The
departure
of
Helmes,
who
joined
in
July
2010
amid
signs
that
Q-Cells’
fortunes
were
reviving,
is
effective
immediately
and
was
“by
her
own
request”,
says
the
company.
Chief
executive
Nedim
Cen
will
assume
the
additional
responsibilities
of
chief
financial
officer
–
a
dual
role
he
held
prior
to
Helmes’
hiring.
Chief
operating
officer
Andreas
von
Zitzewitz
will
take
over
the
additional
title
of
chief
sales
officer,
presently
held
by
Cen.
The
chaos
at
the
top
of
Q-Cells
–
the
world’s
largest
maker
of
PV
cells
until
2009
–
drove
the
German
company’s
share…
