Cafe Sci 2: "Sustainable Energy from Sunlight: Advances in Solar Cell Tech"

Hello all.  Time again for Café Sci 2.  Here is the topic and presenter link: (topic outline below). We'll be on the 2nd floor of Brooklyn's.

Cafe starts at 6:30 and is usually done around 8:15. We always recommend you arrive by 6 (or earlier) for a good seat.  Also, the Café is open seating - any unoccupied chair is fair game.

Parking: should be free (or possibly $1) in Pepsi Center Lot A (aka 'Camry' lot), which is directly across from Brooklyns' front door - just south off Chopper Circle. ***If there happens to be a parking attendant, just tell them you're attending a science presentation at Brooklyn's.***

For those new to the group: this is not an official atheist meetup. Cafe Sci is open to the general public. However, folks from our group usually occupy the long rectangle of tables in the center of the room. If you don't know anyone, just ask if they're from the "meetup" group. Or you can come find me...I'll be on the far side of the room near the PA setup.

Please only RSVP "Yes"...this just gives us an idea of how many folks from our group are coming.


The sun is a promising source of renewable energy, due to the widespread abundance of sunlight and rapid advances in solar cell technology allowing us to capture and utilize that energy.  I will briefly discuss some background on the need for renewable energy, due to the finite availability of fossil fuels and their contribution to global climate change, as well as the needs of people in developing countries.  I will also give an overview of different potential sources of renewable energy, including the wind, tides, geothermal, as well as solar.  Then I will discuss the present status of solar energy, specifically concentrating on solar cells that convert sunlight directly to electricity.  I will give a taste of active research and development for better, more efficient, and cheaper solar cells; I'll present some of the work being done at the National Renewable Energy Lab, right here in the Denver area.  Finally, I welcome the audience to envision a more sustainable future, based on our choices and aided by technology such as solar cells.
