National Institute of Technology, Oyama College 1 article published in JoVE Engineering Morphology Control for Fully Printable Organic–Inorganic Bulk-heterojunction Solar Cells Based on a Ti-alkoxide and Semiconducting Polymer Takehito Kato1, Chihiro Oinuma1, Munechika Otsuka1, Naoki Hagiwara2 1Department of Mechanical Engineering, National Institute of Technology, Oyama College, 2Ashizawa Finetech Ltd. A method for fully printable, fullerene-free, highly air-stable, bulk-heterojunction solar cells based on Ti alkoxides as the electron acceptor and the electron-donating polymer fabrication is described here. Moreover, a method for controlling the morphology of the photoactive layer through the molecular bulkiness of the Ti-alkoxide units is reported.
