“…The R value was very low, around 1.5 mA W −1 . However, a fast switching speed below 10 ms was achieved [77, 78]. In this study, a poly(4-phenoxy methylstyrene) (P4PMS) was employed as a gate insulating layer.…”

Recent progress in photoactive organic field-effect transistors (OFETs) is reviewed. Photoactive OFETs are divided into light-emitting (LE) and light-receiving (LR) OFETs. In the first part, LE-OFETs are reviewed from the viewpoint of the evolution of device structures. Device performances have improved in the last decade with the evolution of device structures from single-layer unipolar to multi-layer ambipolar transistors. In the second part, various kinds of LR-OFETs are featured. These are categorized according to their functionalities: phototransistors, non-volatile optical memories, and photochromism-based transistors. For both, various device configurations are introduced: thin-film based transistors for practical applications, single-crystalline transistors to investigate fundamental physics, nanowires, multi-layers, and vertical transistors based on new concepts.

“…[7][8][9] Meanwhile, organic photodiodes and phototransistors are drawing more and more research interests for their potential applications in light detection and signal magnification. [10][11][12][13][14][15][16][17][18] However, organic photoconductor, an equally important device for light detection, has not been extensively studied because it is very hard to improve its photocurrent. 19,20 The above-mentioned large binding energy seriously prevents exciton dissociation and promotes carrier recombination, 21,22 resulting in very small photocurrent in conventional lateral single-layer-single-material long-channel based photoconductors.…”

A trilayer architecture is designed for polymer photoconductors. In such a structure, photogenerated electrons in poly(3-hexylthiophene):[6,6]-phenyl-C61-butyric acid ethyl ester (P3HT:PCBM) blend film will flow into a TiOx layer beneath and then diffuse into a underlying PCBM layer. Photogenerated holes and electrons are thus efficiently separated by the spacer TiOx, and, respectively, transport in P3HT and PCBM films, carrier recombination is thereby greatly suppressed. As a result, photocurrent of the PCBM/TiOx/P3HT:PCBM trilayer structure increases more than 200 times over that of the conventional P3HT:PCBM single layer device.

“…It indicates an efficient charge transfer between the protein complexes and the electrodes where most of the photo-generated electrons are extracted from the electrode. 16 These results show superior performance compared to the previously reported work on similar systems where the waveform showed a nonsaturating profile with long rise and decay times in the order of minutes. [9][10][11] To evaluate the endurance of the photocurrent response, cycling stability test was performed by monitoring the photocurrent response as the device continuously cycled between dark and illuminated states.…”

Efficient light to energy conversion was demonstrated in solid-state, lateral photodiodes device containing photosynthetic light harvesting chlorophyll protein complexes as active materials. The device exhibits the highest reported photocurrent density response of 365 µA/cm 2 when illuminated at 320 mW/cm 2 radiation source power. The photocurrent response was stabled over 10 4 s of continuous cycles of dark and illumination states. The short rise and decay time of the photocurrent waveform within sub-second range indicates an effective photogeneration and charge extraction within the device. Optical bandgap extraction using absorbtion coefficient method reveals that the energy gap of the active materials ranges from 2.8 to 3.8 eV, correspond to the Photosystem I and Photosystem II of the photosynthetic pigmen-protein complexes.
