Preparation of PCBM Micro- and Nanoparticles via Electrohydordynamic Spray Route for Organic Photovoltaic Applications
Recently, organic electronic devices have been focused for its characteristic advantages, such as low process cost, flexibility, large process area and mass productivity. In this paper, we propose fabrication method of micro- and nanoaprticles which consists thin film via electrohydrodynamic spray route. 1-(3-methoxycarbonyl)-propyl-1-phenyl-(6,6)C61 (PCBM), often used as an electron acceptor, was dissolved in organic solvent, dichloromethane, and sprayed. The monodisperse particles were collected when the stable cone-jet mode was realized; however, the size of PCBM particles was coarse and ranged in several micro meters. The efforts to decrease the size of generated particles were conducted with controlling the experimental conditions, such as liquid flow rate, sampling distance, and solid fraction of solution. The final particle size was ranged in order of 100 nano meters.
