Arizona-based CdTe
solar cell firm First Solar
expects to hit 12% efficiency in its thin film cells in the next
four years.
"We are currently on track to achieve our 2012 goal of 12%
conversion efficiencies. This represents an increase of
approximately 0.5% per year," spokesman David Erhart told
Electronics Weekly. "In Q1 2008 our average efficiency was
10.6%."
The firm mass produces solar cells, with over 300MW of its PV
modules installed worldwide at the end of 2007. It expects to ship
between 420 and 460 MW this year.
Amongst other projects, it is providing cells for the largest PV
power plant in the world: Germany's 40MW 'solar park' near Leipzig,
currently with 25MW installed, and a 4.6MW rooftop installation,
also in Germany.
Its latest contract is a 10MW plant in Nevada.
"We have more than 3.4GW contracted to our existing partners
from 2008-2012 representing approximately E4.9bn," said Erhart.
"Our customers design and develop PV power plants utilising our
modules and are active in Europe, Canada and the United
States."
Products are made in Ohio, with other factories under
construction. "First Solar will bring total expected capacity to
more than 1GW by the end of 2009," it said.
Partly due to its low cycle time - 2.5 hours from sheet of glass
to solar module - the firm claims to have the lowest manufacturing
cost per watt in the industry: $1.14/W (first quarter of 2008).
Claimed lifetime is long. "We offer a 25 year warranty for our
solar modules," said Erhart. "We warrant the modules will produce
at least 90% of their power output rating during the first 10 years
following their installation and at least 80% of their power output
rating during the following 15 years."
The firm also operates an end-of-life collection scheme. "With
the sale of each module, First Solar sets aside the funds required
for the collection and recycling in a restricted account controlled
by a third-party insurance company," said First.
