Organic-inorganic hybrid perovskite solar cells (PSCs) have experienced a rapid
development in the past few years, reaching a certified efficiency over 23%. The
semiconducting perovskite materials have shown great potential for photovoltaic
applications because of their outstanding optoelectronic properties. Meanwhile, two-
dimensional (2D) materials have attracted increasing attention due to their exceptional
chemical, electrical and physical properties. Recently, the synergic effects due to the …

Modern electronic and optoelectronic devices are formed by a sequence of layers in a
multimaterial/multijunction combination. Even Complementary Metal-Oxide Semiconductor
(CMOS) technology, dominated for many decades by silicon and its native oxide SiO2 is
moving toward a multimaterial structure where germanium (for strain engineering),
alternative oxides (for high dielectric constant insulators) and metal gates are efficiently
combined with silicon. Owing to the increased number of (hetero) junctions in these …
