Changes from Bulk to Surface Recombination Mechanisms between Pristine and Cycled Perovskite Solar Cells
Correa-Baena, Juan-Pablo; Turren Cruz, Silver Hamill; Tress, Wolfgang; Hagfeldt, Anders; Aranda Alonso, Clara; Shooshtari, Leyla; Bisquert, Juan; Guerrero, Antonio American Chemical Society (2017)Several aspects on the photophysical characterization of lead halide hybrid organic–inorganic perovskite solar cells remain unsolved. It has been observed that ionic transport and polarization of the interfaces cause very ... -
Effect of the chromophores structures on the performance of solid-state dye sensitized solar cells
Tian, Haining; Soto, Andrea; Xu, Bo; Sun, Licheng; Hagfeldt, Anders; Fabregat-Santiago, Francisco; Mora-Sero, Ivan; Kang, Yong Soo; Bisquert, Juan; Barea, Eva M World Scientific Publishing (2014)The effect of metal-free chromophores on dye-sensitized solar cell performance is investigated. Solid state dye-sensitized solar cells (ssDSCs) using different molecular sensitizers based on triphenylamine (TPA) with ... -
In Operando, Photovoltaic, and Microscopic Evaluation of Recombination Centers in Halide Perovskite-Based Solar Cells
Zohar, Arava; Kulbak, Michael; Turren Cruz, Silver Hamill; Nayak, Pabitra K.; Kama, Adi; Hagfeldt, Anders; Snaith, Henry J.; Hodes, Gary; Cahen, David American Chemical Society (2022-08-03)The origin of the low densities of electrically active defects in Pb halide perovskite (HaP), a crucial factor for their use in photovoltaics, light emission, and radiation detection, remains a matter of discussion, in ... -
Properties of Contact and Bulk Impedances in Hybrid Lead Halide Perovskite Solar Cells Including Inductive Loop Elements
Guerrero, Antonio; Garcia-Belmonte, Germà; Mora-Sero, Ivan; Bisquert, Juan; Kang, Yong Soo; Jacobsson, T. Jesper; Correa-Baena, Juan-Pablo; Hagfeldt, Anders American Chemical Society (2016)Impedance spectroscopy offers access to all the different electronic and ionic processes taking place simultaneously in an operating solar cell. To date, its use on perovskite solar cells has been challenging because of ... -
Science in the Age of Digital Networking
Bisquert, Juan; Hagfeldt, Anders; De Angelis, Filippo American Chemical Society (2015-08)Today, the world is moving fast, but we do not know exactly where this leads yet. As the economy of knowledge inevitably extends its tentacles on the realm of science, what are we –scientists- going to do? So far, an ... -
Thermodynamic stability screening of IR-photonic processed multication halide perovskite thin films
Sanchez, Sandy; Carlsen, Brian; Škorjanc, Viktor; Flores-Díaz, Natalie; Serafini, Patricio; Mora-Sero, Ivan; Schouwink, Pascal; Zakeeruddin, Shaik Mohammed; Graetzel, Michel; Hagfeldt, Anders Royal Society of Chemistry (2021-11-24)We report a material screening study for phase transitions of multication hybrid halide perovskite films. Two hundred sixty-six films processed with flash infrared annealing were optically and structurally characterized. This ...
