✦ Synopsis
A new theoretical model is presented for the performance of solar cells when light in the shape of a cone impinges on them. This is the case for concentration applications. The model is applied to 1000 sun concentrator p/n heteroface GaAs solar cells for the general purpose of a cone angle of between 08 and 908. A multidimensional optimization of the whole GaAs solar cell structure (antire¯ecting coatings ohmic contacts semiconductor structure) is carried out. It is the ®rst time that the whole structure has been simultaneously optimized under a maximum eciency criterion. This is thanks to the dual consideration of the opto-electrical characteristics of the window layer. An assessment of GaAs solar cells working inside optical concentrators is also derived.
