Organic multi-function diode with a function of light-emitting, photovoltaic, and color-sensing was demonstrated using a stack of 5,6,11,12-tetraphenylnaphthacene (rubrene) as an emitter/donor and N,N′-ditridecylperylene-3,4,9,10-tetracarboxylic diimide (PTCDI-C13) as an electron transporter/accepter. The device shows electroluminescent properties with a maximum luminance 840 cd/m2 with yellow emission based on rubrene, photovoltaic properties with power conversion efficiency 0.15% under AM1.5, and green color sensing with high on/off ratio over 104 under reverse bias of −1 V.
