Gallery: Semprius’ Stacked Solar Cells Could Make Solar Energy Cheaper ...

By stacking solar cells, the cost of solar power could fall dramatically

Two of the main obstacles to the widespread adoption of solar energy are cost and efficiency. However researchers at the Durham, North Carolina-based startup Semprius have found a way to tackle both these issues by simply stacking solar cells. The technique enables Semprius to produce solar panels with efficiencies as high as 50% (compared to the industry standard of 25%).

    Good for hydrogen over area? less area over space so extra is stored hydrogen and or methane, or hydrogen peroxide method to hydrogen production, as well as electrical devices, not affected by shade?

    They have product available for demo projects, contact them.
    Be great if they could come up with portable demos for schools and groups – highlighting the synergistic enviornmental effects – less energy and pollution creating smaller chips, easier recycling of plastics and glass in concentrators. I bet their carbon foot print is less than half that of conventional PV arrays.
    While concentrating PV modules have been tried before, these folks are upping concentration much more, 1000:1 concentrator to and to a chip twice as efficent as before, so they might have a winner.

    The article does not day if they have product on the market now or when they will? Why not now since they are all ready better than solar cells on the market.
