Abstract: Disclosed is an electron transport layer for a flexible perovskite solar cell. The electron transport layer includes transition metal-doped titanium dioxide particles. The titanium dioxide particles are densely packed in the electron transport layer. The electron transport layer is transparent. The use of the electron transport layer enables the fabrication of a flexible perovskite solar cell with high power conversion efficiency. Also disclosed is a flexible perovskite solar cell employing the electron transport layer.
