Making solar energy more efficient

Brandon Navas Dakota Guzman

How efficient is it really?

• Average solar cells only 10%-20% efficient

• High end solar cells can be 3-6 times more expensive

• High end solar cells only 18%-30% efficient

• Experimental cells proven to be 40% or more efficient

• Achieve this with nanocrystals (made from lead-selenium)

Solution

• Electrons travel along nanobot arms • Arms utilize nanocrystals makes them

60% efficient • Made from: -nanocarbon tubes

-Silver

Marketing

• Sell to top solar cell company(First Solar)• Package in osmium • Trucks and plans

Web Quest

1. Small technology 2. Nanotechnology is being used more than we

think. It is used in computers, medical field, machines, and memory chips.

3. We are making new “super hero” like materials. It can open new doors to computers, machines, technology, medicines, transportation, and many more.
