3rd Generation Technology
The III-V design is important because this element combination has the highest known theoretical efficiency - with the ability to reach efficiencies upwards of 70% due to band-gap utilization expansion with hetero-junctions.
Should solar become cost competitive with other power generation technology - reaching the so-called “power parity” - the potential is massive. In 2011, $371 billion was spent on the purchase of electricity in the United States alone.
“The most efficient semiconductors in solar cells are alloys made from elements from group III of the periodic table, like aluminum, gallium, and indium, with elements from group V, like nitrogen and arsenic.”.
