摘　　要：Perovskite solar cells(PSCs)have attracted tremendous attention due to their outstanding performance within a short development.Radical molecules with unpaired single electrons have been widely used in energy-related fields,such as organic light-emitting diodes(OLEDs),organic field-effect transistors(OFETs),organic and dye-sensitized solar cells,batteries,thermoelectric conversion devices,etc.However,as far as we know,there has never been a systemic collection and analysis of the application of radical molecules in PSCs.Herein,we summarized the role of the radical molecule on perovskite(passivate trap defects,enhance oxygen stability and make perovskite band-bending)and charge transport layer(improve conductivity and mobility,enhance oxygen stability,modulate work function and decrease by-product generating).Meanwhile,future directions of making full use of radical molecules in improving the performances of PSCs were envisioned.
