Colloidally prepared La-doped BaSnO₃ electrodes for efficient, photostable perovskite solar cells

Perovskite solar cells (PSCs) exceeding a power conversion efficiency (PCE) of 20% have mainly been demonstrated by using mesoporous titanium dioxide (mp-TiO₂) as an electron-transporting layer. However, TiO₂ can reduce the stability of PSCs under illumination (including ultraviolet light). Lanthanu...
