Deleterious Effect of Negative Capacitance on the Performance of Halide Perovskite Solar Cells
(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 ...
Overcoming Charge Collection Limitation at Solid/Liquid Interface by a Controllable Crystal Deficient Overlayer
Bulk and surface charge recombination of photoelectrode are two key processes that significantly hinder solar-to-fuel conversion of photoelectrochemical cell (PEC). In this study, the function of a “crystal-deficient” ...
Surface Polarization Model for the Dynamic Hysteresis of Perovskite Solar Cells
(American Chemical Society, 2017-02)
The dynamic hysteresis of perovskite solar cells consists of the occurrence of significant deviations of the current density–voltage curve shapes depending on the specific conditions of measurement such as starting voltage, ...
