NANOSTRUCTURED ARRAYS FOR RADIATION CAPTURE STRUCTURES

摘要

Silicon nanohole arrays are disclosed as light absorbing structures for various devices such as solar photovoltaics. To obtain the same ultimate efficiency as a standard 300 micrometer crystalline silicon wafer, nanohole arrays require less silicon by mass. Moreover, calculations suggest that nanohole arrays may have efficiencies superior to nanorod arrays for practical thicknesses. With well-established fabrication techniques, nanohole arrays have great potential for efficient solar photovoltaics.
