Light-Induced Space-Charge Accumulation Zone as Photovoltaic Mechanism in Perovskite Solar Cells
American Chemical Society (2016)We fabricated formamidinium lead iodide perovskite solar cell for analysis of the photovoltaic mechanism based on the interpretation of the capacitance variation under illumination. It was shown that the low-frequency ... -
Potassium ions as a kinetic controller in ionic double layers for hysteresis-free perovskite solar cells
Royal Society of Chemistry (2019-07-22)Since ion migration and interaction with external contacts has been regarded as one of the origins for photocurrent density (J)–voltage (V) hysteresis and phase segregation in perovskite solar cells (PSCs) under operational ... -
Slow dynamic processes in lead halide perovskite solar cells. Characteristic times and hysteresis
American Chemical Society (2014-06)Characteristic times of perovskite solar cells (PSCs) have been measured by different techniques: transient photovoltage decay, transient photoluminescence, and impedance spectroscopy. A slow dynamic process is detected ...
