已经展示了通过喷墨和气溶胶喷射印刷在纸基板上制造的多层聚合物光电探测器。它采用聚（3-己基噻吩）和 C61-丁酸甲酯混合物（P3HT:PCBM）作为夹在银底部电极和聚（3,4-乙烯二氧噻吩）：聚（苯乙烯磺酸）（PEDOT:PSS）顶部电极之间的光活性层。 P3HT: PCBM 和 PEDOT: PSS 顶部电极之间的脱氧核糖核酸生物聚合物夹层能够在 P3HT: PCBM 上打印 PEDOT: PSS。当中心波长分别为 405、465、525 和 635 nm 的四种不同的发光二极管光激发时，印刷光电探测器表现出光响应。在 405 nm 处观察到最高响应度。对脉冲光的响应度显示出 25 至 1000 Hz 之间的强烈频率依赖性。
A multilayer polymeric photodetector fabricated on a paper substrate by inkjet and aerosol jet printing has been demonstrated. It employs a poly(3-hexylthiophene) and C61-butyric acid methyl ester blend (P3HT:PCBM) as a photoactive layer sandwiched between a silver bottom electrode and a poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) top electrode. A deoxyribonucleic acid biopolymer interlayer between P3HT: PCBM and PEDOT: PSS top electrode enables the printing of the PEDOT: PSS on P3HT: PCBM. The printed photodetector exhibits a photoresponse when photoexcited by four different light emitting diodes with center wavelengths of 405, 465, 525, and 635 nm. The highest responsivity was observed at 405 nm. The responsivity to pulsed light reveals a strong frequency dependence from 25 to 1000 Hz.
