If moonshot was a race away
from our planet, SunShot, in a
way, is a race to save our planet.

Photovoltaics R&D
Dr. Rebecca Jones-Albertus
• Focus areas:
• New types of materials and device approaches that enable
higher PV performance, greater reliability and reduced cost
• Translational research and development to bridge gaps in
applied research with those in device and materials
development and manufacturing environment
• Has resulted in US leadership in PV R&D
• Over 50% of the world record solar cell efficiencies have been
supported by DOE funded researchers
• Supported the technology that is the foundation many
companies in the industry such as First Solar, SunPower, Suniva

Innovations in Manufacturing R&D (Tech to Market)
Dr. Lidija Sekaric
• Focus areas:
• Competitiveness Analysis
• Translating technology from
the laboratory to the
marketplace
• Manufacturing R&D to enable
US companies to compete
globally
• Resulted in tremendous
returns on US tax dollars

Unlike physics, where we can
fundamentally figure out the upper
limit for the efficiency of solar cells,
there is no such limit to bureaucracy

Rooftop Solar Challenge
energy.gov/sunshot
Well, let's say you can shave 10 seconds off of the boot time.
Multiply that by five million users and that’s 50 million seconds,
every single day. Over a year, that's probably dozens of
lifetimes. So if you make it boot ten seconds faster, you've
saved a dozen lives. That's really worth it, don't you think?
