Abstract: All-organic solution-processed two-terminal transistors were fabricated by replacing the “field-induced p-channel” of an organic field-effect transistor with a “photoinduced p-channel.” A simple device structure—containing solution-processed 2,6-di(naphthalene-2-yl)-9,10-bis(triisopropylsilylethynyl)anthracene single crystals as the active layer (on a plastic substrate) and poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) as source and drain electrodes—enabled high-performance photosensor (and even transistor) behavior, showing pseudo-output and transfer curves with an on/off ratio of 5×102. We explain this photogenerated p-channel effect using Helfrich’s theory, which describes the photodetrapping behavior of a space-charge-limited current under illumination.

Small molecular weight organic thin-film photodetectors and solar cells
TL;DR: In this paper, the double heterojunction was proposed to confine excitons within the active layers, allowing substantially higher internal efficiencies to be achieved, and a full optical and electrical analysis of the double-heterostructure architecture leads to optimal cell design as a function of the optical properties and exciton diffusion lengths of the photoactive materials.
