Strategic Options for a Led-Like Approach in III-V Concentrator Photovoltaics

Well-designed strategies are required in order to push III-V concentration to low cost scenarios that beat the prices of the already existing silicon-based concentration systems operating at 250-400 suns. Several laboratories and pilot production lines are starting to use in III-V solar cells similar approaches than those used for LEDs (Light Emitting Diodes). We firstly proposed the so-called "LED-like approach" in 1997. From then, we have analysed theoretically its main aspects thus guiding our manufacture developments with high concentrator III-V cells. This paper goes a step forward in the description of the "LED-like approach" advantages and in the influence of such approach on final cost
