We are living in a material world, and I am a material … scientist
David Moore (Staff scientist, NREL)
In this talk I’ll tell you what Materials Science is, why it’s important, what we do with it and how it changes your everyday world. I’ll focus specifically on materials science for renewable energy generation and give several examples of how the work we’re currently doing is already, and will continue, to change how we all live. Or, I’ll tell a bunch of funny science stories and make things blow up.
Silicon Photovoltaics: From Earth Abundance to High Efficiency
Vincenzo LaSalvia (Process engineer, NREL)
The vast majority of global market sales for solar panels are made from crystalline silicon. Silicon, found in sand, is the second most abundant element in the earth’s crust making it a readily available and non-toxic resource for solar energy production. However, in order to go from ultrapure sand to semiconductor grade silicon requires some significant and often energy-intensive engineering. In this edition of Pint of Science, I’ll discuss the fundamental concepts of converting silicon-rich sand into solar grade crystalline silicon.
