Paper Abstract

For terrestrial applications, the cost of photovoltaic power must be reduced by orders of magnitude. The usual approaches to low cost cell fabrication have many unsolved problems. Specially-constructed AlGaAs/GaAs heterojunction solar cells operated with large factors of solar concentration have reduced the projected cell cost per watt to an economically feasible level. The electronics for a two-axis run following tracking system are also sufficiently inexpensive. Therefore the ecomonic feasibility of a concentrator GaAs solar cell based terrestrial photovoltaic power system depends on the development of low cost optics capable of high values of solar concentration.
