First Solar and Intermolecular Announce Joint Program to Accelerate Solar PV Roadmap

Collaboration Will Leverage Intermolecular's High Productivity Combinatorial Platform Towards Achieving Higher CdTe Solar Panel Efficiencies

TEMPE, Ariz and SAN JOSE, Calif., June 11, 2012 First

Solar, Inc. (Nasdaq:FSLR) and Intermolecular, Inc. (Nasdaq:IMI) today
announced a collaboration and licensing agreement aimed at accelerating the
efficiency roadmap for First Solar's cadmium-telluride
(CdTe) photovoltaic (PV) technology. First Solar is the world's largest thin
film PV solar module manufacturer and the leader in thin film PV
utility-scale solar power plants.

Under a newly signed collaborative development program, First Solar will
leverage Intermolecular's High Productivity Combinatorial (HPC) platform in
the development of its advanced, CdTe-based, thin film PV manufacturing
technology. The program addresses new opportunities in certain critical
materials and processes that may significantly influence the conversion
efficiency of CdTe technology. Technical work is to be performed jointly at
Intermolecular's San Jose, Calif., facility and in First Solar's research
and development labs.

"We are excited to engage in this ongoing collaboration with
Intermolecular," said Raffi Garabedian, First Solar Chief Technology
Officer. "Further improving our world-record CdTe conversion efficiencies
remains a strong lever to reduce the cost of solar energy.
We evaluated Intermolecular's HPC platform and technical team in a trial
collaboration, and this experience confirmed the suitability of the platform
for our purposes."

First Solar set a new world record for CdTe PV solar module efficiency in
January 2012, achieving 14.4 percent total area efficiency. In July 2011,
the company set a world record for CdTe PV cell efficiency at
17.3 percent. Both records were confirmed by the U.S. Department of Energy's
National Renewable Energy Lab (NREL).

Craig Hunter, Intermolecular's senior vice president of Global Sales &
Marketing, commented, "Leveraging our HPC platform to accelerate the PV
roadmap is central to our mission at Intermolecular. Today's announcement
with First Solar -- a market leader in PV and the undisputed champion in
thin film PV -- represents tremendous validation of that proposition,
particularly given the extensive technical due diligence the First Solar
team conducted prior to entering into this agreement."

Intermolecular's mission is to improve R&D efficiency in the semiconductor
and clean-energy industries through collaborations that use its HPC
platform, which allows R&D experimentation to be performed at speeds up to
100 times faster than traditional methods.
