Abstract
Organic solar cells (OSC), in spite of being a promising technology, still face challenges regarding large-scale fabrication. Although efficiencies of up to 12 % has been reached for small molecule OSC, their performance, both in terms of device efficiency and stability, is significantly reduced during up-scaling processes. The work presented here is focused on an approach towards up-scaling of small molecule based OSC with inverted device configuration. Bilayer OSC from Tetraphenyldibenzoperiflanthene (DBP) and Fullerenes (C70), as electron donor and acceptor respectively, with cell area ranging on a scale from a few mm2 to cm2, are produced by organic molecular beam deposition (OMBD). All the layers in the device are fabricated from a highly sophisticated vacuum cluster deposition system that includes electrode, interfacial layer and organic layer deposition in one high-vacuum deposition system. The work includes investigation of morphology and uniformity of the layers from atomic force microscopy (AFM) and optical spectroscopy investigations.
