Deleterious Effect of Negative Capacitance on the Performance of Halide Perovskite Solar Cells
Fabregat-Santiago, Francisco; Kulbak, Michael; Zohar, Arava; Vallés Pelarda, Marta; Hodes, Gary; Mora-Sero, Ivan American Chemical Society (2017)Negative capacitance in photovoltaic devices has been observed and reported in several cases, but its origin, at low or intermediate frequencies, is under debate. Here we unambiguously demonstrate a direct correlation ... -
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 ...
