Thin-film’s
share
of
the
global
PV
market
has
fallen
from
nearly
20%
in
2009,
when
polysilicon
prices
were
sky
high,
to
less
than
10%
today,
and
the
share
is
“still
going
down”,
according
to
Finlay
Colville,
vice-president
of
market
researcher
Solarbuzz.
US-based
First
Solar
and
Japan’s
Solar
Frontier,
which
use
cadmium-telluride
and
copper
indium
gallium
selenide
(CIGS)
technologies,
respectively,
dominate
the
thin-film
sector.
But
in
both
cases,
a
large
share
of
their
production
is
being
fed
into
their
own
project-development
activities.
First
Solar
is
building
a
raft
of
mega-projects…
