Photovoltaic cells can transform light energy into electrical power [2]. Perovskites made on organic-inorganic lead halide are highly desirable in photovoltaics due to their affordability in production. A broad spectrum of light can be absorbed and suitable bandgap for fabricating semiconductor devices ...
paradigm is urgently required, driving innovations in architectures, materials, and processes to continuously improve energy efficiency and operation speed to meet the exponentially growing computing power demand. In recent years, the advent of memristors has unlocked transformative opportunities for performing...

Herein, this approach to adjust the offsets of the energy levels of the perovskite is demonstrated. To prepare the perovskite films with embedded PbS QDs, the organic capping of QDs is exchanged by a halide perovskite shell. Film properties are correlated to the structural changes of the soft ...

However, the optoelectronic performance of LED devices based on perovskite NCs is severely limited by the problem of charge injection since (i) the charge injection layers exhibit significant differences in energy levels and charge mobility, (ii) one thick NCs emitting layer can obstruct the ...
