Thermal stability enhancement of perovskite MAPbI(3) film at high temperature (150 degrees C) by PMMA encapsulation

Methylammonium lead iodide (MAPbI(3)) is a perovskite material functioning as a light-absorbing layer in a perovskite solar cell (PSC). However, many works reported the poor thermal stability of MAPbI(3), which hindered the direct annealing of low-temperature processed (<= 150 degrees C) metal ox...
