perovskite

Avoiding buried voidsThe buried interfaces of perovskite solar cells are difficult to alter after synthesis. During manufacture, Chen et al. removed perovskite films with dimethyl sulfoxide solvent from the hole-transfer layer and observed…

Evening out the heatThe conversion of precursors into the active layer of perovskite solar cells normally occurs by heating the underlying substrate. Conversion tends to occur near the top of the film, where solvent is lost, and unwanted…

Suppressing nucleation over large areasAlthough formamidinium-based lead iodide (PbI2) perovskites have a favorable bandgap and good thermal stability, the difficulty in controlling nucleation makes it difficult to grow high-quality,…
