چکیده

Only ten micrometer thick crystalline silicon solar cells deliver a short-circuit current of 34.5 mA cm(-2) and power conversion efficiency of 15.7%. The record performance for a crystalline silicon solar cell of such thinness is enabled by an advanced light-trapping design incorporating a 2D inverted pyramid photonic crystal and a rear dielectric/reflector stack.

Efficient light-trapping nanostructures in thin silicon solar cells

We examine light-trapping in thin crystalline silicon periodic nanostructures for solar cell applications. Using group theory, we show that light-trapping can be improved over a broad band when structural mirror symmetry is broken. This finding allows us to obtain surface nanostructures with an absorptance exceeding the Lambertian limit over a broad band at normal incidence. Further, we demonst...

Microsystems-Enabled Photovoltaics: A Path to the Widespread Harnessing of Solar Energy

Abstract If solar energy is ever going to become a mainstream power source, the technologies for harnessing sunlight have to become cheaper than all other forms of energy, be easy and quick to install, and work more safely, reliably and durably than present-day grid power. Our research team is striving to make this happen by utilizing microdesign and microfabrication techniques used in the semi...

Nano-Photonic Structures for Light Trapping in Ultra-Thin Crystalline Silicon Solar Cells

Thick wafer-silicon is the dominant solar cell technology. It is of great interest to develop ultra-thin solar cells that can reduce materials usage, but still achieve acceptable performance and high solar absorption. Accordingly, we developed a highly absorbing ultra-thin crystalline Si based solar cell architecture using periodically patterned front and rear dielectric nanocone arrays which p...
