The Photovoltaic Response of Intrinsic Organic Semiconductor Single Crystals
Department of Geological Sciences and Geotechnologies, Università degli Studi di Milano Bicocca, Piazza della Scienza 4, I-20126 Milano, Italy
ABSTRACT
Rubrene, perylene, α-quaterthiophene, and tetracene single crystals were grown and placed between indiumtin-oxide and Al electrodes; the current-voltage characteristics of the so-fabricated two-terminal organic devices were measured at ambient conditions under solar simulator illumination. While rubrene single crystals do not exhibit any photovoltaic effect, open-circuit voltages reach values up to 1.8 V in devices based on perylene, α-quaterthiophene, and tetracene single crystals.
