Artist Rendering of the Atomic Model of Organolead Trihalide Perovskite Crystals (IMAGE)
Caption
This is an artist's rendering of the atomic model of organolead trihalide perovskite crystals. Researchers have succeeded in growing high-quality single crystals of these perovskites at room temperature. The grown crystals efficiently convert light into charge-carriers that travel over very long distances, exceeding 10 micrometers, due to the crystalsπ exceptionally low concentration of defect trap-states. This study demonstrates that photovoltaics using organolead trihalide perovskite materials stand to see further breakthroughs through substantial improvement in material purity; it also suggests new avenues to deploy perovskites in an even wider range of semiconductor and optoelectronic device.
