Abstract

An ultraviolet (UV) photodetector utilizing an inkjet printable , UV photoconducting biopolymer was fabricated and the performance of the photodetector was characterized for varying thickness layers of the biopolymer. The biopolymer was formed of deoxyribonucleic acid (DNA), the Clevios P formulation of poly(3,4-ethylenedioxythiophene)- poly(styrenesulfonate) (PEDOT:PSS), and hexadecyltrimethyl-ammonium chloride (CTMA); this was then combined with phenyl-C61-butyric acid methyl (PCBM) to form the printable, UV photoconducting biopolymer. Using a 260-nm source, the highest measured responsivity of the photodetectors is 1.2 mA/W at 20 V bias.
