Abstract
Changes in processing conditions can yield different molecular structures and properties of organic materials.1,2 Photosensitivity is a property that characterizes several organic semiconductors, but their application as photoelectric converters or solar cells is limited because of the low efficiency of most of them.3,4 In fact their solar-cell efficiency is strongly influenced by their conductivity, particularly by the low mobility of the charge carriers (electrons and holes). In order to increase the mobility, denser and more effective electron intermolecular transfer structures should be developed. Centrifugal processing5 of these materials should be very promising because of the weak molecular bonding that characterizes organic materials, and because of the high molecular weight of organic semiconductors. Because of the low sublimation temperatures of many organic semiconductors,1,2 physical vapor transport (PVT) is a reasonable process to investigate.
