The Al2 O3 passivation layer is beneficial for mesoporous TiO2 -based perovskite solar cells when it is deposited selectively on the compact TiO2 surface. Such a passivation layer suppressing surface recombination can be formed by thermal decomposition of the perovskite layer during post-annealing.
当 Al2 O3 钝化层选择性地沉积在致密 TiO2 表面上时，有利于基于介孔 TiO2 的钙钛矿太阳能电池。这种钝化层可以通过钙钛矿层在退火后的热分解来形成，从而抑制表面复合。
