In this case the researchers worked with methylammonium lead iodide
, a common material in perovskite PV research.
Now, the lab of Mohammad Khaja Nazeeruddin at EPFL Valais Wallis, with colleagues at the University of Cordoba, has discovered that they can improve perovskite stability by introducing the large organic cation guanidinium (CH6N3+) into methylammonium lead iodide
perovskites, which are among the most promising alternatives in the group today.
On a less optimistic note, researchers of the Energy Materials and Surface Sciences Unit at the Okinawa Institute of Science and Technology Graduate University have been studying the short lifespan of methylammonium lead iodide perovskite ([MAPbl.
We found that these PSCs are self-exposed to iodine vapor at the onset of degradation, which led to accelerated decomposition of the perovskite material into lead iodide," Wang explains.

Professor Hyatt and his team created a solid material for immobilisation of iodine with the formula Pb5(VO4)3I, by heating a mixture of lead iodide
, lead oxide and vanadium oxide.
However, one team did get unusual lead iodide
crystals from space experiments conducted two years ago (SN: 9/23/89, p.
Lance Wheeler is the lead author of the paper, Switchable Photovoltaic Windows Enabled by Reversible Photothermal Complex Dissociation from Methylammonium Lead Iodide
, published in Nature Communications.
The scientists fabricated the new solar cell by drop-casting a solution of lead iodide
, methylammonium iodide, and 5-ammoniumvaleric acid iodide through a porous carbon film.
Scientists first attempted to goad rain from the sky with silver and lead iodide
in the 1940s.
crystals grown last year aboard the space shuttle Discovery show unexpected differences from those produced on Earth with identical techniques, reports Steven L.
The research team blended methylammounium lead bromide with formamidinium lead iodide
to achieve an efficiency of 17.
