‘Radicalize’ the Performance of Perovskite Solar Cells with Radical Compounds
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.
