The Material Science Behind Next-Generation Solar Energy
In short: How do we choose the right materials for thin-film photovoltaics? This MIT lecture explores the balance between technological potential, resource abundance, and environmental toxicity in modern energy production.
Professor Tonio Buonassisi examines specific thin-film technologies including amorphous silicon and copper indium gallium diselenide (CIGS). The discussion centers on critical manufacturing considerations such as material availability and the presence of toxic elements.
The lecture features a debate on Cadmium Telluride, questioning whether it represents a viable technology for the future or merely a 'red herring' in the pursuit of efficient solar energy.
