Photovoltaic and Electrical Properties of Diketopyrrolopyrrole Based Organic Semiconductors

POSTER

Abstract

Methylated-diketopyrrolopyrrole (MeDPP) is a small molecule, air-stable organic semiconductor with relatively high mobility, which is capable of undergoing excitonic singlet fission. Here we study the electrical transport and optical properties of MeDPP-based field effect transistors and photovoltaic devices. Using the magnetic field dependence of photocurrent in MeDPP solar cells we present strong evidence of efficient harvesting of charge carriers from triplet excitons. These results suggest that MeDPP is a promising candidate for high efficiency, air stable photovoltaic devices.
