Over the past 10 years, a tremendous amount of work has been published in the area of organic single crystals. The ability to extract the intrinsic charge transport properties from these molecular solids has enabled scientist to have a deeper understanding of the performance limitations in organic semiconductors. This symposium presentation will focus and honor Professor Zhenan Bao and her efforts on semiconductor crystals over the past several years. The first half of the presentation will highlight our collaborative work and the second half will focus on my independent research. Specifically, I will focus on new phenomana and applications of organic single crystals (Figure 1. Wrinkled rubrene crystal on PDMS) and also on interfacial crystallization- a new method of growing oriented vertical crystals for achieving the ideal architecture for organic solar cells. We employ graphene monolayer films as substrates for observing the evolution of growth and molecular orientation of organic semiconductor thin films. These interfaces offer a promising route towards understanding how to develop highly efficient photovoltaics, but also allow for fundamental structural studies to be carried out.
