Fullerene/Silicon Hybrid Heterojunction diodes — •G. J. Matt¹, T. Fromherz², and N.S. Sariciftci¹ — ¹Linz Institute for Organic Solar Cells (LIOS), Johannes Kepler University Linz, Austria — ²Institute for Semiconductor and Solid State Physics, Johannes Kepler University, Austria

Fullerene based diodes on p-Si substrates are presented. Rectification up to 10⁵ at ± 1V is observed with broad spectral resolved photo-current in UV-Vis. Device parameter as the idealitay factor and the nature of the electronic structure at the Fullerene/Silicon heterojunction are discussed.
