Efficiency limits of perovskite solar cells with n-type hole extraction layers
Efficiency limits of perovskite solar cells with n-type hole extraction layers
Transition metal oxides (TMOs) like MoOx are increasingly explored as hole transport layers for perovskite-based solar cells. Due to their large work function, the hole collection mechanism of such solar cells are fundamentally different from other materials like PEDOT: PSS, and the associated device optimizations are not well elucidated. In …
