BRISTOL:
ANL
has
been
working
to
refine
the
design
of
a
so-called
hybrid
solar
cell
-
in
which
less-expensive
organic
and
inorganic
semiconducting
materials
are
combined
to
create
electricity
-
that
would
solve
many
of
the
shortcomings
hampering
commercialisation
of
current
hybrid
technologies.
"The
potential
of
solar
power
will
always
be
limited
until
its
levelised
cost
of
energy
is
equivalent
to,
say,
coal,"

ANL
assistant
scientist
Seth
Darling.
"So
the
challenge

-
given
that,
generally
speaking,
the
low-cost
materials
and
processes
are
too
inefficient
in
terms
