Sharp of Japan has snagged another world record – by introducing
the world’s highest solar cell conversion efficiency which
stands at 36.9% thanks to a triple-junction compound solar cell.
This particular solar cell will feature a stacked three-layer
structure that keep sit going at such an energy efficient level.
Just how does compound solar cells work? Well, they make use of
photo-absorption layers that are made from compounds which
comprise of two or more elements (indium and gallium included).
Due to their high conversion efficiency, compound solar cells
tend to see action on space satellites most of the time. Guess
this new solar cell from Sharp might change things in time to
come. One of the key methods would be to reduce the resistance
of the junction areas necessary in order to hook up the solar
cell layers in series. This latest breakthrough was achieved
thanks to a research and development initiative that was
promoted by Japan’s New Energy and Industrial Technology
Development Organization (NEDO), h
