Abstract
Despite the purely inorganic Cu2AgBiI6 double perovskite being promising in thermal and moisture stability and environment friendly, the poor charge separation and non-radiative carrier recombination hamper its photo conversion efficiency (PCE). In this work, a ferroelectric polymer P(VDF-TrFE) is employed in the perovskite film of a solar cell with a co-crystalline process. The ferroelectric behavior of the perovskite film after the incorporation of P(VDF-TrFE) polymer is analyzed using Piezoresponse Force Microscopy (PFM). Through the ferroelectric polarization effect, both the short-circuit current (Jsc) and open-circuit voltage (Voc) are enhanced significantly enhanced. Consequently, the PCE is increased to 1.92%, which is one of the highest PCE recorded till date in Cu-based perovskite solar cells.Keywords
