Proof-of-concept for facile perovskite solar cell recycling

Ulf Anders Hagfeldt, Joachim Maier, Fabrizio Giordano, Othmar Müntener, Norman Pellet, Jeannette Medina Kadro

Perovskite solar cells based on CH3NH3PbI3 and related materials have reached impressive efficiencies that, on a lab scale, can compete with established solar cell technologies, at least in short-term observations. Despite frequently voiced concerns about ...

Phonon Mode Transformation Across the Orthohombic-Tetragonal Phase Transition in a Lead Iodide Perovskite CH(3)NH(3)Pbl(3): A Terahertz Time-Domain Spectroscopy Approach

Jeannette Medina Kadro

We study the temperature-dependent phonon modes of the organometallic lead iodide perovskite CH3NH3PbI3 thin film across the terahertz (0.5-3 THz) and temperature (20-300 K) ranges. These modes are related to the vibration of the Pb-I bonds. We found that ...

Loading of mesoporous titania films by CH3NH3PbI3 perovskite, single step vs. sequential deposition

Michael Graetzel, Carole Graetzel, Thomas Moehl, Jeannette Medina Kadro

Infiltration of mesoporous TiO2 scaffolds by CH3NH3PbI3 is more complete when using sequential compared to single step deposition processing and avoids formation of disordered capping layers affording greatly improved performance of perovskite based photov ...

Facile route to freestanding CH3NH3PbI3 crystals using inverse solubility

Michael Graetzel, Ulf Anders Hagfeldt, Kazuteru Nonomura, Jeannette Medina Kadro

CH3NH3PbI3 was found to exhibit inverse solubility at high temperatures in gamma-butyrolactone. Making use of this unusual, so far unreported phenomenon, we present a facile method for the growth of freestanding crystals of CH3NH3PbI3 from solution without ...

Synthesis and crystal chemistry of the hybrid perovskite (CH3NH3) PbI3 for solid-state sensitised solar cell applications

Michael Graetzel, Jeannette Medina Kadro

The hybrid organic-inorganic perovskite (CH3NH3) PbI3 may find application in next generation solid-state sensitised solar cells. Although this material and related perovskites were discovered many decades ago, questions remain concerning their diverse str ...
