite, significantly compromising the cell’s longevity.

    Abating the pinhole problem could pay off in optimizing these solar cells. “Since we already have quite high efficiency from perovskites solar cells, the only thing that we currently need is better stability and longer lifetime,” Hawash says. “And I believe that fixing the pinhole problem will do so, because these pinholes have several unwanted effects, including facilitating moisture or any other molecules from ambient air, migration through the doped spiro-MeOTAD film as well as facilitating the migration of some of the perovskite component elements to the top surface.”
