High-Efficiency, Flexible, High-Stability Solar Cells

Nanotechnology-based hybrid nanocrystal inorganic thinfilm photovoltaics combine the best features of solar cells constructed from bulk thin-film silicon and from polymer solar cells. The colloidal nanocrystal (NC) cell technology offered here allows the production of air-stable solar cells processed using solution phase methods. The technology simplifies fabrication under ambient conditions, thus expanding the range of flexible or conformal substrates that can be used.

By using mixed blends of semiconducting nanocrystals in forms such as nanowires, nanorods, and quantum dots in a cell, and by varying their parameters, the cell’s response to irradiation can be precisely tuned to the wavelengths that favor the intended application, enhancing a cell’s potential output. The technology suite offers technical know-how and possibly production of nanotech materials.
