The performance of a printable, ultraviolet (UV) photoconducting biopolymer is investigated for UV photodetectors of varying layer thicknesses. The biopolymer is formed from deoxyribonucleic acid (DNA) with the addition of the Clevios P formulation of poly(3,4-ethylenedioxythiophene)-poly(styrenesulphonate) (PEDOT:PSS) and hexadecyltrimethyl-ammonium chloride (CTMA); it is then combined with phenyl-C61-butyric acid methyl (PCBM) to make a printable, UV photoconducting material. The highest measured responsivity of the photodetectors is 1.2 mA/W at 20 V bias using a 260 nm source.
