Research Abstract

pn-control techniques by impurity doping both for single and co-deposited films consisting of two kinds of organic semiconductors were established. A series of fundamental junctions such as Schottky junctions, pn-homojunctions, p^+, n^+/metal ohmic junctions, n^+p^+-ohmic homojunctions, and tandem cells were successfully fabricated in the co-deposited organic semiconductor films by impurity doping only. The present technique would offer the way for the fundamental improvement of efficiency of organic solar cells.
