The role of organic cations as additives in photovoltaic perovskites

Abstract

The design of additives for perovskite-based solar cells seeks to improve the balance between stability and power conversion efficiency. Organic molecules such as theophylline, theobromine and caffeine (xanthines) have proved...

Ecofriendly Solution Processing of Perovskite Solar Cells Using Water

“…Exploration of other effective organic ligands with demonstrated efficacy in conventional PSC fabrication may offer improved performance. 52 Moreover, water-based deposition methods in perovskite solar cell fabrication should not be limited to the Pb(NO 3 ) 2 /H 2 O system. Currently, Pb(NO 3 ) 2 is the most widely used lead source due to its high solubility in water (0.597 g/mL at 25 °C) and its facile reactivity with MAI to yield PbI 2 , as evidenced by prior studies.…”

“…Current research focus on inorganic additives in Pb(NO 3 ) 2 solution to adjust crystallization and growth kinetics. Exploration of other effective organic ligands with demonstrated efficacy in conventional PSC fabrication may offer improved performance . Moreover, water-based deposition methods in perovskite solar cell fabrication should not be limited to the Pb(NO 3 ) 2 /H 2 O system.…”
