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

The SunShot Portfolio
energy.gov/sunshot
Concentrating Solar Power Dr. Ranga Pitchumani
• Focus areas: • Solar Field• Receiver• Thermal fluid/storage• Power Block
• Has led to commercialization of the largest CSP plants in the world
energy.gov/sunshotenergy.gov/sunshot 18
2010 & 2013 CSP Baselines and SunShot Goal
• Note: assumes no ITC. $2013 converted to $2010 using the “Chemical Engineering Plant Cost Index.“
• 8 ¢/kWh reduction in LCOE (38%) from 2010 to 2013• An additional 7 ¢/kWh (54%) LCOE reduction still necessary to
achieve SunShot goals

Photovoltaics R&DDr. 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 (>$1.7B)
Long-Run U.S. Manufacturing Opportunities

SolarMAT: Manufacturing and Supply Chain Technology R&D
• High Impact Technologies• Technologies which provide
cost reductions and performance improvements with broad application across the industry
• Strengthen the domestic PV industry
• Technologies developed under this program can be adopted directly into current manufacturing processes

there is no such limit to bureaucracy

Rooftop Solar Challenge
energy.gov/sunshotenergy.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?
