The past two years have seen the unprecedentedly rapid emergence of a new class of solar
cell based on mixed organic–inorganic halide perovskites. Although the first efficient solid …

Contemporary thin-film photovoltaic (PV) materials contain elements that are scarce (CIGS)
or regulated (CdTe and lead-based perovskites), a fact that may limit the widespread impact …

Solar cells based on organic–inorganic halide perovskites have recently shown rapidly
rising power conversion efficiencies, but exhibit unusual behaviour such as current–voltage …

The hybrid two-dimensional (2D) halide perovskites have recently drawn significant interest
because they can serve as excellent photoabsorbers in perovskite solar cells. Here we …
