The rapid advancement of metal halide perovskites has
sparked interest
in strategies for manipulating their optoelectronic characteristics.
In the ambit of group III–V materials, multiple quantum well
(MQW) superlattices have previously demonstrated unique and advantageous
photophysical properties, driving record efficiencies in both photovoltaic
and light emission devices. Recently, perovskite-based MQWs have become
feasible, owing to significant progress in physical vapor deposition
techniques. In this Perspective, we outline the desirable optoelectronic
traits of MQWs, some observed in established semiconductors and the
few examples of perovskite-based ones. We elucidate the associated
advantages and explore their potential prospects. Finally, we discuss
some potential challenges that may be encountered in the pursuit of
seamless integration of perovskite MQWs into efficient devices.
