Titanium oxide (TiO X ) is an effective electron transport layer (ETL) in polymer solar cells (PSCs). We report efficient inverted PSCs with a simple solution-processed amorphous TiO X (s-TiO X ) film as an ETL. The s-TiO X film with high light transmittance was prepared by spin-coating titanium (IV) isopropoxide isopropanol solution on indium tin oxide coated glass...
A red-emitting rubrene derivative, 2-formyl-5,6,11,12-tetraphenylnaphthacene (2FRb) was separately doped into 4,4′-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (NPB) and tris-(8-hydroxyquinoline) aluminum (Alq 3 ) as the emitting layer. The emission can be tuned from 580 nm to 607 nm in NPB host and 560 nm to 622 nm in Alq 3 host. The Alq 3 -hosted devices show better performances:...
