Abstract

Disclosed herein is a system for generating electrical power from solar radiation utilizing thin-film III-V compound multi-junction semiconductor solar cells mounted on a support in a non-planar configuration, be it an aircraft, watercraft or land vehicle .

Description

technical field [0001] The present invention relates generally to solar power systems for converting sunlight to electrical energy, and more particularly to solar cells using III-V compound semiconductors. Background technique [0002] Commercially available silicon solar cell efficiencies for land-based solar applications range from 8% to 15%. Compound semiconductor solar cells based on III-V compounds have an efficiency of 28% under normal operating conditions and 32.6% under confluence. Furthermore, it is well known that concentrating solar energy onto photovoltaic cells increases the efficiency of the unit. [0003] Considering the low cost and wide availability of silicon solar cells, land-based solar power systems currently use silicon solar cells. Although compound semiconductor solar cells have been used extensively in satellite applications, where power-to-weight efficiency is more important than cost-per-watt considerations in selecting such devices, such solar c...
