Typically the films–used by organic bulk heterojunction solar cells, or BHJs, to convert solar energy into electricity–are created in a solution by mixing together conjugated polymers and fullerene
In the EpiWafer technology, a thick crystalline silicon layer is epitaxially deposited and subsequently detached after growth to produce a freestanding wafer of standard thickness.
Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current.
Solar conversion efficiencies of over 20% have recently been achieved in CIGS solar cells.
Now three Stanford engineers have developed a technology that improves on solar panel performance by exploiting this basic phenomenon.
DOE’s SunShot program is announcing $32 million in awards for 14 projects to advance all technical systems of CSP plants, including solar collectors, receivers and heat transfer fluids, thermal energy storage, power cycles, and operations and maintenance.
