Abstract
- <?Pub Dtl?>This paper presents an organic sensor for ambient light monitoring fabricated on flexible plastic foil. The sensor exploits an organic photodiode whose photocurrent is linearly converted into an output voltage by a transconductance operational amplifier in a feedback configuration. The photodiode is based on an inkjet printed bulk heterojunction blend of P3HT/PCBM sandwiched between Au and Al electrodes, whereas the amplifier is implemented in a printed complementary organic TFT technology. Both the photodiode and the amplifier were fully characterized in stand-alone configuration. Then, the response of the assembled sensor was measured by using a commercial 12-V halogen lamp as light source. Experimental data demonstrated that the sensor is able to provide a linear detection of the incident light intensity up to 11000 lux. [ABSTRACT FROM PUBLISHER]
