摘要：

Lateral structures have been used to characterize charge transport phenomena in organic bulk heterojunctions. Through the analysis of the current vs. voltage relationships and their light intensity dependence, space charge limited extraction currents and injection currents have been observed and characterized. Additionally, the drift length of charge carriers has been estimated by characterizing devices of varying lengths. These studies show that lateral structures are a promising way to study the basic physics of organic bulk heterojunction materials as they offer degrees of freedom unavailable in sandwich structures and such studies complement what can be learned from conventional sandwich structures.
