Organic Phototransistor

The effect of photoinduced electron transfer can be applied in organic phototransistors, as we demonstrated recently [146]. Spiro-DPSP 115 is a hole-transport material with a low charge carrier concentration in the dark. Under illumination, electron-hole pairs are generated that increase the munber of positive charges in the film, contributing to the conductivity. As a result, the transfer characteristic curve shifts toward lower switch-on voltages. [Pg.134]
