Inks for the inkjet-deposition of Titanium dioxide and hybrid organic inorganic perovskites were synthesized and then used to deposit films for high efficiency perovskite solar cell devices. The inkjet-printed titanium dioxide electron transport layer was optimized in reference to state-of-the-art spin-coated tio2 films. After observing that the printed TiO2 films perform at least as well as the spin-coated version, this charge transport layer was used as the anode for inkjet-printed perovskite absorber layers. Using printed TiO2 and perovskite, 14.1% power conversion efficiency was achieved.
