Abstract in another language

Organometallic compounds as photoactive materials are relatively new in organic solar cells. Upon cyclometalation, the octahedral heteroleptic Ir complex TBzIr exhibits significantly enhanced optical-absorption and improved film-morphology compared to the planar organic 2-(5′′-hexyl-2{,}2′:5′{,}2′′-terthiophen-5-yl)benzodthiazole (TBz) ligand. Thus{,} a dramatically improved power conversion efficiency (PCE) from ∼0 to 3.81% is attained when combined with PC71BM.
