Organic vapour-phase deposition (OVPD®) is used for the growth of the organic solar cell component materials such as the donor copper phthalocyanine (CuPc), the acceptor fullerene C60, and electron-conducting buffer layers of bathocuproine (BCP) on Si〈1 0 0〉 wafers and indium tin oxide (ITO) substrates on areas as large as 15×15 cm2. By means of X-ray diffraction (XRD) analysis we show that under continuous operating conditions the source materials possess long-term stability. The CuPc, C60and BCP thin film morphology and structure are characterised using scanning electron microscopy and XRD analysis. We demonstrate CuPc thin films with a highly folded surface morphology suitable for the preparation of solar cells with an interpenetrating donor-acceptor interface. The XRD diffraction patterns of the CuPc and C60layers deposited under conditions appropriate for the preparation of organic solar cells show spectra typical for these materials. Mixed CuPc:C60layers with controlled constituent ratios and layer thickness are deposited for the preparation of organic solar cells. First ITO/CuPc:C60/Al organic photovoltaic devices are prepared with an efficiency of ∼1% (conditions AM1.5). © 2007 Elsevier Ltd. All rights reserved.
