The origin of the bulk photovoltaic effect (BPVE) was considered as a built‐in electric field formed by the macroscopic polarization of materials. Alternatively, the “shift current mechanism” has been gradually accepted as the more appropriate description of the BPVE. This mechanism implies that the photocurrent generated by the BPVE is a topological current featuring an ultrafast response and dissipation‐less...
