Previous research into the new perovskite solar cells used a mesoscopic metal oxide that needs a high-temperature sintering process. Bolink’s group showed that by sandwiching methylammonium lead iodide perovskite layers between two thin organic charge-transporting layers using room-temperature fabrication processes they can also produce solar cells with high power-conversion efficiencies.
According to the researchers the cells can also be made semitransparent, which would allow them to be integrated into building facades. This would provide both UV protection to the building interior and also allow energy harvesting of the sunlight.
