Sharp Develops a Solar Cell with the World’s Highest Conversion Efficiency of 35.8%.

Sharp Corporation has achieved the world’s highest solar cell conversion efficiency of 35.8% using a triple-junction compound solar cell.

Unlike silicon-based solar cells, the most common type of solar cell in use today, the compound solar cell utilizes photo-absorption layers made from compounds consisting of two or more elements such as indium and gallium. Due to their high conversion efficiency, compound solar cells are used mainly on space satellites. Since 2000, Sharp has been advancing research and development on a triple-junction compound solar cell that achieves high conversion efficiency by stacking three photo-absorption layers.

To boost the efficiency of triple-junction compound solar cells, it is important to improve the crystallinity (the regularity of the atomic arrangement) in each photo-absorption layer (the top, middle, and bottom layer). It is also crucial that the solar cell be composed of materials that can maximize the effective use of solar energy.

    Always the same. All these companies announce breakthrough technology but they never follow up with an announcement of an actual product I could buy.

    When (if at all) will this great new solar cell become a solar panel I can order? And for how much $$$€€€?

    Oh, well. Sanyo or Kyocera is gonna have to be, as they SELL stuff and not just announce they can make it.
