How Charge Carrier Exchange between Absorber and Contact Influences Time Constants in the Frequency Domain Response of Perovskite Solar Cells

PRX Energy, 2023
A model is derived for the frequency and time domain optoelectronic response of perovskite solar cells (PSCs) that emphasizes the role of charge carrier exchange, i.e., extraction and injection, from (to) the perovskite through the transport layer to ...
