Abstract

Solution-based deposition techniques and strategies to control the morphology of organic semiconductor thin films are reviewed and discussed.

Highlights

  • Many of the pioneering studies in the physics of organic semiconductors (OSCs) relied on vapor-grown crystals, there has been a signi cant interest recently in solution-based deposition techniques

  • The rapid advancement of thin lm solution processing methods and morphology control strategies during recent years has brought us closer to the bright future promised by organic electronics applications

  • It is clear that choosing the appropriate processing method and deposition parameters is at least as important as the choice of organic semiconductor material

Summary

Introduction

The goal of this review is twofold: (1) to survey and introduce a variety of solution-based deposition techniques commonly used in the industry and in research on organic electronics, and (2) to identify strategies used to tune the alignment and morphology of OSC thin lms. It is our hope that the methods described here can inspire both the application of these methodologies to other processing techniques and the development of new approaches for controlling these properties
