Journal ArticleDOI
Cu2O Nanowire Photocathodes for Efficient and Durable Solar Water Splitting
TL;DR: A new synthetic method to grow Cu2O nanowire arrays on conductive fluorine-doped tin oxide substrates with well-controlled phase and excellent electronic and photonic properties is developed and an innovative blocking layer strategy is introduced to enable high performance.
Journal ArticleDOI
Efficient Inorganic Organic Hybrid Perovskite Solar Cells Based on Pyrene Arylamine Derivatives as Hole-Transporting Materials
Nam Joong Jeon,Jaemin Lee,Jun Hong Noh,Mohammad Khaja Nazeeruddin,Michael Grätzel,Sang Il Seok +5 more
TL;DR: This newly synthesized pyrene derivative holds promise as a HTM for highly efficient perovskite-based solar cells, comparable to that of the well-studied spiro-OMeTAD.
Journal ArticleDOI
Efficient panchromatic sensitization of nanocrystalline TiO2 films by a black dye based on a trithiocyanato-ruthenium complex
TL;DR: In this paper, a black trithiocyanato-ruthenium(II) terpyridylII complex was used to enhance the sensitization of nanocrystalline TiOI to solar cells.
Journal ArticleDOI
Thermal Behavior of Methylammonium Lead- trihalide Perovskite Photovoltaic Light Harvesters
TL;DR: In this article, the thermal properties of CH3NH3PbX3 (X = I or Cl) perovskite using thermogravimetric analysis were examined.
Journal ArticleDOI
The Significance of Ion Conduction in a Hybrid Organic–Inorganic Lead-Iodide-Based Perovskite Photosensitizer
Tae-Youl Yang,Giuliano Gregori,Norman Pellet,Norman Pellet,Michael Grätzel,Michael Grätzel,Joachim Maier +6 more
TL;DR: It is shown that methylammonium (but also formamidinium) iodoplumbates are mixed conductors with a large fraction of ion conduction because of iodine ions, providing insight into electrical charge transport in the hybrid organic-inorganic lead halide solar cells as well as into new possibilities of improving the photovoltaic performance by controlling the ionic disorder.
