Small-molecule organic solar cells with a structure of indium tin oxide (ITO)\tris-8-hydroxy-quinolinato aluminum (Alq3) (2nm)\fullerene (C60) (40nm)\copper phthalocyanine (CuPc) (32nm)\Au (40nm) were fabricated. The shelf lifetime unencapsulated devices was over 1500h, and the power conversion efficiency reached 0.76% under AM1.5G (air mass 1.5 global) 75mW∕cm2. long attributed to inverted compared conventional ITO\CuPc\C60\buffer\Al since former could effectively protect C60 from diffusion...

Based on the WKB approximation of tunneling model, we calculate J–V characteristics organic light-emitting devices (OLEDs) having buffer layers different thickness. The results show how insertion a layer with proper thickness lowers OLED turn-on voltage. Further calculation suggests some parameters, such as resistivity ratio and position conduction band minimum relative to lowest unoccupied molecular orbital layer, are important in selecting material. A quantitative estimation optimal is...

A LiF-buffered silver cathode has been used in organic light-emitting devices (OLEDs) with structure indium–tin–oxide/N,N′-bis-(1-naphthl)-diphenyl-1,1′-biphenyl-4,4′-diamine (50 nm)/Alq3 (100 nm)/cathode. The efficiency of electron injection from the is strongly dependent on thickness LiF buffer layer. While a layer thinner than 1.0 nm leads to higher turn-on voltage and decreased electroluminescent (EL) efficiency, 3.0 significantly enhances results lower increased EL efficiency....

Tris (8-hydroxyquinoline) aluminum (Alq3)-based organic light-emitting devices using an amphiphilic molecule sodium stearate (NaSt) layer between (Al) cathode and Alq3 have been fabricated. By comparing the with those containing a LiF buffer layer, results demonstrate that both almost same high electroluminescent (EL) brightness but former is more stable. The property of NaSt considered as main reason for this enhancement.
