SOLAR CELL EFFICIENCIES THROUGH PERIODICITY

摘要

A solar cell includes a photovoltaic material region. The photovoltaic material region is covered by a uniform anti-reflection coating. A photonic crystal structure is positioned on the photovoltaic material region. The photonic crystal structure provides a medium to produce a plurality of spatial orientations of an incident light signal received by the solar cell so as to allow trapping of a selective frequency of incident light in the solar cell.
