Perovskite solar cells

Crystal crosslinking

Nature Chemistry volume 7, pages 684–685 (2015)Cite this article

Subjects

Solid-state perovskite solar cells have recently emerged and have already reached efficiencies of 20%. Now, a simple solution-processing step that crosslinks neighbouring perovskite grain surfaces has been found to increase their stability, an important issue for future potential commercialization.

The emergence of perovskite solar cells undoubtedly represents one of the big scientific developments of the past few years. The highest certified solar-to-electrical power conversion efficiency of solid-state perovskite solar cells has rapidly risen to over 20% under 1 Sun (100 mW cm−2) illumination. Their high efficiency, together with their easier preparation procedures and lower cost of components, has made perovskite solar cells very competitive over other types of solar cell.
