“…Organic semiconductor thin films have great potential for low cost and large‐area flexible electronic and optoelectronic devices and have thus attracted a great deal of interest in the past decades. Recently, considerable achievements have been made with a variety of organic semiconductor thin films based on device architectures of photoconductors/phototransistors or photodiodes in the realm of flexible photodetectors . For example, Liu et al reported the realization of low‐voltage and high‐performance polymer thin‐film transistors (PTFTs) on flexible PET substrates with diketopyrrolopyrrole (DPP)‐based copolymers (PDQT and PDVT‐10) as channel semiconductors and n‐octadecyltrichlorosilane (OTS)‐modified poly(vinyl alcohol) (PVA) as a gate dielectric layer at low temperature .…”

Flexible photodetectors have attracted a great deal of research interest in recent years due to their great possibilities for application in a variety of emerging areas such as flexible, stretchable, implantable, portable, wearable and printed electronics and optoelectronics. Novel functional materials, including materials with zero-dimensional (0D) and one-dimensional (1D) inorganic nanostructures, two-dimensional (2D) layered materials, organic semiconductors and perovskite materials, exhibit appealing electrical and optoelectrical properties, as well as outstanding mechanical flexibility, and have been widely studied as building blocks in cost-effective flexible photodetection. Here, we comprehensively review the outstanding performance of flexible photodetectors made from these novel functional materials reported in recent years. The photoresponse characteristics and flexibility of the devices will be discussed systematically. Summaries and challenges are provided to guide future directions of this vital research field.

“…Nonetheless, when used in these kinds of devices, P3HT is not used alone, instead, it is usually reported in the specific literature in combination with other compounds, such as phenyl-C 61 -butyric acid methyl ester (PCBM) [7], organic dyes [8], TiO 2 nanoparticles [9], or carbon nanotubes [10].…”

In this article, we compare two different kinds of commercial light-emitting diodes (LEDs) in transmission and organic photodetectors based on poly(3-hexylthiophene) (P3HT) and a phenyl-C61-butyric acid methyl ester (PCBM) blend used as active layer in reception. Photovoltaic cells based on massive heterojunctions of semiconductor polymers have focused the attention of researchers due to their several potential advantages over their inorganic counterparts, such as their simplicity, low cost, and ability to process large area devices, even on flexible substrates. Furthermore, in logistics, storage management systems require the implementation of technological solutions that allow the control of merchandise in real time by means of light-emitting diode signals that send information about the product. However, the slow response time of these organic photodetectors should not be critical for this application, where the light intensity changes are very slow, which limits the speed of data transmission compared to inorganic based systems that use wireless optical communications. Finally, we show a low-cost visible light communication system based on organic photodetectors with a frame based on on-off keying with Manchester encoding to support device-to-device connections.

“…For these reasons, P3HT has become a good candidate for developing organic solar cells [ 5 ] and organic field effect transistors [ 6 ]. However, the use of P3HT for these devices, as well as photodetection applications, is usually reported in combination with other compounds, such as phenyl-C61-butyric acid methyl ester (PCBM) [ 7 ], organic dyes [ 8 ], TiO 2 nanoparticles [ 9 ] or carbon nanotubes [ 10 ].…”

This paper presents the electrical characteristics of solution-processed organic photodetectors based on poly(3-hexylthiophene-2,5-diyl) semiconducting polymer layers deposited by spin-coating on interdigitated metal electrodes. Four different electrode shapes have been used for this study in order to appraise the optimum electrode geometry. The measurement of the resistance as a function of the temperature reveals a transition from negative to positive temperature coefficient material around 80 °C for the polymer layers. Besides, slow reversible changes in the photodetectors conductivity were observed when moved from vacuum to the air and under illumination with a xenon lamp, which can be explained by the formation of charge transfer complexes with molecular oxygen and the polymer. The photogenerated current-light power ratio was found to be approximately linear in the 200 to 550 mW/cm2 range.
