Abstract:
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-state perovskite cells were reported only in
mid-2012, extremely rapid progress was made during 2013
with energy conversion efficiencies reaching a confirmed
16.2% at the end of the year. This increased to a confirmed
efficiency of 17.9% in early 2014, with unconfirmed values
as high as 19.3% claimed. Moreover, a broad range of
different fabrication approaches and device concepts is
represented among the highest performing devices —
this diversity suggests that performance is still far from
fully optimized. This Review briefly outlines notable
achievements to date, describes the unique attributes
of these perovskites leading to their rapid emergence and
discusses challenges facing the successful development
and commercialization of perovskite solar cells.
