Abstract :
The influence of the light illumination on the drain current of polycrystalline silicon thin-film transistors is studied in this work. The increase of the output current as a result of raised light intensity is modeled, based on measured experimental data for different Vds and Vgs values. The proposed model has been verified against the measurements and the simulated output characteristics give a good approximation in the sub-threshold region
