Photovoltaics and Nanostructures Laboratory
|
|
| |
|
|
|
|
The Photovoltaic and Nanostructures Laboratory provides an interdisciplinary approach to R&D problems in photovoltaic materials and devices. Projects investigate a wide range of fundamental and applied materials problems to improve cell efficiency, increase power/weight ratios, and decrease the cost of high efficiency solar cells. Under development are sophisticated new III-V quantum-scale semiconductor materials and solar designs with projected efficiencies in excess of 40%, and new photovoltaic energy concepts that will enhance planetary and deep space exploration.
