Quantifying Charge Extraction and Recombination Using the Rise and Decay of the Transient Photovoltage of Perovskite Solar Cells
Krückemeier, L., Liu, Z., Kirchartz, T. and Rau, U. Adv. Mater. 2023, 35, 2300872 The extraction of photogenerated charge carriers and the generation of a photovoltage belong to the fundamental functionalities of any solar cell. These processes happen not instantaneously but rather come with finite time constants, e.g., a time constant related to the rise […]
