Charge carrier mobility in different donor materials for polymer solar cells — •Oleisa Synooka, Chetan Raj Singh, Marco Seeland, Gerhard Gobsch, and Harald Hoppe — Institüt für Physik, TU Ilmenau, Weimarer str.32, 98693 Ilmenau, Germany

Abstract: During recent years, many donor materials of varying band gap have been synthesized for polymer solar cell applications. Here, we compare the charge carrier mobilities of different commercially available p-type materials (e.g. P3HT and- PCDTBT) by the Space Charge Limited Current (SCLC) method. The mobility measurement results from SCLC are compared with Charge Extraction by Linearly Increasing Voltage (CELIV) measurements. Furthermore, several anode materials (e.g. PEDOT:PSS) have been investigated and compared with respect to their charge injection behavior.
