Perovskite precursors and additives

Perovskite solar cells are hybrid inorganic-organic solar cells. Since the breakthrough in 2012 (Lee et al. Science 338, 643, 2012; Kim et al. Scientific Reports 2: 591, 2012), the technique has climbed quickly in efficiency to reach the current record of 25.2 %. Dyenamo offers two standard purity grades of salts for perovskite preparation; >99.99 % (grade 4N) and >99.999 % (grade 5N). In addition, we offer a special grade of methylammonium iodide (DN-P02P), based on 4N grade material, but containing a controlled amount of phosphite as an additive. Apart from the precursor salts, we offer a selection of additives to our precursor salts for improved perovskite compositions. Other purity-grades and/or other materials are available on demand, please contact us for such request. Likewise, please contact us for larger amounts than the ones displayed.

Further strategic Dyenamo material-components for perovskite solar cells can be found in the product categories: Hole transport materials and dopants, Carbon pastes, TiO2 and platinum pastes and FTO glass.
