How does Thin Film Amorphous Silicon Solar work?
By having the ability to lay down three separate layers of amorphous silicon, each tuned to a different frequency of sunlight. This created a cell with three active semiconductor layers, called a “triple-junction” cell. The top active layer in a triple-junction cell captures a portion of the solar spectrum, and the remaining sunlight penetrates to the second layer, which captures another part of the solar spectrum, and likewise for the third and final layer. As a result, the cell converts more of the solar spectrum into electricity, achieving higher conversion efficiency. This technology works well on residential and commercial roofs as well.
